How does National Geographic film the wildlife without obstructing it? | Nature photographer here. You get shots like that by crouching motionless in a cold, wet camouflaged blind for days or weeks, waiting for the one perfect shot. It's not real glamorous work. Long telephoto lenses are frequently used, but they're not always an option. I use a Nikon 600mm lens for much of my nature work. ... |
What is actually moving through all these cables/lines ... | Instead of bursts, they're all continuous signals. While the signals for old fashioned telephone via PSTN or ISDN and the like are only transmitting when the machine is used, they're still continuous signals. An analog signal differs in amplitude and frequency as one would expect. A digital signal takes that and makes ... |
Why is weather so unpredictable? | Imagine you drop a plate to the floor and it break in so many parts. It is almost impossible to predict how all the parts will spread out on the floor or how will they break before they do so. The weather is similar to the parts of plates on the floor, although we know how it works, there are so many variables and poss... |
Why do dogs and cats eat their vomit? | If they're doing it at home it's an instinctive behavior to keep the "den" clean. In the wild, after having puppies, a mother wolf has to remain largely stationary to take care of them. Puppies poop, so the mother eats their feces to keep them from eating/rubbing on it and getting sick. Other members of the pack will d... |
what's the deal with the vacancy on the US Supreme Court? | The president selects a nominee, and the United States senate confirms that nominee or not. Presently, the above two actors are opposed in political outlook, and senate is refusing to confirm or reject the nominee the president has selected. there does not appear to be any legal requirement for them to do so in any giv... |
How does every game artist in a company draw in the same style? | Game companies have a special artist role in place in order to ensure that. They are called "Concept Artists". A concept artist's role is to draw the material that will be used as a reference point by the other modelers, texture artists, animators, etc Since the reference drawings all have the same style, the actual ga... |
Why does going cold turkey from alcohol kill you compared to other substances? | The human brain produces a substance called gamma-Aminobutyric acid, GABA, which is a neurotransmitter that regulates healthy brain activity by controlling the speed at which neurons fire. You've heard alcohol described as a depressant; this is because its effect on the brain mimics that of GABA, slowing neural activit... |
How can snowboarders fall 5 stories and not break their legs ? | A) Snow is softer than dirt B) Just like motorcycle riders, they try to land on sloped ground so you're *not* dealing with the entire impact as a blow to the legs |
How does HIPPA work? | It's way too involved to answer in ELI5 format. We have a full-time, well educated person just to oversee compliance. Basically the only reasons protected information can be shared if for continuation of care, to obtain payment, and for QA. Perhaps a more relevant example for your question, as the person who creates al... |
why do kids add y onto everything? Daddy, mommy vs dad or mom | You do realize that kids use the words they are taught? It's not like they came up with the word mommy or daddy. The people around them use those words so the children naturally pick them up and use them. "Go show mommy your picture |
Why do journalists put random things in brackets in their articles? | So if you're quoting someone, but they are using pronouns that wouldn't be clear if you just quoted them directly, you use brackets to clarify. So in this case, if the person being interviewed said "It is our primary source of school news." but the article talked about the campus newspaper and the campus radio station,... |
How do whales and dolphins sleep without drowning? | I read about this recently. I believe dolphins can sleep with half their brain at one time so essentially they both get the benefit of sleep while they're partially awake. |
How do venomous snakes avoid self-envenomation? | They actually are susceptible! There's two things to consider. 1 - They swallow their own venom and 2. They accidentally bite themselves and inject their own venom. If they were to swallow their own venom, no harm is done as the venom is made of protein which gets destroyed by the juices in the digestive tract. The oth... |
How did we find out how different animals see the world? (And how accurate is this wisdom?) | They dissect the eyes and study the structure and types of receptors that they have. If the receptors react to ultraviolet light then the animal can see in that range of the light spectrum.Having receptors in their eyes is pretty strong evidence, don't you think? Those receptors can be extracted and the electric signal... |
Why don't baseball pitchers wear a protective helmet if a line drive could cause permanent brain damage among other things? | Simply put, pitchers don't want to wear them. It's as simple as that. As far as I know, it's perfectly legal for players to wear helmets in the field and it has been done before . Here are the reasons I've read about that account for the resistance to pitchers' helmets: 1) While the effects of getting hit can be bad, i... |
How can it be cheaper to buy a flight ticket from a travel agent than the airline itself? | You're only trying to buy one ticket from the airline. The agents buy 100s and get a discount.We usually get a discounted or agent rate. Sometimes we get packages as well!Buying from airline is the retail price. Buying from agent is contracted wholesale price. |
Why do my muscles seem bigger right after a workout? | Because they do swell. They fill up with blood which is diverted to feed their consumption of resources.Apropos of the topic, albeit not answering the question directly. [If you want to see muscular definition, you want low body fat.] You need to workout too, of course, otherwise you'll look like a marathon runner or t... |
Why do "No shirt, No shoes, No service" signs not include pants? | If you aren't wearing pants you are getting arrested. It's necessary, of course, so much so that including would be overkill. |
Why does pressing a button on a remote control seem to work better when pressed down harder? | When you press a button on a typical remote , it emits a pattern of infrared signals repeatedly until you let go. Once the TV or whatever picks it up, the action happens. When you press down harder, it's not the pressure that's doing anything, it's that you are also pressing it *longer*, and that emits more cycles of t... |
What is the deal with the sound barrier? Why does it make a "boom" when it's broken? | Any plane makes a wave, much like the visible ones when a ship moves across water. The faster you go, the waves in front of you are piling up because you're getting close to their speed. At mach 1, the waves form and pile up directly in front of the plane. Breaking the sound barrier makes the plane literally Pierce thi... |
Why do countries with stronger eeconomies have lower numerical values on their currency? (eg. 1$=1000 wons of south korea) | I believe the Won is much like the Japanese Yen. Instead of having fractions of one monetary unit , they simply removed the decimal point from their currency. So, one Yen is one penny, and 100 Yen is 1 dollar. Then the exchange rate comes in to effect. So, say for example, the Yen/Won and the US Dollar were perfectly e... |
How come the water source of a waterfall doesn't run out? | It is rain. Take Niagara Falls. It drains the upper portion of the [St. Lawrence Watershed]. Most every drop of rain that falls in Michigan or southern Ontario is going to find its way to Niagara Falls. So if it rains one inch, that one inch across maybe a quarter of a million square miles, all of that funneling throug... |
Why are the sides on a ship called Aft, Port, Bow, and Starboard, instead of Front, Left, Right, and Back? | because then it doesn't matter where you are standing. They reference portions of the boat and not the surroundings or your perspectives. This makes communication clearer. |
Are light bulbs easier to break because of all the pressure inside it compared to other things? | Pressure inside puts the surface under tension, which makes it easier to break in certain ways. The tension helps it from breaking in other ways. Light bulbs actually have a slightly lower pressure inside so that when the inert gas around the filament heats up, the pressure doesn't crack the glass. > could you realisti... |
Why do people play "games" in their heads? | Neuroscience has taught us that certain repetitious behaviors dictate the direction of brain-flow. Yeah. We'll call it brain-flow. Think of it like taking the same path to school or work every day, and then taking the same path between all of the various places you travel. Your brain gets good at recognizing consistent... |
How does a Zip Bomb work? | Compressing data makes use of patterns that are more compactly stated by giving instructions. For example, if the file was "00000000000000000000000000000" then that could be compressed as "repeat \'0\' 32 times." The bottom layer is a file that says something to the effect of "repeat \'00000000\' 4.3 billion times." Th... |
How does talcum powder cause ovarian cancer? | It's still not know for sure if it actually does, but there's a few factors to consider. 1. Some talcum powders contained asbestos, which is now a know carcinogen 2. Talc is known to be an inflammatory agent, and a pretty potent one. Chronic inflammation has a link to some cancers because it disrupts the immune system,... |
Why hotdogs are not a normal item at fastfood places? | In some places they are. It's merely a cultural preference; there is no scientific reason for it. Why apple pie and not peach? |
Out of all birds, why did humans made the chicken staple diet ? Why not goose, sparrow, eagle, crow, duck or anything else? | We want birds that are easy to keep, breed relatively quickly, give plenty of palatable meat, etc. But chicken is not the only bird kept for its meat; goose, duck, pheasant, quail, and dove are all raised for their flesh. Eagles would be difficult to handle and not worthwhile to feed; crows don't have much meat and are... |
What does conditioner (for your hair) actually do? And how does it do it? | Shampoo's main goal is cleaning hair. During the cleaning process a lot of the natural oils are stripped from hair. Conditioners add back things like oils to undo some of the less-desirable effects of Shampoo. Fun Fact: modern chemistry has managed to merge shampoo and conditioner pretty well into one product. Some sti... |
If millions of Native Americans died from European diseases that they had never been exposed to, why didn't American diseases spread equally terribly to Europe? | Livestock. The majority of our worst diseases come from our interactions with livestock, especially ducks and chickens. Other than the clean and healthy llama, livestock was never kept in North America, and the cesspits of disease that result from primitive ranching methods never developed eitherThere is a theory that ... |
Why can't the HPV be cured? | There are exactly zero viruses that we know how to cure. Influenza? Nope. Chicken Pocks? Nope. HPV? Nope. When people give you medicine for viral infections its either an antibiotic or a medicine specially designed for treating the symptoms. That's it. The medicine makes you more comfortable while your body defeats the... |
If fruits are meant to be eaten by animals, why are some fruits poisonous? | Fruit isn't *meant to be eaten by animals*. Plants reproduce in *many different ways*, only one of which is by producing seeds inside of tasty fruits for animals to eat, walk off, and then shit out the seeds elsewhere. *Some* fruit is tasty and meant to be eaten, whereas some fruit is poisonous and used to ward off ani... |
Those random muscle twitches you get in your arms and legs | Fasciculations. Fasciculations are caused by something irritating the nerve fibers and can just kinda happen. There isn't one specific cause for this, but the majority are benign and pretty much no one has any interest in studying the majority of causes. Some Fasciculations can be the result of a health issue , but for... |
What is the reason for banning assault rifles? What makes them different than a semi-automatic hunting rifle? | The "assault weapon ban" doesn't ban assault rifles. It bans scary looking guns. Yes, you are correct that the guns banned in the "assault weapon ban" are not particularly different as far as killing ability from a semi-automatic hunting rifle. Fully automatic assault weapons are still legal. Banning those might inhibi... |
The scientific basis to the illusion of free will | Basically our brain acting like a computer, it is designed to do something, thus it is predictable. Our only issue is we don't posses the knowledge to predict it, yet. |
Why/how do some people hold the belief that only white people can be racist? | There are two kinds of racism, personal and systemic. Personal racism is when an individual judges a person based on the color of their skin. Anyone can be racist, of course. However, the systemic racism in the US is geared in favor of white people and against people of color. For example, the old practice of red linin... |
How can a phone make emergency calls without a sim card? | Because any network will allow any phone to make an emergency call without worrying about whether it has a contract with that network or any other. Emergency calls are handled specially - the phone just tells the network "connect me to the emergency services" rather than dialling the number normally. Hence you can use ... |
Whats Happening with the Bitcoin Right Now? | It means everyone who had bitcoins on the Mt. Gox exchange lost their bitcoins. 744k bitcoins are gone. Not sure what this means for Bitcoin in the long term. There are other exchanges, of course, but what happens to the confidence of people who own bitcoins at this point is anyone's guess.Edit: Here's a graph _URL_0_E... |
Do women actually live longer than men? | Statistically yes, but only because more men tend to do more hazardous and strenuous jobs than women do.Yes, slightly. Age expectancy at age 65 in 2012 in the 'States was 17.9 years for men and 20.5 years in women. Source : _URL_0_ |
Why is reddit not more commercially successful considering its loyalty and views per hour/day? | The loyalty and views makes it very expensive to run. The website essentially runs for free. Besides the few advertisements, that you never actually notice. Websites like Youtube, and Facebook rely heavily on Advertisements, which in turn makes it profitable. Websites like Wikipedia, which has no ads at all, run simply... |
Quick Grammar Question in Honor of the New Subreddit | that's a good question. I think part of this subreddit's appeal is that it is a safe place to ask questions without fear of getting harped on for not understanding or already knowing the answer. So, as long as it's pointed out politely and instructively? |
Who do people who are wrongly accused and imprisoned of a crime behave so complacently and quiet throughout the whole process and subsequent incarceration? | Because whether or not you are actually guilty doesn't really matter -- your lawyer is going to tell you to keep your shit together and not act insane either way. If screaming got you out of jail, truly guilty people would do it too ", 'Because they're being smart. Yelling "I'm innocent for these reasons!" to the polic... |
What is the history of academic regalia? Has it always been worn during graduation ceremonies? Is there any symbols in the hats and hoods? | In the US it has always been worn in ceremonies. It was inherited from the British University model where that regalia was the school uniform that they wore at all times. This itself was evolved from the fact that during the middle ages and early renaissance all Universities were a part of the Church and education a se... |
Why, historically, do socialist countries often experience economic collapse? | An open market allows consumer needs, wants, and demands to match up with producer supply spontaneously and organically. A top down planning approach fails because leaders and decision makers in overly socialized economies are not capable of actually anticipating and providing for consumer needs and wants. To bring tha... |
What is the difference between irony and coincidence? | If it's unlikely for you to run into your cousin overseas, it would be called a coincidence if it actually happened. If you went overseas to get away from your cousin, it would be called "ironic" if you ran into her in Venice. So both are just surprisingly unlikely situations, where the coincidence is called "irony" if... |
How come the water feels a lot colder if you drink it right after having a mentos? | We have receptors that are triggered by certain chemicals . Hot and cold is a sensation our tongues use to inform the brain of chemical potency and makeup. For example if you eat a whole chili pepper your mouth is on fire, not that the pepper is bad for you but we as mammals have not evolved to be the primary distribut... |
How do hospitals discard human remains/surgical cut-offs? | Usually picked up by a medical waste disposal company that either incinerates them or hydrolyzes them with hot lye. |
Why is alcohol such an amazing carrier for extracting flavor and smells? | Just to add to what has already been said, alcohol is great because it is very volatile , besides being only slightly polar and safe for consumption for non crazy amounts. for perfumes, it's great because it dissolves the oils that give it its scent and when you spray it on yourself, you spray both. In a few seconds, t... |
On a telephone, why does ABC start on the number 2 and not 1? | Because 1 are universally used to indicate international dialing which means that no local phone number could possibly start with A B or C if those letters were on the 1 key. EDIT: 1 is for long distance dialing of any kind, not just internationalIt used to be telephone exchanges used to be a name , and maybe a digit a... |
How did Vietnamese monk Thích Quảng Đức achieve such an extreme pain tolerance? | If I remember correctly, during immolation the extreme heat can burn the nervous system, basically killing the cells that would carry the signal of pain to your receptors. The flames would be so hot that they destroy the nerves responsible for fast and slow pain, meaning the body doesn't react like it normally does by ... |
How do tornadoes form, and sustain their vortex? | Ever watch water going down the bath tub drain? Even though the water was relatively motionless before you opened the drain, the low pressure area you introduced by opening the drain causes a rotating vortex to form in the water. Tornadoes work in much the same way. They're associated with low pressure areas, after all... |
before plumbing, how did people in large cities get water? | There are many smaller rivers and streams flowing into the Thames in London, the Fleet is probably the best known. For the most part they now flow through underground channels. [List here.] Combine that with private and public wells and manual pumps. It's never particularly been short of water of various qualities. The... |
Does working out stunt one's growth? (Everything reliable I find on google is way beyond me) | "It stunts your growth" is a sorta catch-all bullshit statement people say when they want to dissuade kids from certain things. I am fairly certain that there is no food, drink, or activity that can reliably make people shorter or taller. I suppose the region you live in could affect your shape, like the barrel-chested... |
Why is it that whenever I read about or see bugs, I get the feeling they are crawling on me? | Notice when someone brings up lunch or food in general, you might feel more hungry after hearing that. Like the power of suggestion', "It's called suggestibility. It's a form of hypnosis |
Why does it seem some cultures have a single name that is so ubiquitous - Muhammed, Jose Gonzales/Sanchez, etc | They are relevant names in that culture, mostly religious. Large Muslim influence in the middle east and Mohammed becomes a popular name Christians also use biblical names like John, Jesus, Matthew, David, Sarah, Mary, Michael. Last names tend to be associated with professions, locations or family lineage. Smiths are m... |
how do some areas have more than one power supplier since I would assume they would be using the same power lines and infrastructure? | There are a number of ways thus can be done, but in general the model breaks the system up into different parts. The first part produces electricity. There are numerous power suppliers, e.g. dam operators, coal plant operators, nuclear plant operators, etc. These power generators sell their output to various distributo... |
Why can cows live on grass, while humans require such a complex balance of nutrition? | Cows have an insane digestive system that's capable of deriving a *lot* more nutrients out of grass. You may have heard that cows have four stomachs, for example. We don't have that . Humans, OTOH, are omnivores who spend way less time eating and so eat things that are more calorically dense and use vegetation as a nut... |
How did/do scientists find out how the brain works? | The easiest way of finding out what something does is looking at it when it's broken. A lot of discoveries on the brain were made by looking at those with brain injuries; injuries that resulted in the loss of speech, vision, consciousness or even death. Also, post-mortem investigations revealed a lot on how certain blo... |
Why is target fixation much more common on motorcycles than when driving a car? | Have you ever heard the expression "where the eyes are so goes the hands"? If you are driving a car and stare at something in the rear view mirror you will more often than not end up drifting off to the right. Same as if you are watching something to the left. Your brain is directing your body in the direction of your ... |
With Katrina's 10-year anniversary looming, why no focus outside of New Orleans? | Because most of the death toll for Katrina was in Louisiana, with the bulk of that in New Orleans. While the storm had devastating impacts and loss of life along the gulf coast as well, what people remember is the television coverage of New Orleans.NPR has done several stories outside of New Orleans. Mainly pieces on s... |
standing water is usually nasty and full of bacteria and growth, why do wells have such clean water? | Some wells are very contaminated. But most wells contain water that has been highly filtered by passing through layers of minerals since the last time it was exposed to bacteria or algae. The very best wells have water that fell as rain *thousands of years ago* and have been trickling through rock and sand since then.I... |
How do Cell phone towers work/get their service? | I dunno how ELI5 you're looking for. But basically a cellphone is actually a radio transceiver and the cell towers have transceivers as well. Each tower is ultimately wired up to some form of a landline in order to provide telephone and Internet service. As you move around, your cellphone connects to the tower that is ... |
How do fiber optic cables work? Where do you plug in a fiber optic cable to get internet? | You get Internet by connecting your router, via some cable or radio link, to someone else's router who is already on the Internet. An ISP is a company that's in the business of renting out connections to their router, and in turn they have connected their giant router to some mega-size ISP . Their giant connection to t... |
What happens to a country's old flags when the design changes? | Well, I'm old enough to remember when Alaska and Hawaii were admitted as states within a few months of each other in 1959, and the number of stars on the US flag officially went from 48 to 49 and then 50. I was 11 years old, so I may not have known a lot, but I *think* what happened is this: important places like the U... |
why is gold is the most valuable “currency” that can get accepted almost everywhere | You'd have a hard time actually spending gold in most of the developed world. Retailers only take government currency. In past centuries though, gold was valuable for its rarity, workability, and corrosion resistance. Silver oxidizes to a dark black tarnish over time. Copper turns green. Iron turns to dust. Gold is gol... |
Is it true that we dream whether or not we remember it? If so, how can we prove that we do? | When you sleep, your brain alternate between different levels of sleep, from regular sleep to Rapid Eye Movement sleep. It has been shown that almost every time you enter REM sleep, you dream. During REM sleep, your brain is very active , presumably that's what's generating the dreams. Scientists have been able to wire... |
Why can't you 'reactivate' features on lower end processors? | Usually these cores are physically destroyed.They are disabled because they were found to be defective or not perform in the same temperature and voltage range as other cores on the same unit. Re activation, if possible, would likely result in errors due to overheating, or even damage to the rest of the chipset. The lo... |
Why do they call it a season of television in the US but call it a series in Britain? | Network TV in the USA has a pretty regimented schedule, running from fall to spring, with around 23 episodes per program, year after year. With this sort of regularity, it makes sense to call it a season. In the UK, programming is more irregular. *Sherlock*, for example, only did three episodes a year, once every two y... |
In English, is there a name for words used as a base for other words never used alone. Ingress, regress, progress, digress are all words but "gress" isn't. | The other answers so far are wrong. It is not a suffix. It is a bound morpheme. A bound morpheme refers to any piece of a word that can't appear in isolation. That is, a suffix is a *type* of bound morpheme, but there are other types of bound morphemes other than affixes . In fact, the examples you listed contain bound... |
Licenced, Insured, Bonded - What does this mean when displayed/advertised by a Contractor (construction trades) | Licensed means they have a license to that particular work in that jurisdiction. Some occupations almost always require licenses while others sometimes do and sometimes don't . Insured means the contractor has insurance. Typically it refers to worker's compensation, meaning that if a worker gets injured on the job the ... |
When the large Baby Boomer generation begins to die and their homes flood the market, will real estate prices drop dramatically? | Real estate in certain areas that have very high boomer populations might suffer some but it isn't like they are all going to drop dead on the same day. [Boomers are about 20% of the population] but they live all across the US and there is wide range of "normal" life expectency as well as untimely deaths that will "smo... |
Why are the stars white but the sun is yellow/orange? | Stars are many different colors, Rigel is blue. However, the eye has a special gain processing system that is more sensitive in what could be called "black and white mode". At very low light levels, the eye gives up color discrimination in favor of higher sensitivity. In that mode, there isn't enough light to support t... |
Is the belief that mother birds abandon baby birds that have human scent a myth? | Birds have relatively small and simple olfactory nerves, which limit their sense of smell. It is a myth and only that. Bird will not abandon their young if the young bird is touched by a human for some time. However, if the nest is disturbed it's possible they will abandon it, but if they have feeding young it is highl... |
Why is American butter white? | American Butter, the standard is grain fed; not grass fed like european standard.

Why I feel sick when I am very hungry | Not an answer to your question at all, but this has to be the most counterproductive thing the human body does. When I'm hungry enough to feel sick to my stomach moving to get food is the last thing I want to do, which makes things worse. |
What are the pros and cons of organic farming versus conventional farming? Which one is better? | The main advantage of organic farming is that you can put the organic label on the stuff you sell and charge more for it. The disadvantages include smaller yields, greater chance of disease, greater use of pesticides, and greater environmental impact.Which is better is up for debate. Some of it comes from people's trus... |
If I shoot a basketball, and miss, 1000 times in a row, would I get better because of repetition or would i just develop bad muscle memory? | Practice doesn't make perfect, practise makes permanent. If you have enough understanding and feedback to refine the movement, you'll improve. Missing one thousand times would suggest you weren't improving the movement, either because you're moving randomly our because you're repeating a movement that is ineffective/wr... |
How are we able to look "back in time" to the origins of the universe when the light should be well past us? | First, you are experiencing a common mistake with the balloon analogy. The universe isn't like the area within the balloon, it is like the *surface* of the balloon. The intent is just to show how an expanding area results in all points moving apart with the more distant ones moving faster, when people are not generally... |
How can ISP's provide new Ip address each time a modem is reset or every few days? | An ISP is assigned a block of IP addresses that they own & can give to customers. When a device comes on, it screams **WHO AM I?** out to the network & a [DHCP server] at the ISP responds with an IP address. Periodically, the device will contact the DHCP server and say "I'm still using this address, please don't give i... |
How does a road work when it crosses the border of a country where cars drive on the right and a country where cars drive on the left? | They split the lanes. At some point one goes over another and then they recombine in the new configuration. This complex maneuver can be achieved by a technology called a "bridge". |
Why are people from the Horn of Africa so good at running? | They live at high altitude, so their lungs are more efficient. Much of the countries are not paved and many don't have cars so running is a form of transportation, and many do it as part of work.From what i believe is that they practice a lot and have good genetics that help them be a stronger runner |
Why do some penises have a slight curvature and others don't? what causes this curvature? | Straight from wikipedia- "A certain degree of curvature of the penis is considered normal, as many men are born with this benign condition, commonly referred to as congenital curvature" But there is a medical condition that can cause the curvature- "Peyronie's disease , also known as induratio penis plastica[1] or chro... |
How did people meet up before cellphones, internet, telephones, faxes, telegraph etc.? How did anyone find each other and conduct business? | letters. it was a lot slower. for example, the battle of New Orleans occurred after the treaty that ended the war of 1812 was signed. the treaty was signed in Europe and news took time to reach America. This led to newspapers first posting that Andrew Jackson won the battle of New Orleans, then weeks later the news of ... |
ISIS and what their goals are | I've removed your post as it's been covered multiple times. Further, the question is better suited to /r/outoftheloop As /u/JMFargo pointed out, [This] post over there should answer your question fully.This was asked over [here] and [the top comment] answers it amazingly well. |
why some Kindle books are not available in my country? | This is a hold-over from the physical book era. When physical books had to be printed, publishers had local partners in many different places in the world that did local marketing, printing, and distributing to local bookshops. So if you were in New York, you didn't have to talk to a book shop in Switzerland. There wou... |
how formalin conserves, preserves and fixes organic tissues | The technical name is formaldehyde. Formaldehyde is toxic because it forms "cross links" aka "adducts" with both proteins and DNA. That is, forming chemical bridges between nearby protein chains , DNA helices, or both. This deactivates these important molecules. So formaldehyde acts to sterilize items. This includes pr... |
- Why is there a female-centric subreddit as default but no male counterpart? | Because default reddits are not chosen like that. They are chosen by the level of traffic, the rate of new subscribers, the average number of users online, and the amount of content being posted. So the answer to the question would be that the "female"-centric reddits meet those criteria while the male ones do not. |
Why dose it hurt more if we get hit when were cold? | It's actually a defence mechanism. When cold your blood tends to surge further towards your important internal organs to keep them warm and functioning. This means external skin damage cannot react/repair as quickly so your nerves send a more serious pain signal. |
Why is there no sales tax on groceries but there is at restaurants in America? | This is done on a state-by-state basis. Some states will tax groceries while others will not. All states have a tax on prepared foodGroceries are a necessity, eating out is notMany states consider groceries to be a necessity, and therefore tax exempt, while restaurants are a service which is taxableThere are 2 taxes in... |
if I were to be eaten whole by a whale or some other large animal, how would I die first? Would it be painful? | Since you are being "Eaten" whole there won't be any mastication but there will be suffocation. Also fish breath whale reflux that has got to burnI believe there was a case of a man a few hundred years ago that got swallowed by a whale. He eventually came out, but the stomach acids had turned him ghost white. Hair, ski... |
What happens when two viruses or diseases inhabit the same body? what if the same body part? | Generally viruses have very specific molecular targets inside the human body.If the viruses are pathogenic that means you will likely get both diseases.Viruses are much smaller than cells, that means many of them can infect the same cell.
