Why can't you smile in your passport photo? | Apparently it messes up facial recognition software - from the [Canadian passport website] > Why can't I smile in my passport photo? > The International Civil Aviation Organization recommends that passport photos be taken with a neutral expression for use with facial recognition systems - advanced technology that helps... |
Why do hotels charge a higher price for more than two guests in a hotel room? | You're paying based on occupancy and they figure that based on the beds. A king bed is for one person or a couple who shares, two twins would be for two people, a multi-room suite for a family, and so on. If they found out you had an extra person, you'd get charged a fee. If no one found out, then nothing happens. I us... |
Why do mental illnesses such as schizophrenia and depression occur in humans? Are they considered mutations or are they genetically wired in our brains that will emerge when a significant event occurs? | It sounds like, from your wording, that you think everything in the human body occurs to serve some purpose. It's a common misconception that evolution works in a way that makes each change for the better, to serve some purpose. This is not so. Many things are just not-harmful, or not-overly-harmful, so they're not sel... |
what exactly is "due process"? | Interesting you ask this. I'm working on a paper with some referencing to the amendments and have had a hard time grasping it myself. Someone knowledgeable on the subject would be very helpful! |
We construct our thoughts using language. For someone who doesn't understand any language, what is going through this person's mind when he perceives or thinks about something? | You don't construct thoughts using language. You use language to express thoughts. It's the exact opposite of the way you're describing it. |
Why Terror groups take responsibility for things | The point of terrorism is to bring attention to a political or religious cause through the use of violence and fear. If no one knew why it happened it would defeat the purpose, and knowing that there is a group plotting your death just makes it scarier. Terrorist groups are not official organizations with a storefront ... |
How did sexual production begin? There needed to be a male and female sexual organs! | Evolution typically produces complex adaptations by doing simpler things first. There are many precursors to the sexual reproduction in humans, even among modern living things. Early sexual reproduction involved fusing arbitrary pairs of sex cells outside their creators' bodies. This encouraged the existence of cells w... |
Why do we smile? Most species show their teeth as a sign of aggression but we show ours in happiness. Why? | I don't know much about the biological side of things, but in terms of history I do know a toothy smile was considered crude in the low countries around the 17th century. You generally only smiled with your lips, unless you were a drunken uncouth peasant! I think in Victorian England this was the case, too. So in terms... |
Why do so many older songs end with the music simply fading away? | I don't think it's a coincidence that the fade was at its peak during the golden days of FM radio. DJs were motor-mouthed gods then who loved to talk over both the intros and outros of songs. If nothing else, the fade gave them a place to jabber without destroying a vital piece of the song.I'm a musician and have a few... |
What happens to my daddy when he joins the
military? | He goes to work, but his work is far away, so he can't come home at night. He'll be gone a long time, then he'll come home for a while, then he'll probably go again. This might be a part of your life for a long time. He's doing a tough, dangerous job and it doesn't pay very well. He deserves respect for volunteering to... |
Why do females have higher voices than males? | Might have to do with how screams of pain sound differently between men and women. Causing or ignoring a female's cries of pain makes a sound more like children whereas a man's pain sounds unique. Evolutionarily to protect reproduction, perhaps we are wired to be more averse to pain associated with pregnant women, and ... |
Why are Oscar movies almost always dramas? | A good movie, in a general view, can communicate very well and create a good identification with its audience. Dramas are most likely to achieve that because they discuss a human problem.For instance, once I read a movie critic say that every good sci-fi movie has a drama plot, so they wouldn't gap too much from our re... |
What would happen if the earth lost its magnetic field right now | There's some answers floating around that aren't correct A complete destruction of the magnetic field would be kinda a pain, but not for many years. Basically, you'd start getting a bit more radiation, so increased risk of skin cancer. Other than that, a large solar ejection could conceivably deal more damage with less... |
How do casinos have the "house advantage" when the player is the one who decides when to stop and walk away? | Your proposed strategy will not work because in real life the players money is finite, and therefore you will still be at a disadvantage. Suppose you bet $1 initially, and you have a maximum of $1023 available. You can then only bet 10 times before you run out of money. That situation occurs if you lose 10 consecutive ... |
When something is zero sugar and zero calories, what actually is it made up of? | If you want specific information you can check the ingredient list, but the vast majority of it is carbonated water. The flavors come from natural or artificial flavoring that has zero calories/close enough for the label to say it's zero, and the sweetness comes from one of several different types of sugarfree, zero ca... |
When does a stick stop being a stick and become a branch, or a log? | It's a question about more than length, width, and weight. You also have to consider its *essence*: in short, it depends on its degree of stickyness.I always thought of it as a log is the biggest limb of a tree, followed by the branches which grow off of the logs, and the sticks are the smallest, which grow off of bran... |
Why does a candle only smoke only after it's been put out? | Smoke is products from incomplete combustion. Incomplete combustion occurs when there is not the right mixture of air, fuel, and heat. An efficient fire will have very little visible smoke. When you blow out the candle, you take away most of the heat. The combustion still lingers a bit because you didn't instantaneousl... |
What happened in Morgan Freemans AMA, why he started getting downvoted. | High expectations I guess. Even if it was Morgan Freeman, people weren't happy with his one line answers as they expected something much more from him. |
Why is it impossible to default on student loans even through a bankruptcy? | The law says you can't discharge student loan debt in bankruptcy. That's really all there is to it. It makes sense. Why would you loan young people with no credit, no downpayment & no assets $40-80k if you knew they could just declare bankruptcy at graduation and suffer no major consequences? Everybody would be doing i... |
How does algorithmic stock trading add value to our economy? | I'm going to assume you're actually curious and don't just want to hear people tell you why they think it's bullshit. Essentially, these algorithms detect an opportunity to trade for a small amount of profit. The profit from this trade is very tiny, and the window of opportunity is likewise very small, so humans can no... |
How does Vladimir Putin have a ninth-degree black belt in taekwando while having not practiced it? | On a side note, Putin hired a trainer from the Shaolin Temple in Dengfeng China to teach his daughters kung fu. I've met the man, he's the cousin of a currently high-ranked monk in the Shaolin leadership. Putin is serious about his martial arts, I wouldn't want to fight him. |
Why you tend to feel more hungover the older you get? | I'm fairly certain it has to do with your metabolism slowing down as you age. It's the same with food, when your younger your body can keep up with all the bad food you eat but as you get older your body gets slower and you can't digest things like you used to. Hangovers are essentially just your body dealing with the ... |
What part of the mammalian reproductive system is responsible for the perfect 50:50 chance of the fetus becoming either sex? | The male testicles make the sperm that determine a babies sex. Because sperm is produced by splitting the chromosomes into 2 halves, x & y, there's an even split of male producing sperm and female producing. This even split is what should result in a 50:50 split. As others have said, that's not exactly what happens but... |
Why does time pass so swiftly while we are sleep? | Whats always puzzled me is this: I'll be having a dream where I am doing something and there will be a noise in my dream but it won't be random, there will be a whole lead up and reason in my dream for this noise .yet in reality, there was a noise in my house that woke me up at the exact same moment, and that noise was... |
Why do people typically have exclusively one hair colour while other animals like cats can have patterns of varying colours? | It's an illusion. If you analyzed every hair on your head, you would have hundreds of different shades of different colour. When they are all together, it just kinda blends into an average colour. On parts of the body where hair is less dense, it is easier to spot this. Especially beards |
how come humans and other animals can balance on 2 feet but other objects can not balance on 2 "feet" | Balancing on two feet is actually pretty hard to do. We and other animals can do it because we have muscles that we can adjust if we start to tip off balance and readjust our posture. A chair or a table doesn't have this kind of flexibility/conscious ability to adjust itself and just falls over. |
Magic the Gathering. How does it work and why do people spend so much time and money on it? | It's a collectible card game where you are basically a wizard who gathers mana and uses that mana to cast spells to defeat your opponent. People spend money on it because they enjoy the game, or maybe because they like the artwork on the cards or they enjoy collecting and trading them. |
Why is it so much harder to carry someone when they are asleep? Why do they feel heavier? | Their muscles being relaxed means you have to use additional muscle power to keep them from bending in a direction that would make them even more difficult to carry. It's kind of like trying to carry a piece of wood vs. a tarp. Even if the wood and tarp weight the same, the tarp is much more difficult to carry because ... |
Why modern PC games fit on one CD where older ones required many more. | Modern games are using DVDs for storage, as noted, but they also can download content by relying on larger hard drives. Even console games can have downloadable elements; we're not just talking about DLC, but major content patches that can be added to the game install through a network connection. |
If speakers have magnets, and magnets can mess with hard drives, then how can they put speakers in computers? | The magnets in speakers aren't powerful enough to disrupt a hard drive from further than a few centimetres, if even then. If you want to mess up a hard drive, you need a pretty powerful magnet. Problems would possibly arise if the speakers were installed very close to the hard drive.This actually was a problem back a f... |
if a person becomes unconscious and is taken to the hospital in an ambulance, is he liable for the bill? Why or why not? | Unfortunately you'll be stuck with the bill. My sister had heart issues in high school and passed out during cross country training. Ambulance was called and mom was stuck with a 3500$ Bill even though the paramedics didn't do anything but arrive and check her vitals since she was awake again before they arrived.You ar... |
Why are Snowden's NSA leaks not all published at the same time (or close together)? | People forget. We'Re getting bombarded so much information everyday that we can't keep track of everything. If all the info were released it would be Big for a few weeks than die because some new scandal happened, like Russia invading Crimea. Everyone would forget what happened last week. |
Why is liquid water so hard to compress | The Bulk Modulus gives a compressiblity of 46 x 10^-6 per bar/atmosphere. The density of solid water is less than liquid water at similar temperatures, so you can't compress it into a lower energy structure. |
If cockroaches are able to survive nuclear radiation,what the hell do they put in anti-cockroach sprays like Raid? | This has been answered on here many times, but the simple answer is: * Raid is an insecticide, a chemical weapons that targets insect nerve systems. It is specifically tailored to bugs. * Invertebrates in general can handle more radiation than large mammals, but they do not have an infinite capacity for radiation. Cock... |
What is the disadvantage to taking on debt, when you can seemingly KEEP taking on more debt to pay your debt, until the day you die? | People will stop lending you money. They'll stop pretty quickly if you're taking on debt to pay debt. Then they will take your house and car and possibly children and kidneys. |
Why barbed wire fences face inward (toward the property), rather than outwards. | Think about climbing something: which part is easier, going up or going down? Now if there's barbed wire on the way up, it's easier to see and avoid. But on the way down |
Why are most pens blue or black ink? Shouldn't they just all be black, or was there a reason that blue became popular? | I'm not sure this is the main reason. But having blue pens makes it easier to tell if a signed document is the original compacted to a photocopy.I have a vague recollection of reading somewhere that the first ballpoint pens, which became popular during the second world war, were only available in blue Blue is used to i... |
How do objects with different masses fall at the same rate of acceleration? | They do, a bit, because of air resistance. A heavy object can push air out of the way more than a feather or piece of paper. But if you take away air resistance they'll fall at the same rate. This is because heavy objects have more inertia - it takes more force to move them. But gravity also pulls harder on heavy objec... |
Do animals (of any kind) recognize or understand music? | Not in the same sense that we humans do. Remember that Music is the result of thousands of years of art. Humanity is the only known species to have developed art as an expression of speech. Animals recognize the sound, they feel the beats, but they don't draw connections to them. That being said, some animals do respon... |
Why does sand + heat = glass? | It's like taking ice cubes out of the freezer, leaving them in a dish on the counter for a day, and throwing them back in the freezer. The crystal structure completely reforms in the water, making one transparent piece of ice. The difference between glass and volcanic rock is then analogous to the difference between wa... |
The difference between 1080i and 1080p. Which is better for gaming? | Progressive, always. Interlacing was used by television broadcasters back in the days of analog to save bandwidth. The power cycles at either 50hz or 60hz depending on where you are in the world and in order to match that the frames have to be the same. But a large amount of movie content was 24fps. They sped this up t... |
What exactly is going on in the brain/body of someone under anesthesia that makes them unable to feel pain and wake up at a very specific time after surgery? | It's not like you get a single dose and you're out for a fixed period of time. Anesthesia requires a continuous stream of drugs into your body. The anesthesiologist is a specialized doctor that monitors you the whole time and makes sure that you both stay under and stay alive. You don't come to until after the procedur... |
In ancient times what would people do if they didn't have glasses but needed them? | That's why its called Survival of the Fittest. The weak and unfit die out. It might be more common today due to technology and eye strain or it could be that people need glasses for stuff that they didnt need before. I mean I need glasses to read the license plate of the car in front of me or to see the sign to make th... |
why we only feel like we've gotten better from viruses after sleeping? | When we sleep our bodies release waves of white blood cells. They find things to fix while we sleep, and many more are released when we sleep in complete darkness vs with a lamp. I'll try to find the study I read to back it up! |
If water causes electric circuits to short and our brain is just one majorly complex electrical circuit, given the wet environment of the brain why isn't the brain constantly short circuiting? | The heart of the matter is that , neurons [brain cells] communicate with each other with chemicals, not electricity. The actual electrical signals produced by most cells are small enough that they do not overly effect nearby cells and are used to transmit signals along the length of a neuron, not between neurons. Myeli... |
Why does there seem to be so few homeless women? | In the US, there's a welfare program called TANF , which you can get only if you have a child. Since women are much more likely to be single parents than men, they're much more likely to qualify for this program, and this makes them less likely to be homeless. |
Why Do Men Grow Bald And Women Don't? | balding is mostly an hormonal issue. Free testosterone accumulate on the base of hair follicles making them weaker. The follicles on the top of the head are more sensitive than the ones on the side and back. Women suffer from hormone induced baldness but it's more distributed and less frequent than men. |
Why is it a legal requirement that you wear a seat belt, yet people are allowed to drive motorcycles? | > the only real safety measure on a motorcycle is a helmet, which at 70mph is not likely to do shit. Not true at all. Even in high speed accidents a motorcycle helmet can save your life. Remember it's protecting your brain, your most important organ! You can break every bone in your body and walk again, but if you inju... |
Why doesn't every post office employ a drug sniffing dog to catch illegal drugs sent through the mail? | Not only does it cost a lot to train the dogs, but you also have to have someone to care for them and someone to know how to work with the dog and understand when it's found something. |
How is it that Netflix has no content rated lower than, say, 2.5 stars by users? | I've seen stuff with less than that. Gotta look in horror flicks. The stupid spoofs are always rated terribly |
Why do humans moan while having an orgasm? | Communication. We're very social animals, we're built on communication. And sex for humans is, more than any other animal, a cooperative, mutual experience. So we want to communicate our pleasure with our partners. As well, it may have to do with the sudden relaxation of most of our muscles during climax combined with ... |
Why can I eat raw fish but not raw chicken or pork? | I can get chicken sashimi here in Japan, but the chickens are very clean and the slaughtering process doesn't contaminate the meat like in the US.I haven't tried it , and it isn't that common, but it isn't unheard of. I can also find raw horse raw beef, whale, and pretty much anything else from under the sea. |
Why don't people get caught pirating? | same reason why there's 100,000,000 pot smokers and very few get caught. cops have better things to do. well at least the cops that aren't handing out traffic tickets", 'Because it costs money, time and effort for each one. Those you hear about got "lucky" and thats why they were sued. More to make an example out of. T... |
Did monks and priests really drink nothing but beer in the middle ages? | Most people did. Water wasn't considered safe to drink, and was often contaminated with human waste. |
Why didn't evolution give us the ability to regenerate limbs? | It isn't able to regenerate limbs, but the human body is actually incredibly effective at repairing itself. If you break a leg, as long as you keep it still, and don't keep rebreaking it, it will mend itself. If your body gets attacked by a virus, your body will study the virus, learn it's weak points, kill it, and the... |
How did Einstein come to the conclusion that gravity is the bending of space and time? | People are explaining how it *is that*, not how Einstein *decided it was*. He had an aesthetic preference for geometrical explanations of physical phenomena, a temperamental belief/hope that shape is fundamental. In the case of gravity his prejudice turned out to be right, or at least justifiable—or at the very least m... |
Why are car engines more commonly located at the front of the car rather than the back? | Yes. Mostly less room for people. It's also cheaper, because you need less drive-train parts if you have a front-wheel drive car. If you have a rear-engined, rear-wheel drive car, it is very unstable without a lot of engineering. Mid-engined cars are inherently very stable, but lack much practicality for every day use,... |
How is it that wild animals seem to do fine without having their claws or hooves trimmed while domesticated animals need it done regularly? | Animals outside walk on rougher surfaces than their domesticated counterparts. If you cat uses it's claws regularly to escape predators, they don't need trimming. Lounging on the sofa all day, not so much. |
There were many search engines prior to Google, but Google became "THE" search engine. Why? What made it so much better than all the others? | Multiple Reasons: 1. Reliability: Google was more reliable than most search engines at the time. It found more relevant results and often returned what you were looking for earlier. It was also more reliable for web-devs to get their content to show up on google than other search engines.2. Usability: Google was the on... |
What are the non-religious reasons for opposing gay marriage? | * the gov't has in interest in supporting traditional, children producing marriage* homosexuality is a psychological disorder, not a lifestyle, and the gov't should not support it* gay unions are fine, but that's not what the word marriage means, so that word should be reserved opposite sex couples I don't want to sugg... |
Why cars only have 6 gears while bikes have 21? | Too many complex answers. Here's the simplest: Humans can't create as much torque as an engine. If you could put out 180hp & torque you wouldn't need gears 1-7 on your bicycle. |
Being unbiased - Can someone explain how Obama has done as a president LI5 | It's done probably the best he can. There are a lot of bullies/mean people in the government who want to stop him, even if he's trying to do what's best for the nation. |
Why can receipt printers only use thermal paper? What's the difference between receipt printers and regular printers? | Receipt printers use thermal paper because it simplifies replacement and means that you only have to replace paper. Your local 7-11 can't bother with having an IT staff to maintain the devices. Thermal paper simplifies the process.Thermal reciept printers do not use ink. Instead, the paper is designed so that it darken... |
Why does some antivirus protection software (Norton, McAfee, etc.) make your computer run worse than it did before? | Two reasons: 1. the job of antivirus software is to detect viruses. it is not to make your computer run faster. So they don't care about how much they slow down your computer. And in order to detect viruses, the AV software has to do a lot of work. Everything you send and receive over the network has to be scanned. Eve... |
What it takes to establish a sovereign nation | I don't know about international laws, but the risk is the chance of a neighboring country swallowing your nation up. All land is accounted for around the world, the possibility of any group of people seceding from a nation is slim. Remember in the US it has been attempted before and the government wouldn't allow it, a... |
Why america are so angry at their government, but don't seem to do much about it other than complain online. | Quite a few reasons: First, there is still plenty of scope for the American government to be changed by peaceful action, it's pretty amazing how many people here are involved the politics of their local cities and state representatives. On any given day there are thousands upon thousands of proposals put forward from t... |
Why do spicy food's "heat" stay in your mouth for long periods of time after you eat it when other flavors don't? | The heat from spice isn't a flavor, it's a sensation and the culprit is a chemical called capsaicin, peppers evolved the chemical as a self defense mechanism so mammals wouldn't eat them, part of that was hanging around so the animal learned the lesson. The oil that makes up capcaicin is not water soluble, so your mout... |
Why do so many jobs just require a degree. Without specifying which one? | For the most part, all degrees/diplomas require you to take certain courses. Math, English, History, etc are all courses that many colleges and universities make you take in your first year. Just to make sure your education is well-rounded. These tend to be the courses that the military, police, etc need you to have ta... |
Why are the English and French languages so similar? | They aren't! A few words are similar because English took some words from Latin and French. French is more similar to Spanish and Italian than it is to English. |
Is the nutritional value of a newly hatched chick the same as that of a freshly laid egg, since the chick can't gain any energy & energy can't be destroyed? | The chick has consume the nutrition from the egg and used it to convert into movement to peck itself out of the egg converting into heat and sound, which is dissipated into the environment. That energy isn't part of the chick anymore. |
Presidential term limits in cases where the VP becomes president. | This is, luckily, something explicitly covered in the 22nd Amendment: * You may not be elected as President more than twice .* If you take over as President for someone else for more than two years of their term, that counts as a term for you, so you may only be elected as President once. John F. Kennedy was assassinat... |
Why is inbreeding bad/prone to mutations and birth defects? | A gene can be either dominant, or recessive-- and they come in pairs. . If a recessive gene is paired with a dominant gene, the recessive is ignored and the dominant one is used-- let's say for instance, the ginger-hair gene is recessive and the brown/brunette hair one is dominant-- children born in this case would hav... |
How do radioactive substances poison humans? | Radioactive substances release high energy electromagnetic waves or high energy particles like alpha-particles . Both of these things can harm humans, by permanently damaging a cell, so that it can't function normally. If you are bathed in gamma rays, so many of your cells will be rendered useless or killed, and you wi... |
how does this ice bucket challenge actually benefit the ALS community? | The idea of the challenge is if you do the challenge you send them $10, if you don't do the challenge you send them $100. In both cases you send the challenge on to more people. Getting everyone in the US to send a charity $10 is a huge amount of money.It brings awareness. How many people are now more aware about ALS a... |
Why is everyone so upset about Abercrombie and Fitch having a target demographic | It's not really that A & F is only catering to this demographic but rather how it is alienating the others. CEO Mike Jeffries has openly announced his disgust with anyone who is 'not good looking' and not liking 'fat girls'. He didn't have to do this and I feel if he didn't, this wouldn't be an issue.People got their f... |
How is it that dogs get along well with humans? Is something biologically ingrained in their genetics? | Dogs were one of humanity's very first domesticated animals. They could help herd livestock, catch game, and provide protection. So over the centuries humans have bred them to have a slavish devotion and obedience to us. |
I tried a dog treat and it was really dry and tasteless. Why do dogs like them so much? | Dogs are known to sometimes eat their own vomit or feces. Taste apparently isn't a word in the doggie dictionary. |
How is math used in programming? | It depends on what you're trying to achieve. Programing does everything on your computer and a lot of things can be done with it so you'd have to be a bit more specific. If for example you're drawing an object onto the screen then you'll need geometry to map the object. If you want to then rotate/scale/flip/transpose t... |
Why do American college/university campuses appear to be leaning politically left? | There's an old saying, 'If you are under 30 and not a Democrat then you have no heart. If you are over 30 and not a Republican you have no brains.' We all are hit with socialist ideas and agendas from the 1st day of school, elementary school all through our college years. Then we are pushed out to live life on our own.... |
How does anybody know if a gold bar is a solid gold bar, and not just a gold-skinned similar metal? | One reason gold has been a standard store of value is there aren't many similar density metals . There are occasionally rumors and very rarely actual cases of [tungsten salted gold bars]. Tungsten is a good metal to use, because its similar in density . For those who are concerned, assays of suspect gold can be purchas... |
How does a baby chicken know there exists an outside world to break out of its shell into. | It doesn't. It is no more able to _not_ break that shell than you are to stop and restart your heart. It's just what the chicken does. |
Could you explain me why this type of infographics are trusted? | This is just my plausible speculation: The production and distribution of high quality printed materials required high cost businesses that would consider the value of their reputation before publishing anything that might damage future sales. They would employ editors and fact checkers who would filter for you. Recent... |
Why we instinctively clench our teeth/jaws when exerting force | so if you slip, or if you are engaged in combat, you won't dislocate your jaw or bite you tongue off if something hits your face. Stone age humans who clenched their jaws during fist fights probably had a better overall chance of getting laid than those who who didn't . You're the descendent of the humans who fucked th... |
The moon is one light second away from the Earth, does that mean if I am viewing the moon from a telescope I am seeing 1 second in the past? | Yes you are actually looking at the Moon 1 second in the past. It seem so unnatural for us because the distance we usually work with are so small that what we look at pretty much happen instantaneously. But at longer distance, the time it take for light to reach us is pretty important. A star a thousand light-years awa... |
Why do people who live in different countries keep their native accent long term, for example Arnold Schwarzenegger? | In the specific case of Arnold Schwarzenegger, the accent is deliberately maintained. Arnie's accent is so iconic and tied to his public image that he deliberately maintains it by working with an speech coach.Languages have their on uhh "infliction". I speak two languages and have been speaking both all my life for alm... |
How can we have the technology to complete safe assisted suicides but lack the technology for 'safe' lethal injections? | The medical establishment makes it difficult for governments in the US to access drugs and expertise that could humanely end a person's life. The result is that for executions US governments rely on incompetent individuals using increasingly experimental cocktails of drugs that often result in extreme suffering whilst ... |
Why does it seem like less people are interested in working now than 10 years and even 20 years ago? | Nobody *wants* to work. This has been true in every age. Certainly, there's satisfaction in producing something and seeing the fruits of your labor, but even then anyone would rather do that on their own terms than be forced to do it to survive. The difference now is that, thanks to automation and other advances in tec... |
WHERE does the body generate heat from? | It's a side effect of the exothermic chemical reactions in your body, like when cells break down ATP for energy. It happens in most cells in your body, but most of it comes from the major organs because they are always doing work. |
If chemotherapy targets fast reproducing cells like those of cancer and hair, how come people (who undergo chemo) don't lose their nails as well as their hair? | We do. I lost 3 toenails during/after chemo treatments last year. That was not on the list of side effects I'd seen, so it was a surprise. |
Why do cop cars have the small hub on the wheel instead of the entire rim or hubcab? | Doing a bit of googling, the consensus seems to be because hubcaps fall off when you drive aggressively and cops do that a lot. Better to have hubcaps that don't fall off so they don't need to blow money replacing them.To avoid valve stem damage. This was answered on "Car Talk" some years ago. Police cars risk losing h... |
What is Linux/Unix (in under 3 sentences?) | Unix is an old operating system like Microsoft's Windows. Linux is an OS built to work like Unix without violating any copy right in the process. Linux is free and everyone can make their own version of it as long as it stays free. |
I live in a big city, use public transportation and public spaces all the time. Should I be concerned about Ebola? | No, why because there have only been 3 cases of Ebola that could have spread in the USA. The total population of the USA 318,912,000, so 3 / 318,912,000 * 100 = 0.000000009406 % chance that you will be infected with the virus. I wouldn't be too concerned if I were you. |
How is it that a season of a show like Game of Thrones can be produced in a year, but a 90 minute movie takes multiple years to film? | Smaller films take 4-6 weeks to shoot. Big budget films may take 3-6 months. But there is also extra time for pre and post production work, marketing, and targeting a specific window in the studio's release calendar.
