How do pain killers target certain areas? | When you experience pain in your body, the nerve endings send pain messages to your brain, and painkillers effectively interfere with these messages at either the site of the pain or in the brain or spinal cord . The painkillers basically target your whole body but only effect the pain messages, whereby blocking the pa... |
If gravity can bend light and distort images, why isn't earth's (and other planets) images distorted when we look at them through a telescope? | Because it takes a whole lot of mass to significantly bent light. We can see when looking at the stars near the sun during a solar eclipse, because the sun is quite massive. We can't see anything when looking at other planets or moons, since they have a lot less mass. You can look at really massive objects through a te... |
How do moles (nevi) start growing in your skin? What makes them stop growing? | I come from a family of fair-skinned and acne skinned people. There are three signs to be aware of regarding whether or not a mole is cancerous: 1) it's bigger than a pencil eraser head 2) it's irregular in shape and 3) its more than one color. There are also skin growths called Seborrheic keratoses that are noncancero... |
Why do some charging cables charge faster than others? | There's two distinctly different things here: the charger and the cable. First, the charger. All chargers will be designed for the same or similar voltages, in the US 110-120 Volts AC in, 4.7V - 5V out. The difference will be the current output, an iPad charger will output a higher current than an iPhone charger. In fa... |
How do Radio Waves work? They have always been around? | Radiowaves are a form of electromagnetic radiation. This means that they have 2 components, an electric wave and a magnetic wave . Radiowaves are just EMR with really long wavelengths and thus low frequencies. Increase the frequency and you will get microwaves, do that some more and you get infrared waves, some more an... |
Why do whales, as big as they are, only feast on small sea critters? | First, that's not true, sperm whales eat squid. As for why the absolute biggest ones do not near large animals, well there are not that many large things to eat, and when you are really big, it's hard to be agile and catch smaller things. For example a blue whale can eat 8,000lbs a day, it's hard to catch that much foo... |
how paul george can snap his leg in half and recover to be an mvp candidate but people are wondering if KD can return from an Achilles tear? | A muscle tear is harder and longer to repair than a broken bone and is much more likely to happen again. A broken bone usually happens by a freak accident, which is unlikely to happen again. At least I haven't heard of a player breaking his arm/leg in the same place twice, but players reinjure their archilles, acls, et... |
Why does a punch to the chin knock one out but a punch to the head might not? | Hitting the jaw throws the head back and snaps it forward. This is because your neck acts as a leverage point, increasing the applied force, kinda. If I punch you in the forehead your head isn't going to move as much, as fast, or as forcefully. This applies to striking the back of the head and, to a lesser extent, the ... |
If we've never discovered life outside of Earth, what does it mean to say we've "discovered organic compounds" on a meteor? | When something is made out of lego it's recognizable as that thing. A castle, a boat, a spaceship, whatever. A single lego brick is also recognizable. & #x200B; Life has pieces too. When those pieces are found it means that life could exist using those pieces, not that it necessarily did, just like if you found lego ly... |
How does IT block thousands of websites with the click of a button instead of having to manually type in all the restricted sites? | Most companies don't create the lists of sites that are blocked themselves, but instead buy a product that comes with a list and even a subscription to updated that list of sites that they may want to block. These lists just need to be enabled by the company to block everything on them. IT can add sites that are to blo... |
I've always heard that not eating breakfast is bad for you, but what are the actual consequences if you skip breakfast? | Skipping it entirely is a risk[ factor for metabolic syndrome], according to some studies. There's a lot of hypotheses, but nobody *really* knows why. Observational and retrospective studies demonstrate this pretty well though, showing it to be related to [Type 2 diabetes], [coronary artery disease, and hypertension.] |
Earth's magnetic field is huge. What stops our metals from slamming into the ground ? | Earth's magnetic field is huge, but it's also quite weak on the surface. Enough to spin small pieces of metal, but the effect on other metals is small. The magnet part is only the core of the earth and there's thousands of kilometers of solid rock between there and the surface. It's like wrapping a bar magnet in a thic... |
After seeing a little spider dance to itself in the mirror, it made me wonder; are humans the only animals who are able to recognize that it is themselves in the reflection? | _URL_3_ magpie knows itself. _URL_3_ elephants Certainly most primates, so many videos I wont link _URL_3_ dolphins So no, but it tends to be more complex animals. Many can see 'similar animal' but behave like that animal is a threat . Most likely your spider was trying to mate with, or intimidate, what it perceived as... |
How do satellites distinguish between all the billions of signals emitted by all the devices in the world? | Satellites work on certain frequency ranges that differ from those used by most devices on the ground - usually satellites use higher frequencies and don't overlap to much with those used on the ground. Additionally, most of the devices on the ground are not even close to powerful enough to send a signal that could get... |
How exactly does someone die from drinking too much water? | Hyponatraemia. You get brain swelling because water begins to make cells swell. This isn't a problem elsewhere in the body because your body can expand, but in the confines of the skull, the brain has no room to expand. It therefore begins to increase in pressure as the cells swell, causing brain damage and possible de... |
How does grass make pollen? | I mowed a little over a week ago and my lawn is sending up flower structures already. Pensacola bahia is a type of grass that's notorious for putting up flowering stalks only hours after being mowed. Unless you mow almost daily in some parts of the world, your grass is going to flower. Another component to this is that... |
Why is it easier to learn a new language when you are younger and harder when you are older. | There's a concept called neuroplasticity at work there. When you're young, you're learning a lot, creating new associations between sounds, objects, and words. Those are formed as actual neural connections between areas of the brain. As you age, a lot of the connections are already set in place, and forming new associa... |
why is burning plastics (like polyethylene) bad when it's a hydrocarbon like wood? | Carbon, Oxygen: Not bad for you. Carbon Dioxide: Not bad for you except at high concentration. Carbon Monoxide: Kills you Being made of the same elements doesn't mean a compound behaves the same. |
What do businesses use the app “Looker” for? | As far as I can see, it's just a data modelling helper. It wouldn't just be setup to read from sql; in an app like this there would be a million different dataset types you could read. Companies use it probably because it makes data much more interpreted to those who prefer visual graphics to quantitative data. |
Why are there so many sign languages? | Historically, sign languages evolved with less communication between people of different areas. For example, Australian sign language is similar to British Sign Language because Australia was primarily a british colony so the deaf people brought their sign language with them. Over time, language changed, new signs were... |
If you are overweight, why can’t you live off of your fat preservatives and function normally? | You can, [Angus Barbieri went 382 days without eating. ] - although he did get medical supervision and o don't think anyone would recommend it.people have lived off just their body fat and they only feel uncomfortable for less than a week till the fat starts getting digestedPerhaps bears do get nauseous when they hiber... |
my mom has brown eyes and my dad has blue eyes (with slight heterochromia) and i have green eyes. how did this happen? | Your mom has a recessive blue eye gene and a dominant brown eye gene. You happened to have gotten mom's blue eye whereas you siblings got her brown eye gene. |
Why do all mammals have two eyes, but specific insects and arachnids have more? | Insects have different sight needs than humans and other mammals do. They tend to 'see faster' so much so that a congruent vision for them only starts to form at about the moment when humans are unable to discern any more frames per second. For insects, seeing quickly is far more important than seeing with a lot of dep... |
Why do so many ancient cities, especially the big ones, have dissapeared geographically after being abandoned? If nobody destroys them, shouldn't the structures and general architecture remain intact? | What cities are you thinking of specifically? Most big cities are at that specific place for a reason, usually they're crossroads for trade routes or defensive positions. Big cities rarely get abandoned entirely. But abandoned cities are all over the globe. Just from the top of my head. Macchu Picchu in Peru. Petra in ... |
What would be the real dangers of putting water on a nuclear meltdown? | They drained the water but installed a heat exchanger. Water exchanges heat very well but what you don't want is the water vapor to take tiny radioactive particles out to the atmosphere where it can be deposited somewhere else. There was a book about the Rocky Flats nuclear trigger facility where they had a fire and at... |
if a nuclear war would produce an ecological catastrophe, why hasn't nuclear tests produced it yet? | This question gets asked on here a lot. * Most of the bombs were tested underground * Those that were aboveground were often in deserts or oceans, not in places where burning would take place, and set off in isolation from one another As for whether there would be an ecological catastrophe in a nuclear war, the norther... |
Why can't we use materials with lower boiling points to generate power? | > also understand that according to thermodynamics more energy can't be gotten out of a system than is put into it, but shouldn't the turbines spin just as fast no matter what gas is being passed through them/what temperature that gas is? this is correct, in fact the boiling point of the liquid used is irrelevant for t... |
Why, when you swat a fly mid-flight, it seems unfazed and keeps flying? If an airplane got smacked by a giant hand while flying the plane would be destroyed wouldn’t it? | The fly has very little mass, so even when it's moving it doesn't take much force to stop it or change it's direction. The fly simply does not absorb very much energy when you hit it, or transfer much energy to your hand, so it's unharmed. In the case of the airplane, it has a lot of mass, so the force needed to bring ... |
What's so bad about corn? | Corn accounts for a huge percentage our crops. Especially breeds that have been designed to grow quickly, withstand pesticides and need as little space as possible. When you rely on a single crop so much, you run the risk of having serious problems if a disease develops that targets that specific breed. It's happened t... |
Where does food/drink that “goes down the wrong pipe” go??? | It comes up when you cough. If it didn't, you would end up with an infection, likely pneumonia. As for dust and other small debris, there are hair like structures that move in a wave pattern to push the dust containing mucus pit of your lungs where you either cough it up or swallow it |
Why does the the brain ignore the 2nd "the"? | It took me way too long to figure out what the hell was meant in this question until rereading the question several times and finally noticing the second 'the' in the topic. Wow. |
What is that 0.01% of bacteria that disinfectants can not kill? | It's a statistical percentage that exists solely to remind you to search the sub for questions that are asked repeatedly.The 99.99% number reminds me of my grand-mother when I was young and told me to never pretend being " the best " at something. Because you are always 1 variable or 1 random case away from losing. |
What does the SPF number on suntan lotion mean?? | Skin Protection Factor represents how many times longer you can stay out in the sun **if you completely follow the directions about applying and reapplying**. For example, if you were extremely pale and sunburn in 10 minutes under the sun, using SPF 30 properly will allow you 300 min under the sun before you get to tha... |
How is the Universe expanding, but it's not expanding *into* a larger containing space? | Imagine that our universe is a bubble of air underwater, and it is rising to a lower depth. In this analogy, the bubble expands due to the lowering of hydrostatic pressure. We don't know exactly what the water is in this analogy neither if there are other bubbles around . What you're asking, whithin this analogy, is ho... |
What the Bosnia/Serbia/Croatia war of 1992-95 was all about | Well no one was satisfied. Croats and Bosnians wanted their own countries since they felt that Serbs had way to much power. The current leader of Serbs at that time was Slobodan and he had a power trip. The way Yugoslavia worked back then was that each republic or autonomous province had one vote. There were 6 republic... |
Where does this "neutron" come from that splits U-235 / U-238 / PU-239 | Just to put a number on it: the spontaneous fission rate of U-235 is about 0.7 neutrons per kilogram per second, and for U-238 it is about 15 neutrons per kilogram per second. That's enough neutrons to start a chain reaction if you have any appreciable amount of it in one place in a critical configuration. That's why y... |
How is it that people who committed crimes that are no longer illegal, are still imprisoned? | Those people still made the decision to break the laws at the time. I don't necessarily agree with people being sent to prison for marijuana possession, but the laws are the laws and deciding to break a law carries the risk you will be punished. Perhaps they should be let out now though, especially if their only crime ... |
What happens to a glass of water when left alone for a night? What makes water taste "stale"? | Depends if it's covered or uncovered. If it's covered it's as good as bottled water. If it's uncovered, bacteria and dust in the air will settle down on the top layer and sink in. |
Why do people say mic check so frequently even if it works the first time? | If they are doing it right it's to check all the settings on a mic. For example is it picking it up from far enough distance. The other thing they should be doing is changing the pitch of their voice. To make sure the sounds mixer is not distorting or 'peaking out' that crackle you hear sometimes on higher pitches or o... |
What is Condensation and why does it stick to windows? | Air holds water. Most of the water is broken up so tiny that we can't see it. Warm air is spread apart more than cold air so it has room to hold more water. & nbsp; The air up high is colder than the air by the ground, so it pulls together and leaves less room to hold water. This makes clouds, which are just like fog b... |
How do fish survive when lightning strikes a body of water like a lake or pond? | Lightning strikes hit the surface of the water and radiate outwards along the surface. It does not penetrate very far and therefore the fish aren't really affected. |
How do animals with large antlers like Deer and Moose get through the forests without getting tangled constantly. | Moose and deer, and most animals with antlers, only grow the antlers during the time they are needed for fighting other males and displaying power to females. They shed the antlers in the off-season to make it easier to get through the forest and away from predators. There is less foliage in the Fall and Winter when th... |
What happens to a Fly when they are exiting a vehicle window of a car that is going 60+MPH? | The fly's mass vs. it's surface area on that kind of scale would be such a negligible force, it would likely almost instantaneously halt in the air and just keep flying. Air molecules are much more of a force at that scale than they are at our scale.Ever stand right at the edge of a road with cars going by at 60+? You ... |
why recipes say you need separate mixing bowls for ingredients, when in the end we mix all contents together? | Other answers are good, but there's more! In some cases, starches will clump together when they get wet. These clumps will not separate into the mix. So, instead, you mix dry starchy things together with other components like the sugar, salt, etc. The starch grains get evenly distributed into the dry ingredients, so wh... |
why does the feeling of needing to go to the bathroom come and go until it’s unbearable? Why don’t we have to go right away the first time we feel it? | Because your body is designed like this, the bladder first gives you the urge to pee at around 50%. Sphincters is your bladder respond to the amount of pressure it is under and when it gets too much they will invoulentarily release. So the first 'i need to pee' feeling you get in not really urgent. |
What is the benefit of doctors and nurses in hospitals working shifts longer than 8 hours? | Nurse here: don't make me go to that place more than three days a week. Also, the way they staff nurses, there's no way we can get our work done in 8 hours. Charting my work for one patient can take 45 minutes to 1 hour and 15 minutes total throughout the shift. |
How do bullets fired into the air come down fast enough to do damage? | > what makes it go fast enough to kill someone? Gravity. Their terminal falling velocity may be a lot lower than their muzzle velocity, but it's still well beyond fast enough to do serious damage or kill.Other situation is when bullets don’t go up at a steep enough angle to lose velocity and fall down. Instead they mak... |
How does Russia manage to antagonize much of the West when its economy is not much bigger than Australia or Spain??? | They have nukes, which lets them get away with much more than another country in a similar situation would be able to without having to fear retaliation. They also have all sorts of natural resources and raw materials in their really huge country which give them another bargaining power as an exporter. Also the rulers ... |
What are the criteria by which scientists decide whether a seismic event is a new earthquake or an aftershock? | You'd think it would be something fancy and technical, but no. In any related group of quakes. everything before the biggest one is a foreshock, everything after is an aftershock. The 7.x demoted the prior 6.x to a mere foreshock. |
Why are mobile game ads are so bad? | Because the games themselves are limited. If you look at PC game ads from late 90s, they're the same. Cool visuals with a tiny disclaimer that it's not gameplay footage. Cheap voice productions because the game itself doesn't have voice acting and they haven't set a style for it. |
How does a ski chairlift slow down for the people getting on/off, but the rest of the chairs in the middle of the ride up don’t feel it? | Well at blue mountain they just stop if for every chair. You don't feel it because it's barely moving anyway", 'Detachable Chairlifts will release their grip from the haul rope while in station, allowing more time for the passengers to get on/off, while maintaining a much faster speed between stations. Fixed Grip Chair... |
Why can firms like Ally & Goldman Sachs offer much higher interest rates for savings then my own bank? | Banks make most of their money from issuing loans. They're allowed to lend more than they have in cash, but they need to have at least some money to start with, so they offer savings accounts to get people to give them money to lend out. Then the Federal Reserve sets a requirement for the percentage of deposits that th... |
How does snake charming work? Is it legit? | It is a defensive posture on the part of the snake. The movement of the flute like instrument draws it's attention the snake is rearing up because it thinks it's another animal, possibly a predator. |
Why are printers in offices so huge when regular printers do a perfectly good job? | Regular printers don't do a perfectly good job when you print thousands of pages a day. They don't print nearly as fast, their toner cartridges don't last as long and internal components aren't designed to be serviced. If the transfer roller goes out in your small printer you're probably going to just get a new one bec... |
What happens to the brain when you zone out? | I'm a big day dreamer. I can just sit and stare at the tv or whatever and go completely offline in my own imagination, Making up some wild story in which i'm the main character. I do the same during slow periods in my work or bus rides. So it is also a great way to pass the time. But it also happens on moments i have t... |
How are hippos so fast despite their size? | They're extremely strong and fast but they have much less stamina than other animals, including humans . Different animal species trade stamina in exchange for explosive strength, just like you can train to last a long time using your maximum strength as opposed to training your maximum strength itself. This is pretty ... |
The controversy around the reliability of Wikipedia | The other comments have covered it well, but one other point to note is that English Wikipedia's editors [skew dramatically young and male]. That means that certain topics which appeal to those demographics get much more coverage and are generally sourced and edited much more heavily. For example, the main page for the... |
What is a good scenario to use the lower gears of an automatic transmission vehicle and why? | If you're hauling a heavier payload than the vehicle is designed for, and you don't want the automatic transmission to switch into high gear while you're on a downslope, only to struggle up the other side. Automatic transmissions often don't downshift as effectively as a human can with a manual– which shouldn't be surp... |
How was Venice built and how does it stay afloat? | It's not floating. It's built on a bunch of small islands separated by narrow waterways. So they built it like they would any other city, just with more bridges and canal routes connecting them. |
how do cameramen and women in films hide the cameras whilst filming so well when there is a scene with reflections? | Look at the actors eyes. You'll often see the lights. Otherwise, they shoot the same scene multiple times from multiple angles |
What is DNS over HTTPS? | Here's the deal . Right now your isp, gov and everyone in the chain between you and your dns servers can see what websites you are going to. Not the specific web page on that site, but that your on _URL_9_. Everyone's freaking out because if you do your domain name lookups over a secure https channel they won't be able... |
How does hearing help you with balance? | It isn't the hearing itself that help with balance, actually there's a liquid inside tubes, close to the inner ear, so the body measure your inclination based on the movement of the liquid |
what happens to the donors dna when an organ was transplanted or the blood was transferred? | Transplanted organs retain the donor's DNA forever. Most blood cells don't have DNA. The only exception to this is white blood cells, but they don't reproduce, so once they die, they'll be replaced by the recipients original white blood cells with their own DNA which are made in the bone marrow. If a person has had a b... |
Why does data stop working while calling? | The best I can recall from my days working as a salesperson for a cell phone carrier this does not happen for all carriers. It depends on your carrier and what tends to happen is that you are on frequency when you are using data. Calling and texting utilizes a different frequency and if your carrier doesn't have a seco... |
In Soccer, why do the US Women’s Team perform so much better than their Men’s team? | Because the women's game globally isn't as advanced as the men's and America spent money building the women's domestic quality before anyone else. In the men's game it's already the biggest sport in the world so its harder to win especially when its not your biggest sport. Women's games in England do well to get crowds... |
Is there any scientific reason why the US's shuttle launches were about as far East as they can possibly manage on their home soil? | They weren't as far east as possible. Maine is much farther east. Maine is the closest US state to Africa. Florida was chosen because it is south and on the coast. The ESA launches from Guiana in South America near the equator. |
why isn’t it possible to keep Great White Sharks healthy and alive, as all attempts cause the sharks to die rather quickly in a contained environment? | Technically speaking, you can tie a human down to a bed and feed him intravenously and supply him with a heavy dose of antibiotics to ward off sickness. There's minimal bodily waste due to the intravenous feeding. Just keep him in that bed indefinitely. You could theoretically keep him alive for a long while, but what ... |
Why does ink dry on a paper but not on a pen's tip? | Adding on to what the last person said. The ballpoint pen was a revolutionary creation. Before ball points you had Fountain pens which sucked ink into an internal well but still essentially wrote like a calligraphy pen. And ink was always a problem. If your paper was too thin the ink would bleed through to other papers... |
why do rockets need to take off vertically? | Short answer is they don't. Rocket is just a propulsion method. If you look at how some missiles and rockets fire off of ships they typically do it at an angle. As far as spacebound craft vertical is simply the shortest distance to their target", 'Rockets need to do 2 things. First, get up into space. Second get going ... |
why do companies care more about caxh flow than actual capital? | If your money is moving, it's working and working for you. Capital just sits there tied up in assets I would believe. Someone correct me if I'm wrong though |
Where does all the water go when the tide goes out, and how does it come back in? | It's on the other side of the earth . The tide is caused by the moons gravity, so it's high tide below it, it literally drags the water about As a further fun microfact, this means oceans are not perfectly level, you might be sailing 'uphill' ", 'It goes to the tide in on the other side of the planet??Thank you all for... |
Handbrake and brake pedal, how are they different? | Pedal is most likely hydraulic in some way, where the handbrake is mechanical. The handbrake isn't meant to have any steps in-between not engaged and fully engaged. The pedal is designed to be steeples and enrage on breaking at every point from not engaged all the way to fully engaged. Hope this helps.* Footbrake - all... |
Why does rain have a calming effect on people? | I'd love to know if there is some actual scientist research on this. I know there is some on ASMR and it's relaxing effects. Rain doesn't cause the tingling effect associated with ASMR, so it has to be different, right? |
the reflection on highways we see from a distance that disappears as we approach that point? | Do you mean a fata morgana ? Edit: Fata Morgana works simple: the air right above the road is way hotter than the remaining air above it. This heat difference causes a difference in densities . The density is proportionate to the refraction factor, which makes light change its direction when it travels from one medium ... |
How can someone tell what caused a fire if all that’s left is ashes? | Not all ashes are alike, and not everything burns completely. For instance, if you toss a book on a fire, the outside will char into ash, which is a good thermal insulator for the inside of the book. It takes a long time and a lot of heat to completely burn a stack of paper without moving it around, knocking the exteri... |
How is it that electrocution can kill you, but it can also be used to revive you from death? | It's worth noting that electrocution specifically means to put to death by electricity. It's a combination of the words electric and execution.Im not sure on the mechanics of electrocution. But afaik defibrillators dont actually restart the heart instead they kind of reset it. A heart attack is where the 4 chambers of ... |
why do cars take longer to start when in cold weather vs warm weather? | The engine also needs to be lubricated by the engine oil to function correctly. Colder oil is more viscous i.e. it doesn't flow as easily. With the oil being a lot thicker at lower temperatures this means there is more resistance inside the engine and that makes it harder to start. |
How does music invoke such an emotional reaction from us? (e.g. making us want to dance, cry or sing) | Although there isn't a clear answer to this question, there is some interesting research that suggests interpreting music uses the same neural pathways that interpret primal emotions . The theory explains, at least somewhat, why even isolated cultures use the same type of descriptions and metrics when explaining music ... |
How does music streaming work? When downloaded and when not downloaded? | Streamed music is downloaded to your computer, just like any other file you download. The only difference is that the file isn't saved, it's just downloaded into the RAM and then discarded after it's played. |
what made the modern Space Shuttle program so dangerous? | The way the shuttle is mounted - strapped to the side of the rocket, rather than on top of it like all other systems, is inherently more risky. With Challenger, a capsule system could likely have been pulled clear of the exploding rocket with a launch escape system. With Columbia, the heat tiles would have been protect... |
Why can cows and other animals constantly produce milk but humans cannot? | They don't. They only produce after becoming pregnant, and produce until the demand stops. This is true for all mammals. While a mother nurses, the draw of milk produces hormones which continues milk production. When she stops, these hormones are no longer released and milk production ceases.They don’t, milk supply eve... |
- why can cancer come back several times in the same person after they've been in remission? | You get cancer because something in your dna broke in a few cells that caused them to replicate uncontrollably. Remission means its either not growing or shrinking , but it doesn't mean its gone. If you are more prone to that sort of deterioration then it can happen again. If it has happened once it means something bro... |
- What is with the seemingly arbitrary scoring in tennis? Why does it go 15,30,40, Advantage. Why isn’t it all in increments of 15? | One popular theory is that it's related to a clock, the minute hand hits 15, 30, 45, then 60, so that's how they scored it. 45 got turned to 40 because it's faster to say 40 in French than 45 |
how eating charcoal / charcoal skin care is healthy | While it isn't bad for you I wouldn't say that it's necessarily healthy. Activated charcoal is just burned coconut so while you are able to eat it there is no real benefit. I'd liken it to eating burnt marshmallows, some people like them and they're not too bad for you. Skin care is just talking about how it's naturall... |
How are paintings proven real or fake? | You'd be surprised how much artwork is catalogued. Zervos made a catalog of 16,000 works by Pablo Picasso. So, when you find an uncatalogued pencil drawing with a Picasso signature in your grandmother's scrapbook, there is a lot to compare it to. There is still a process for determining, by comparison, if your sketch c... |
I know there are multiple roles to build a building, design and construction. What are the processes to get a building built? | 1. architectural design - this guy draws up the blueprints and specs of the building. it is a complete design, take this to any general contractor and they can build it.2. zoning - your type of building needs to be in a location where that type of building is allowed3. utilities - you need utility hookups which is done... |
Why do some countries use second-level domain country codes (._URL_1_ or ._URL_0_) and others do not? | Real answer? Be because each country can decided to use and divide their top level domain code however they want. Originally, there were only 7 top level domain suffixes - .com, .edu, .org, .net, .gov, .mil, and .int After the forecasted success and exponential growth of the internet, the TLDs were expanded to include ... |
How do fish swallow other fish whole and not get cut up from the inside by their sharp fins? | The inside of the stomach is very compacted and there's no flow of oxygenated water into it. As a result, the shark has little to no room to move to try to bite its way out and is dying of hypoxia. Meanwhile, the walls of the stomach are thick and lined with mucus that protect it against sharp fins. |
Why do antidepressants dampen emotions? | Our brains use a series of chemicals called neurotransmitters to transmit information between cells. when people have to much or to little of certain chemicals, it can affect how you think. One of the potential causes of depression is not enough of a specific neurotransmitter called serotonin. A lot of anti depressant ... |
What is the difference between an AWD, 4WD, FWD, and RWD? | FWD is front wheel drive, so the power is supplied to the front wheels to pull the vehicle along. This provides better traction in wet and snowy weather due to weight of engine between these wheels. RWD is rear wheel drive, so power goes to rear wheels to push vehicle.
