We get hungover because we are so dehydrated. But in the processes pf drinking my urine is clear. What is the process dehydrating me, making me hung over?
Ethanol inhibits anti-diuretic hormone in the body. This hormone promotes water reuptake, so its inhibition results in increased water release that is greater than simply the extra water you're taking in by drinking. As a result, you get dehydrated.
Why do some meals trigger diarrhea almost instantly?
Your gut is full of sensors, particularly pressure/pain and taste buds. When your body detects patterns of taste and gas and pain and pH and whatnot that it recognizes, it just says "Fuck it, I remember this stuff., get this out of here now". So while you can be allergic to some foods, there is probably a whole list of...
Are dead germs safe?
The "corpses" can be dangerous indeed in specific cases. It are usually not only the germs itself which cause problems, but toxins produced by the germs. Even when the germs are dead, these toxins may still be active and be a cause for trouble.
Why are we taught to walk across the street? Surely it's safer to run?
You're more prone to tripping when running, which would leave you prone, which is more prone to being run over.
Why is chocolate poisonous to dogs?
There's a stimulant drug in chocolate called theobromine. We can process it easily, dogs can't.
Is having sex with the flu, harmful?
I think this may help. 1. DON’T try to give a blowjob with a stuffy nose because you will suffocate. 2. DO try doggy style to avoid having to look at each other’s red, snotty, cold-medicine-drunk faces. 3. DON’T sneeze into your lady’s vagina or your man’s ballsack. If you feel like you might blow snot at any second, s...
Why does putting a Q-Tip deep inside your ear and rubbing it around feel so good?
You're basically scratching the inner wall of your ear, where dead skin constantly is building up in the form of ear wax. Dead skin buildup is thought to be a chief cause of the sensation of itch so what you're basically doing is gently scratching a tiny itch inside your head.Ive always got a wierd tickle in my throat ...
If skin sheds, what happens to the shedded skin of 7.2 billion humans?
Skin cells are a big component of indoor dust. Edit: NOT a big component, but still a small portion of dust.
What is the political situation in Russia?
Russia has a hybrid system, meaning that they have both a prime minister with a parliament, and a president. They have a constitution, which both describes the government and protects human rights. The president has a limit of two successive 6 year terms, meaning you can be president for 12 years, take a 6 year break, ...
Why do dogs like playing fetch with things? (Sticks, tennis balls, etc.)
It satisfies their instinctual urge to hunt something down and then pounce on it. Remember, wolves are powerful predators, and though we've bred most of that out of our cuddly friends, we can't get all of it.Dogs have hunter instincts telling them to chase and catch so that they can eat. As puppies they demonstrate thi...
What exactly is a "Demigod"?
"Demi" is French for "half". So anything that's demi-something is half something. Or \'not quite\'. A demigod is not quite a full god. Either someone who has one godly parent and one human parent, or a human who is so awesome that they 've almost become a god. Are they fictional? Well I guess that depends on whether yo...
Is it possible for there to be sun sized chunks of rock floating without orbit in our universe?
No gravity excludes the possibility. The chunk of rock you refer to would long ago have begun a process to become it's own sun. Darting around the cosmos. It would form based upon the composition of its environment into one of a myriad possibilities all of which we would call stars. The environment I refer to is not st...
What's the 'point of no return' for regenerating muscles and bones? If you loose a finger, that's it, but if you get a really nasty cut, most will heal.
The line is how much blood can get to the injured area. When you experience an injury, your body does everything it can to close the hole -- including replace functional tissue with scar tissue . A small cut can be healed easily since both halves generally stick back together and there's plenty of vasculature to supply...
How some materials conduct heat better than others, and how do heat-resistant materials work?
1. **A good heat conductor does not absorb a significant amount of heat as it is passing through, and therefore most of the heat is able to make it to the other side of the substance.** Yes it is generally a matter of the atomic type and structure. Compare the thermal conductivity of diamond at 2200 W/m/K to charcoal a...
the psychology of the "superfan" and why they have such strong emotional connections to their Idols?
Different reasons for different people, I think. Superfans of a sports team or a particular player likely have very fond memories of the sport, team, or player growing up, or fond memories of the connection they made with others through that love, such as with a parent, sibling, friend, etc. The team or sport or player...
If we exhale CO2, how does giving breaths to an unconscious person help them at all?
The average breath you exhale only has about 4-5% less oxygen in it than it did when you inhaled it.There is only a small amount of carbon dioxide exhaled. We aren't that efficient. We exhale 4-5% carbon dioxide and around78% nitrogen and between 13-16% oxygen. There is enough in what we exhale to provide oxygen to ano...
How do antibiotics destroy gut flora / lead to weight gain? How do you restore it?
Gut flora is just bacteria in your gut. Antibiotics kill bacteria, and they don't discriminate between "good" and "bad" bacteria. One way to restore gut flora is to [eat yogurt,] or other sources of [probiotics.]
how does a lumbar puncture dx meningitis?
As the disease progresses, confusion, coma, and seizures develop. These complications are due to HIE, increased intracranial pressure, and a toxic metabolic encephalopathy. HIE is due to shock. The toxic metabolic encephalopathy is probably caused by unknown diffusible substances that have a neurotoxic action The corne...
Why seeing something disgusting can make us vomit.
AFAIK this is an instinct; your body is saying 'do NOT eat this'. If you associate rotten food with puking, you will not eat the rotten food .Because a long time ago when our ancestors hunted and ate together, it wasn't known what food was ok for you and what wasn't. So if someone threw up from eating a poisonous berry...
Why is it that when I see something that grosses me out(like Trypophobia), I still want to see more?
Well one possible explanation that my psych prof explained in class once is that fear chemically is potentially addictive. When we see something that disgusts us or something that we're afraid of, the brain releases the neurotransmitter dopamine which provides an almost high type feeling in collaboration with feelings ...
how do they know the quantities of the nutrients for every food to put on the labels?
The ultimate answer is you can separate things out. You can centrifuse to separate things with different weights, you can burn things to leave unburnable things, you can add chemicals that react with certain other chemicals and then calculate how much combined. But in general you do that for simple ingredients instead ...
EIL5: How/Why the Republicans & Democrats ideology switched over time.
Think of a long stretch of beach, on this beach there are 2 ice cream stands on either side. The people are spread out evenly on the beach so they both get the same amount of customers. But one day one of the ice cream stand managers get a brilliant idea, by moving the ice cream stand closer to the middle they will get...
Is anesthesia the same for your body as sleep?
No. Most forms of general anesthesia stop essential reflexes to keep your airway open. Some may stop the breathing and may lower the heart rate and blood pressure in very dangerous ways. This is why anesthesiologists support your breating and circulation by various ways such as breathing tubes and machines, as well as ...
Why doesn't the TSA agent face criminal charges for lying in court?
I've wondered about this too. I have also seen a reddit post from a news channel baiting TSA agents with Ipads. TSA agents stole the ipads and then the news correspondents used an app to locate the equipment back to their home. What is going on here?
What causes intrusive thoughts?
My theory is that when we lived in the wild as cavemen we had to constantly be on alert for dangers and for things to eat. Our brains spent all day thinking about staying safe and finding food. Now our brains don't need to do that anymore, but the constant thinking hasn't evolved out of us yet. So our brains make up ot...
People with very high IQ (200+)
IQ is not a very good indicator of intelligence. Nevertheless, if I assume you just mean "extreme outlier intellect" then I could better answer the question. Perhaps the most famous example of a genius, Albert Einstein, had a brain that was physically different from a normal human brain. Our brains have "folds" and it ...
Quantum computing - what is it/how will it work?
At the moment computers use transistors. This means that when something needs to be calculated, it needs to be in binary. These 1's and 0's are convenient as electricity has two states, on and off.Qubit's on the other hand aren't restricted to using 1's and 0's. These atoms can shift 180^o on their axis, meaning each b...
Who coins names like ISIS?
The wikipedia page covers the name in some detail: _URL_0_ But essentially ISIS was an acronym for their name which is translated into english as "Islamic State of Iraq and al-Sham", al-Sham being another word for the "Levant" which is basically another word for the area around Syria. That's why the US government uses ...
how radiation can both give you cancer and be used in the treatment of cancer.
The difference between a cure and a toxin is often just dosage size. Radiation damages cells, causing the kind of damage that can cause cells to turn cancerous but that doesn't change the fact that radiation can also just straight up kill cells. It is sort of like how a knife can save a life or just as easily end it.
Why do photos of my laptop screen that I take with my iPhone camera look like tartan overlaid with a subtle wood pattern?
A monitor is not actually displaying one single image, it is two that running side by side. If you have seen references like 1080i and 1080p, they are referring to if the picture is interlaced or progressive scan. Interlaced displays are showing the odd and then even images. If you can imagine you screen as a series of...
. Why does porn seem so much louder than everything else?
Haha, paranoia. Basically the same feeling you gent when you smoke weed and swear that everyone knows. It's just psychology, you're most likely trying to be quiet. It's like opening a bag of chips during S movie. Loud as fuck, but really it's just the circumstance
How are Different kinds of medicines made?
The wanted antibiotic effect is a metabolite, small molecules found in the fungi. They are produced by 3 ways, fermentation , semi synthetic where you basically enhance it by adding functional groups or made synthetically, where you in step by step add the wanted atoms to the chemical structure. You basically supply yo...
How does putting a magnet next to a non magnetic object make said object magnetic as well?
[This video by Veritasium] does a great job of explaining it, the relevant bit is around 4:40 in. Basically if the material can be magnetic, but isnt, it's because it's not all alligned the same way inside, when you introduce a magnetic field, you can allign everything in such a way that it becomes magnetic. You can't ...
Why are there so many abandoned cities in China?
China has a problem; they have a lot of citizens and not nearly enough jobs to keep them all employed. One of their solutions has been to invest heavily in construction resulting in the building of cities for a population they just don't have.
What's the relationship between ongoing conflict in Mali and the allied intervention in Libya? How strong is the link?
Gadaffi used Malian Tuareg mercenaries, who went home after the war and used the weapons they got from him to rebel against their government.
what is common core testing and how is it different from other standardized tests? Is it as awful as I think it is?
I'll qualify this with "in my own experience" and "in my opinion." Source: I'm a current high school English teacher. The ideal of common core is just that - a common core. The idea that everyone needs to know the same things. That there is a fundamental base which everyone should have. In many ways, it sounds good in ...
What is the method behind the numbering of roads/highways?
"In the numbering scheme for the primary routes, east-west highways are assigned even numbers and north-south highways are assigned odd numbers. Odd route numbers increase from west to east, and even-numbered routes increase from south to north" _URL_0_', "It can depend on the location of the road, and the type of road...
How do orchestras know how a song should sound the first time they're playing it?
Do you know what the word "omniferous" means? It means "bearing many things". Have you ever seen or heard that word before? I'm going to assume you haven't. Do you know how to say it? Even though you 've never heard it pronounced? Of course you do. They know how to read music, just like you know how to read letters. **...
How is "Source Code" different from the software released to consumers, and why is it important?
Like you're 5 The software released to consumers is a cookie, and the source code is the recipe for that cookie. Without the source code recipe, you don't really know what's in the cookie, or how it was made. You can't change it or improve it. If the cookie has rasins and you'd prefer chocolate chips, you can't make yo...
Why is manga/anime, essentially comic books and cartoons, so huge in Japan?
The way it was explained to me is that there's a mentality in the United States, and probably most of the Western world, that most cartoons and comics were originally intended for and targeted towards children , a mentality that's only recently falling apart. Japan never adopted that mentality, and it's just as legitim...
Why does my nose run when I go outside in the cold?
When your body gets cold, it pumps more blood to the surface and extremities to keep them warm.* The mucus glands in your nose are blood-powered, and so more blood means more mucus. So your nose runs. By the way, this is also true of other glands. I wouldn't say this to a five year old, but among such gland examples ar...
Why do we sometimes wake up and not know who we are or what the hell is going on?
Sleep works in cycles that last usually an hour and a half. You can read more about it by looking up "REM cycles" on Google, but essentially, when you enter a cycle your brain is doing all kinds of stuff, healing, putting stuff back in place, etc, etc. And then after an hour and a half it exits this cycle, pauses for a...
Credit and good ways to build it
Credit - The more you have of it, the easier it is to get more. If you want a shiny new bicycle, but Mommy doesn't have enough money, if the store thinks she is a good girl they will give her the bike and let her pay for it later. The way they say she's a good person or not is called her "credit rating" and if it's goo...
When and how was the accepted world map model created? Was there a reasoning behind, for example, New Zealand being the 'official' rightmost country, or was it arbitrary?
The reason New Zealand is farther to the right is because it's about the farthest East you can from London without traveling more than 1/2 the globe. Why London? Because the British decided to use it as their starting point. It was basically arbitrary *to them* so London made sense. Eventually most of the ships in the ...
What actually happens when you pull your back? I mean the common back issue where you awkwardly pick something up or cough in a weird position and cause back pain for a few days.
Pulling your back is a series of events. Often the back muscles are not in proper condition, often due to a desk job or other health issue. Then those muscles may be under additional stress, due to activities, or carrying weight. Finally, the "straw that broke the camel's back" and the simple bending over to pick up so...
Why do a lot of bubbles form whenever I pee in the toilet?
Bubbles from peeing in the toilet can be caused in a few ways: * Your urine is composed of mostly water and concentrations of waste nutrients. When you're slightly dehydrated, you will have less water relative to the waste, which can then cause foaming when it comes into contact with the water in the toilet. If you dri...
How were hand-drawn cartoons transfered to newspaper printers before scanners were a thing?
This was one of my first jobs on my college newspaper just before we went digital using desktop layout . Photostatic cameras were used to take a picture of them on film, but at the same time they would, through the use of filters, turn the darker areas into a series of dots. At the same time they could be sized up or d...
what happens to my brain when I'm feeling "mentally drained"?
You need energy to fuel your brain, as much as you need energy to flex your muscles. When you run low on energy, you have less ability to make decisions, because your brain becomes focused on finding food instead of an abstract task. [Research Paper] [Great Lifehacker article] So have a light snack before tackling a co...
Why is it when we try to remove an impaled object from ourselves, it hurts so much?
Think of it as a cork. For example, a knife impaled into the abdomen will create a wound the exact same size as the knife. As the knife is removed, anything that was cut on the way in is no longer "snug" against the knifes blade . This is where internal bleeding becomes a big issue, and the reason that any impaled obje...
what is the difference between the north pole and the arctic sea?
If you picture the Earth spinning sideways, the north pole is the very top, the south pole on the bottom. If you were to somehow stand on the north pole, instead of spinning around Earth's axis, you'd simply spin in a very slow circle. The Arctic Ocean is simply an ocean that happens to cover the spot where the north p...
why is there two separate awards for Academy Award for Best Directing and for best picture? Why not just one?
The award for Best Director is for how the director brought the screenplay to life. The award for Best Picture encompasses everything, from directing, to the screenplay, acting, etc. No matter how good of a director you are, a bad screenplay is a bad screenplay and a bad actor is a bad actor. **EDIT:** Also, since it g...
Why is the speed of light the "universal speed limit"?
The "speed of light" is the speed of all massless particles. What makes them special is they have no mass. So all EM travels at the speed of light, and, in fact, all EM technically qualifies as light, not just the visible light people commonly think of. But, again, the "speed of light" is not reserved for only light, b...
In the English language why is there always a U next to a Q?
In Greek, there was a time when Q was generally followed by rounded vowels and by itself had an unvoiced K sound kind of like a hard G. Gradually, more and more of those sounds began to use the letter C, and Q only remained useful in order to make the /kw/ sound when combined with U. It passed into English by way of La...
How do nature documentaries get those incredible close ups of wildlife?
you use a hide, basically a tent that's dressed up to look like the surroundings and left there for weeks and months until the animals are quite used to it, then you hide in it, keep very quiet and just let the animals get on with doing their thing", 'They could be using remote cam setups some timesJust like hunting, o...
What happens to smells once they're "gone"?
smells are just vapor or particles in the air that react with our nose. When smells go away, whatever vapors or particles that were in the air causing that smell have spread out enough that it either isn't going into our nose at all, or such a small amount is there that we can't detect it.
How do birds all fly perfectly in sync with each other when in a flock?
Birds vision and reaction times are better than ours. They essentially see and hear the world much faster than we do. A bit like bullet time in games. Most birds also have a much wider field of view and can process a substantially wider range of colours. _URL_0_', "Same way human pilots do. The bird in front is the fli...
How do GPS satellites prove that general relativity is true?
Okay, so there's the two time-related effects acting between us and GPS satellites. One is special relativity, from which comes the effect of time moving slower the faster you go. GPS satellites are moving at some speed with respect to us, and, importantly, accelerating with respect to us constantly . So their internal...
Why do stores only accept plastic soda bottles for recycling? Are they made of more valuable plastic than other forms of plastic?
Because you don't pay a redemption value on other plastics you buy, even if it's made of the exact same plastic. If your soda bottle was made at the same factory as the ones who makes plastic containers for something else and you didn't pay CRV for it, then you won't be paid for it.
A fair tax/consumption tax (pros and cons)
A fair tax is essentially a sales tax. It is intended to replace other taxes in general and make it so that people are taxed based on what they consume. Statistically this would mean those who spend more of their income would be taxed a larger percentage of their income as those who do not. In the US legislation propos...
Why does synthesizing super heavy elements fail so often? Are the particles missing their target? Why isn't every hit a success? Seems pretty random.
You got it in one; it's pretty random. Particle accelerators are like firing bullets around the world, and trying to shoot one bullet out of the sky with another bullet. It's hard, because they are tiny, and moving very fast. Other setups might use something like Calcium 48 as the bullet, and fire it at a stationary ta...
EP vs LP vs Album. What is the difference and why does it matter?
Running time mainly. It was more of a thing when music was being pressed on vinyl. A single had 2 songs pressed on a 7" record and was spun at 45 RPM. An EP typically had 4 songs and was also usually pressed on a 7", but was spun at 33 RPM . Then there's the LP which was a full 12" record with usually 5-6 songs per sid...
Why isn't it mandatory for people to retake their drivers licence test every 5/10 years?
It's assumed that if you haven't gotten any major speeding tickets, been in any major accidents, etc. that you don't need to be retested. The hassle of retesting everyone would be an enormous hassle. Look at how crowded DMVs and DriveTest Centres are already. It's a cost-benefit kind of thing. If 1% of drivers are bad ...
What causes older computers to die?
One of the most common failures in a PC is the capacitors. Electrolytic capacitors are "filled" with a product that allows them to function, however long periods on non-use, freak reverse current moments, long periods of use, and basically farting sideways while not speaking the correct phrase in their presence can lea...
Why doesn't the placebo effect work backwards?
- I think you're overestimating the power of placebo effect. Normally, people won't get cured even if they have a strong belief they will. But sometimes a different outlook on a situation can change the way your brain works due to different, more or less complicated mechanisms, this is the placebo effect. For example, ...
Why do people go to college to major in business?
Going to college isn't just about learning from a textbook; if that was the case, you'd see a lot more people buying textbooks and reading them in their spare time and skipping the degree. A degree in business should:gives you a broad business background ensure that you specialize in one of the above so that you're mor...
Why do banana peels turn brown faster if you remove the banana?
Some of the primary culprits of rotting food are air, moisture, light, temperature, and microbial growth. When you remove the inside of banana, you open it up and expose the inside of the peel to the elements too. Increasing the surface area that is vulnerable to the elements will speed up the process, especially since...
Why does most articles in the internet tend to be cut by a 'Continue Reading' button?
Knowing that the person is actually reading the page allows higher advertising rates to be charged. I mean, if you were an advertiser, wouldn't you pay more for a page that had proof that it was being read over a page that didn't?", 'What the other guy said was true, and they'll also "double dip" on ads sometimes. Hitt...
Why is David Hasselhoff such a star in Germany?
Rewboss, a Brit living in Germany quite perfectly explained it in [this video]. Short version: He is only famous for one song "Looking for freedom" because that song coincided with the Fall of the Berlin Wall, and therefore the pursuit of freedom was a rather popular sentiment in Germany around 1990. Most younger Germa...
What does ISIS have against football/soccer?
Soccer is a western sport. Western *anything* is against Islam by ISIS's theory of *how Islam works*. That's really it. Saying *because they're crazy* is a legitimate response when *they are crazy*. ISIS is doing things that even *other* Islamic extremists think is *too extreme*.Well I'll give you an alternative answer...
In the Marvel Superhero world, why do the Avengers not always work together?
Because most of the Marvel movies happen at either the same time or very close together. I remember during Iron Man 2, Phil mentioned something about going to New Mexico, which is where Thor's hammer landed , making IM2 and Thor have a small amount of overlap in events.
When a mod says "I've removed this post for x reason" I can always still see it on the subreddit, and oftentimes front page. Why?
It is proof that the comment has remained on the site and on Reddit's servers. It is largely a deterrent, for example if someone makes death threats online, they can be reported to the local law enforcement agencies in their state country. If you were to use Google Chrome's Incognito Mode and try to re-view that same p...
Why do so many of the UK's former colonies use dollars rather than pounds as the name of their currency?
At first, this started in the North American colonies, where the currency of choice was the original "piece of eight": a Spanish coin worth eight reales, that being the Spanish unit of currency at the time. It was made that way to correspond to the German thaler, which is where the word "dollar" comes from, and so it w...
Why were gladiators socially acceptable during Roman times?
You probably need to rid yourself of movie depictions of gladiators. First off, gladiator fights were *rarely* to the death. You simply couldn't support a business model where you lost half your players each contest. Gladiators were valuable commodities. Gladiators were not always slaves, sometimes there were freemen w...
How did the ice cube in my ice tray freeze upwards?
Ice-spikes are a pretty cool thing to see! I recommend [Veritasium's video], as he explains it much better than I can.
The difference between permutation and combination and how to differentiate the two.
permutations consider the order of the elements in a set, combinations don't. If I want to consider all of the different ways I can pick numbers from the set of 1, 2, and 3, a permutation considers {1, 2} to be different than {2, 1} while a combination doesn't care.
Solution to popular Truth/Liar Door Guardian Riddle
The honest guard would tell you to go through his door if you asked him which door to go through, and the liar would tell you to go through his own. So, the trick is to ask a guard which door the *other* guard would say to go through. If you ask the honest guard, he will honestly tell you that the lying guard would say...
Why i can shine a colored laser on a different colored object.
A yellow banana doesn't absorb *all* the light except for yellow. It just absorbs some of the red, some of the blue, some of the green, etc. A white light has equal amounts of all colors, but the banana diminishes the intensity of the red, the blue, etc. So your eye sees the reflection, with normal-intensity yellow and...
Religious beliefs unchanged by facts
The definition of faith is belief in something without proof, so offering proof doesn't do much to change that. To get down to it though, many beliefs are tied deeply to someones self image. When you challenge them, most people feel like they are being attacked and harden up. Defense mechanism. Plus don't jump down the...
Why do modern movie trailers show so much of the movie?
I think they want to make their movie look as appealing as possible, so they show the best parts of the movie. So they show the best parts to get people to think its a really great movie. They don't care about spoilers because they just want money.
How come people die when strangled, but are only knocked unconscious when put in a sleeper hold?
Because if you do not release the sleeper hold you will kill them. Both actions restrict blood flow to the brain strangulation can occour with a sleeper hold.It's the length of time. A lot of people don't realize just how long it takes to strangle someone to death. If you strung someone up for only a few seconds, they'...
How does Google have a searchable version of the internet that isn't the same size as the internet?
In the same way a book has a index which is much smaller then the size of the book but allows you to find which page something is on, Google has a index of Internet. First of all the Google Search Database does contain a large portion of the text of the internet but is less concerned with the video, and pictures which ...
What is the most accepted theory on time-travel?
The only scientifically sound method of traveling through time is to travel forward in time at the rate of one second per second. Basically, time travel is entirely fictional except in the most degenerate sense of time happening at the rate it is happening to happen at, which I wouldn't count as "time travel"Time trave...
why many people believe that we should move our money from banks to credit unions
Banks are trying to make money off of you. Largely by charging fees. Credit Unions are non-profit and tax exempt. Their fees tend to be much more reasonable. People are also quite angry at the banks for pushing bad loans and selling them to largely cause the last few years\' economic turmoil, then get bailed out by the...
If humans a diurnal (opposite of nocturnal) then why is it so hard for me to go to sleep at night and so hard to wake up in the morning?
There are a million possible reasons for this. Modern technology has done an excellent job of messing with our natural sleep cycle: you could be inundating yourself with light, maybe your sleep hygiene is bad, and maybe you are looking at a TV/computer screen too close to bedtime. Any of these or other factors can caus...
What's the reason for censoring porn?
I imagine that you are talking about Japanese porn? Since this is the only ones that my friend told me about that are censored. In the case of that type it has to do with the culture. It is allowed to make porn there that shows certain sex acts so everything is blurred out. This is the reason why tentacle porn was made...
How do potatoes continue to grow and sprout without access to sunlight, soil, or Water?
They are full of energy already. That's why we eat them - they've got a ton of starches and other nutrients. They're basically energy storage nodules for the potato plant in the first place. So they have plenty of energy with which to grow.The potato is a store of energy and water. Its entire purpose is to provide said...
Why do some fluids like blood and egg yolk become solids at higher temperatures instead of low temperatures?
Protein denaturation. Proteins consist of long chains of what are known as amino acids, these chains often fold into various three dimensional shapes because this gives them their properties, proteins are basically the molecules that do 90% of the work in your body and pretty much the most important molecule for life. ...
What happens to the shadows of airplanes and jets when they are 12 kilometers in the air?
The light diffuses around them because they are far enough away so there appears to be no shadowTurn on the ceiling light in your room. Now take your hand it hover it right above a surface. See how dark and precise the shadow is? Now slowly raise your hand up in the air and watch the shadow. Same thing, much larger sca...
Why is 64bit implementation so slow?
The short answer: legacy code libraries. When a new version of something as big as Office comes out, they don't rewrite everything from scratch. They reuse a lot of old code that's been around for a while and is well tested and reliable. For something that's been around as long as Office, this will include a lot of stu...
How much pain can a single neuron send to my brain? Do multiple neurons need to be "activated" in order to feel something?
In general, yes - a multitude of things must occur before you can feel something. There are an innumerable amount of neurons in your brain, so you can only imagine how many environmental, conscious, and unconscious things can trigger any one of those neurons to fire at anytime. If we were able to respond to every singl...
Why can't they come up with a alternative to the tin can that would be microwaveable? Would food not stay good as long, or is it just not cost effective?
