There is a general myth of fast vs. slow metabolisms. Generally speaking the difference between a fast and slow metabolism might be [200-300 calories]( URL_1 ). Edit: [Actual study] ( URL_0 ) |
Your body adjusts how much water to retain based on how much water you're intaking. It wants to retain enough water to keep you hydrated during periods where you don't have access to water. By drinking a lot of fluids regularly, your body decreases how much fluid it wants to retain, because it knows water is plentiful.... |
Because people expect them to be pink. Faber was a company that made pencils, and erasers. They used Italian pumice in rubber to make erasers. The pumice supplier ran into a vein of pink pumice, and the Faber people loved the look of it. They named their product the Pink Pearl. When the pumice isn't pink, they add dye ... |
Eye color is a result of pigmentation, and varying types of scattering (similar to what makes the sky appear blue). Eye pigmentation is largely the same as skin pigmentation, going from light brown to black. So if you have brown eyes, that just means you have a lot of pigmentation in your iris. Other eye colors are the... |
Because there are another two possibilities. Say you have two numbers, X and Y. There are 4 possible odd/even combinations: * X is even, Y is even. Result is even. * X is odd, Y is odd. Result is even. * X is odd, Y is even. Result is odd. * X is even, Y is odd. Result is odd. 2/4 have an even result, 2/4 have an odd r... |
Living things tend to be symmetrical if there's no reason to be asymmetrical. For example, most animals have top-bottom asymmetry (due to gravity) and front-back asymmetry (due to how creatures move), but have left-right symmetry. Plants, on the other hand, have top-bottom asymmetry, but since they're (literally) roote... |
I'm fairly certain that most people do not experience them at all. If you get them more than very rarely you should probably be consulting a physician. There are many possible causes of vertigo, even in short bursts. Most of those causes are not good things. I get small bouts of dizzyness uf i go from sitting cross leg... |
When an object is in a close proximity to the body it orbits, over time the gravitational pull will slow the spin of the moon or planet. It sometimes but not always ends with the moon or planet becoming tidally locked to the parent body. In the case of Venus, it's rate of rotation is so slow it only spins at about 4MPH... |
The molecules in the air scatter the blue and purple wavelengths of light, creating a diffuse "blueish" hue during the day time. At night when there is no sunlight to scatter, the air is clear. When sunlight hits our atmosphere, many wavelengths pass through. We see blue because that is the wavelength that is getting s... |
They trick crows and other birds into thinking a farmer is out in their field so they avoid it. It's less about scaring them off more scaring them from landing in the first place. Their effectiveness can very though. Crows are actually pretty intelligent birds. They can recognize individual humans, and recognize things... |
Dreams lack the physical feedback you would get in the real world. Activities that involve a lot of physical interaction, like running or punching, often feel unrealistic, because while your brain is sending the command, the tactile feedback is missing. |
Actually I do this daily. You need this when you are making a measured injection of some sort of medicine like insulin. Its not so much the air in the veins which could possibly be trouble, but instead to make sure the bubbles isnt messing up your measurement. I have a dog who needs exactly 4 ml of insulin a shot. Bubb... |
Goosebumps serve the purpose of making our hair stand on end. Each hair is controlled by a little muscle and when this contracts to make the hair stand up, a little bump forms. It is mostly thought to be a remnant of evolution and not needed anymore. Our ancestors had far more body hair and making hair stand on end wou... |
Cold air can hold less water vapor in it than hot air. A cars heater will take cold air with little moisture, and make it hot air with little moisture. When people are in the car, the hot air will make moisture on the skin evaporate and the hot air will become humid. When this hot air hits a cold pane of glass, the air... |
I guess it's because we need "resolution". For instance in music, you can't leave something tensed : after tension, you need a resolution. Same with your body : when you have something that hurts a bit when you touch it and you KNOW you could juts pop it, drain the pus and it would be fine, you do it because it release... |
OK I had to make some research ([here]( URL_1 ) and [here]( URL_0 )) and this is a possible solution: (note that this is a simple solution and requires trust between Alice and Bob): Alice and Bob both have an amount of money that is a whole number between 0 to 10 (including). They put 11 boxes into a room and mark each... |
Electrical impulses already run throughout your body through ur nerves . When one of these nerves is severed paralysis occurs ! There are breakthroughs in the states at the moment, where severed nerves in the leg and back are being bridged with new technologies that allow feeling in the paralysed limb, or allowing use ... |
Spacing out is basically meditation. You are allowing your conscious mind to rest. It also acts as a reset, since your mind may be stuck in a loop of thoughts. Like, maybe you're anxious/stressed that you have an exam. You want to study, but your place is dirty. You want to clean, but can't because you need to be study... |
For the same reason our arms, heart, bones, and immune systems weaken as we age. Every time your body makes new cells, it essentially copies the older cells. But the copies aren't perfect. They might be close, but they're not perfect. And the copies of those cells are even further away from what the originals were. And... |
You have grown accustom to the acoustic level around you. Same premise for light exposure. Dark rooms seem much darker when you come from a brighter area. Once you get used to the dark and your eyes are used to it, it seems a lot less dark. |
I've always assumed it has something with relative size. To us, ants seem to move fast and we move at normal speed. However to an elephant, I would bet that it thinks we are moving fast, too. It is much easier to move a small thing than a large thing. The bug with its smaller muscles can get them moving faster than we ... |
While many drugs have symptoms that appear rapidly weed has a longer span of time needed to produce effects. Some people can smoke weed for their entire life and have no issue similar to some people being able to handle other drugs. Only recently have scientists found results that weed (THC) has ill effects. The main r... |
Overall, usually not. The hard wiring for the superior motor control your dominant hand enjoys isn't free. It takes up real estate in the brain, real estate that otherwise could be used to make you smart or improve visual processing. There are very few tasks crucial to survival that require that level of dexterity in b... |
First, let's look at the planets in our own solar system. We started discovering and naming them thousands of years ago. The closest few, like Mars or Mercury, can be seen with the naked eye, and stand out to us because they move relative to the stars. Then we invented telescopes, partially so early astronomers could l... |
If you are equating the earth to an 80 year old man: The earth is 4.54 billion years old (give or take 50 million years, assuming you're not sourcing your data from [the state of Kansas]( URL_0 )). The definition of modern humans may be sketchy. It's sometimes referred to as Anatomically Modern Humans, which are about ... |
The color of sweat and urine is largely from a waste product called Urobilin. It has a strong yellowish-brown color. This compound is a product of the breakdown of hemoglobin and other related proteins, by the spleen and liver. This enters the blood and then is filtered out through the kidneys, and to a lesser extent t... |
Overvalued- It's easier to buy imported stuff cos they're cheaper than your domestic stuff. Even though your currency is worth more, theirs is worth the same, so their prices will decrease from your perspective. On the downside, your domestic market suffers, and so do your country's exports, because they are costly rel... |
The molecules that make up dyes tend to be pretty fragile, and slowly break down when exposed to sunlight, especially with no atmosphere to filter it down. The molecules that make up a flag itself are made of sterner stuff, and stand up to the sun and the vacuum of space. > would eventually cause the flag to become wea... |
[Here]( URL_0 ) is my answer to a similar question, if it helps you. * transistors/vacuum tubes/relays - electronic switches that can be opened or closed electronically, and used to control other switches * logic circuits - a handful of transistors can build a logic circuit, usually with two inputs on one output...an A... |
Cells are more excited and move more when heated, when cooled they slow down. Sort of like when you microwave popcorn, if it's heated it'll pop and jump all around full of energy :) When there is an absence of heat (aka, cold) it is restful and unmoving. Your brain can rest easier when it isn't popping :) The body natu... |
Under the arctic ice? No. The arctic is over the ocean. Antarctica however is over a continent. Well, there can be adjoining land that is covered by ice and snow, but the arctic ice pack itself rests primarily on top of the arctic ocean. |
Calorie rounding is allowed with these rules: servings with less than 5 can say 0. servings with less than 50 calories can round to the nearest 5 calorie increment servings over 50 calories can round to the nearest 10 calorie increment. So that 250 could have as much as 255 calories in it for a US food label. You may w... |
Artists make everything you see on your screen. Animators make all the things you see on your screen move the way you see them move on your screen. Programmers write code that tells your computer when to play what animation when you press a specific button. Artists provide the 3d renders and models that respond to the ... |
Your VR1 receptors (the neuron in your mouth that deceased temperature) binds to capsaicin molecules, which give the sensation of being "hot" As you eat, your mouth salivates, breaking down that capsaicin. When you stop eating, you stop salivating, and the capsaicin that remains in your mouth settles down and bonds wit... |
Some jobs are valuable to employers because they can make a profit by charging more for a product than their costs. However, there are other jobs, like kindergarten teacher, where it's very difficult for employers to turn a profit. As a result, it's very difficult for an employer to financially motivate someone to be a... |
Ice is cheap, and fish are fine with the concept of getting their outsides wet. You can't sell steaks on ice, because the outside of a steak is the insides of a cow and it's not supposed to get soaked in water. Fish live in water, so they are pre-made with water-friendly outsides. Refrigerators need doors, or lots of c... |
There are small sacs in your lungs that bring the incoming air in close contact with your circulatory system. This quickly brings the air close to body temperature , as well as enabling the transfer of oxygen and carbon dioxide. Lots and lots of surface area. You're not warming up a .5 L balloon of air each breath, you... |
Sex activates hormones that masturbation does not. Having sex more often actually increases libido for that reason. |
> Import tax be passed on to consumers by raising the price of imported goods? For any goods that are imported, yes (which is a lot of them, at least in part). The idea is this incentivizes people to buy domestic goods, which will create more jobs domestically. It also tends to hurt exporting businesses, because other ... |
Most things get smaller when they get colder- it's a principle called "thermal contraction." Most things get bigger when they get hotter- "thermal expansion." Solids are denser than liquids. Water is weird in that it doesn't work this way. When water becomes ice, it actually because slightly larger because of its molec... |
For the same reason seeds can sprout through concrete I imagine. Plants seek light, they'll grow around whatever they need to to get to it easier. |
Both of those things—poor appetite and extra sleeping—are also signs of depression. It's something to at least be aware of. I know that for myself, when I find myself in that position it is usually a sign that I am drifting down into a depression. What's more, not eating well and not sleeping "right" both tend to aggra... |
For the same reason we might mindlessly pick at some dried glue on our hand--our subconscious mind sees it as something foreign that doesn't belong on our body. Of course, scabs are part of us (at least temporarily), and they're critical for wound healing, which is why the picking stops when our conscious mind kicks in... |
Hair and feathers don't transfer heat well, an example is if you're outside on a hot day and you feel your hair it's very hot but your scalp isn't. There are... multiple ways to approach this question, so I'm going to throw a bit of spaghetti at the wall and see what sticks. * The heat doesn't totally transfer from the... |
When you shave against the grain the razor tugs at the hair in addition to slicing through it, pulling it a bit farther out of the follicle. This makes it much easier to get ingrown hairs and irritation on the skin. Edit to elaborate on everyone else's experiences by adding my own: Using Mach 3s and all that newer stuf... |
Yep, it is a specific marketing strategy aimed at regular tv watchers. They start running a long commercial (1 minute) that hopefully does a really good job of being remember by the audience. This if often not hard because 1 minute commercials often stand out because they are so long already. They will run these for a ... |
Sports fans, especially baseball fans, emphasize and collect player statistics. One such statistic is how many often a player hits the ball when they're up to bat, and it is calculated as (number of hits)/(number of times the player has been up at bat). Because of this, it is a number that varies between 1 (perfect, al... |
/u/Gonzotronic has it right. It comes down to energy and efficiency. Using our muscles takes energy and work. If we're in a position where muscles aren't working, less energy is being used. Slouching is the best example. You're essentially just relaxing the muscles of your spine and trunk until most of the weight/press... |
This legitimately was always my problem with trying to get into books. I would be reading the words but thinking about something completely different haha. Good question. I'd like to hear an explanation as well. |
It depends on the species. Horses fur gets fluffy in the winter because its body responds to the decrease in daylight hours (which is why show horses are kept in barns with lights on year round). But dog bodies respond to temperature to shed and fluff up. So all in all it depends! Hope that helps :) |
Day to day things are stored in short term memory. The mundane gets replace a lot. Long term memory is stored elsewhere in the brain. Looking at an old photograph will bring those memories to the short term part of the brain where then the shock process occurs. Other forms of this happen when you get older, move a lot,... |
Honestly I dont think this is an actual thing that has an explanation. Its more of a preference. I dont think humans have an innate love with viscus liquids like we do with.... idk cant think of a good example, but its not programmed in like our love for pheromones or something. |
The heat helps to get the mucous flowing and you can clear out your pipes, giving you a temporary relief. If you've got a stomach ailment it's mostly liquid so it's easier on the stomach too, but you're still getting nutrients and food so you feel better after starving for awhile. It's a good food overall, but has adde... |
Because the blood vessels in your feet are used to having the gravitational pressure of blood pooling down there. The vessel walls are thicker as a result, so they don't apply pressure to the nerves in your feet. Alternatively, your head is filled with much more delicate blood vessels, not only because it's not conditi... |
Yes, you would use [Newton's law of cooling]( URL_0 ), set it equal to the temperature you want, then solve for the value of t. The constant *k* is something you would either need to look up, or solve for yourself by taking two temperature readings at two different times. |
There might also be something around the quality of actors being used. Recently, we have seen top quality actors shift from movies to television. More A list actors are getting into television. These actors are also still making the occasional movie. So they have large time commitments outside of the tv show. I would g... |
At the very basic level, I think what you're asking about is "machine code". Let's imagine a basic computer. It might have a few different instructions: - INPUT - read a number from the user, and store it in a "register" - OUTPUT - take the number in the register and show it to the user - GET - get a number from memory... |
There's no real reason not to, to be honest. Plastic bottles, specifically polycarbonate bottles, which have been the subject of much scare-mongering for years are fine to refill. The big worry about "chemical leaching" isn't a worry unless you're the sort of person to keep reusing the same polycarbonate bottle for yea... |
Nicotine is an addictive chemical that is in cigarette smoke. There's other stuff in there too. People that don't like smoking, don't like the taste or feeling of smoking but, if you gave them nicotine skin patches or pills for long enough, they'd become physically addicted to the chemical, just like a smoker is. |
It depends on the animal but, if you look at raccoons which have thoroughly invaded Japan and Europe, and how incredibly successful they've at been colonising North America, when originally they only lived around the southern states, they're a pretty good example They have easy access to a huge amount of food, by explo... |
Fuel is generally a string of carbon atoms with two hydrogen atoms attached to each one. To make it into CO2 and heat you have to mix it with oxygen. So CH2 + 3O - > CO2 + H2O. Carbon weighs 12 units, hydrogen weighs about 1 unit and oxygen weighs 16 units. So from the above formula we can see that 14 units of fuel and... |
Same reasons animals have claws, in many respects. They help us grip things, peel things, scratch, scrape... To this day, humans sport broader fingertips than other primates. Whether fingernails are an adaptation that helps to support broad fingertips or a side effect from the loss of claws is unclear, Hawks said. Anot... |
So, super simple explanation is "Proteins!" Essentially, bacteria have a certain type of protein surrounding them (generally speaking there are two types of bacteria which are differentiated by their outermost membrane). Your cells are made to be able to identify these proteins with receptors on the outside of them. Th... |
In of itself going to the bathroom is a boring activity. Ya just sit there waiting for whatever to pass through you. It's a quiet solitary activity. And it's great. For a lot of people it's the only times of day where they can be alone and take a breather. Where they can read, look at a video etc. there's also the fact... |
Quite simply, they arent. these sort of threats dont happen often enough for the postal service to have a devoted structure in place for it. Now important positions and companies may have internal processes for it but there is no formal system used by the public mail. |
That's more or less how a flashlight and searchlight work(think of the batsymbol). You have a parabolic dish and a sender in the centre that emits EM which bounces off of the disk and "doubles up" on the transmitted signal. We do use visible light for communications all the time. One big example is fiber optic lines, i... |
Going outside firstly removes the trigger and stimulus that's causing the stress - and so they can get out of an emotionally charged situation. Fresh air may also be a change in temperature, so they have a different physical response too, and that may help them breathe deeper, giving the stress hormones a chance to dis... |
Slit pupils are not a purely reptilian thing. There are reptiles without slit pupils, and mammals with slit pupils, for instance. They could have some advantages. For instance, circular pupils are often a quickly discerned threat feature by many animals. To the point that natural camouflage evolution in many species ev... |
The Single Market is essentially an agreement that we harmonise our laws and regulations so that everything is legal in all EU countries. Without this, you can have conflicting laws in different countries, meaning some products are illegal in the other country. For example, in the USA all eggs **must** be washed. In th... |
You're talking about blood vessels, and you tend to see them "creep" when your eyes are irritated due to some external factor or when you're lacking sleep. From reading the other comments it's clear you are talking about veins. Your eyes use muscles, pulling your iris open and closed to let more light out or less light... |
No there is not a "real" as in physical dollar for everyone you bank online. However that has little to do with the internet and stated long before we had online banking. Money existed in theory only and without any physical coins or banknotes to back it up for long before computer banking came along. This is how banks... |
The CIA is known to be ridiculously overt in their actions; back in the day, Allen Dulles would arrive into the targeted region with about as much pomp as one would expect for the President himself. The CIA method of regime change relies not on subterfuge but on throwing money at whatever political group can do the gru... |
Your eyes are filled with a somewhat thick fluid. When you rub your eyes, this causes the fluid to apply pressure onto the retina. This pressure tricks the light sensing cells into thinking they are receiving light, so the cells send signals to the brain. Your brain interprets this as light and you see spots / rings or... |
Its called a digraph. Qu makes the /kw/ sound in the English language. You can thank Latin origins and the Greeks for that. There are a lot of words that have Q without a U after it, but they are mostly in Semitic languages. Qatar, burqa, qabab. According to Wikipedia, C, K and Q were all used in early Latin to represe... |
Back in the day, PCs didn't have hard drives. They only had [floppy disk]( URL_0 ) drives. A common configuration was to have two drives, usually one 3.5" drive and one 5.25" drive, so they were designated A: and B:. So when hard drives became common, they were given the next letter - C:. A lot of programs relied on ha... |
Here's an excellent article on exactly how it's accounted for: URL_0 Basically the payment for the card is entered as a debit under cash, and then an credit entry for the gift card liability is entered. When you use the gift card, you have a debit against the gift card liability and a credit applied to revenue. the lin... |
Actually it's not logarithmic, it's closer to a 1/x relation since what you turn is not a resistor, but a variable capacitor. A capacitor and an inductor are used in the tunning circuit attached to the antenna. But log scales are indeed used in frequency plots since it better represents the behavior of systems. Behind ... |
Quilted paper towels have more surface area than non-quilted. Our intestines work the same way, to absorb more nutrients. |
Four-legged animals use their whole spine (and the muscles along it) as a giant flexible spring. So they have a whole new huge source of power, and a much longer gait than what just their leg length provides. It gets down to the slow and fast twitch muscle fibres in our body. Humans have evolved with higher amounts of ... |
The nerve endings on your meat whistle are more sensitive that the rest of your skin, you have over 20,000 nerve endings alone on the tip! The thermoceptors of the skin are not only stimulated by temperature but also some chemicals. Menthol cools, capsaicin warms, etc. These receptors (TRPV1 or -2) are activated by the... |
The crash came from an excess of bad debt. Folks had been writing loans to people that can't pay, and eventually ran out of capital to keep writing loans when too many folks didn't make their payments. It was really a team effort. Banks shouldn't have been writing multiple mortgages to folks that work part time at McDo... |
What you burp is actually carbonic acid (H2CO3), which is a mild acid. The CO2 that is dissolved in the soda can form some H2CO3, which if burped will enter the nose cavity. The airways are not as well suited to hold acidic solvants, and will therefore sting a little. |
[This page]( URL_0 ) has an explanation. The point is that it's not the molecular weight that determines an element's melting point but rather what kinds of forces exist between molecules. Think of it like the molecules are college students at a party. Each lithium atom is like a skinny sorority girl, but each one is p... |
Friction reduction is due to aqua planning. Basically, you get a layer of liquid in between two surfaces, and a liquid causes a lot less friction than hard on hard material. As for dampness, I'd assume you mean barely wet surfaces. If a surface was perfectly smooth, it would become less frictious from any amount of liq... |
So lets say you own a company that sells clothes. You get all the proper paperwork saying that your company is authorized to operate in your home country. So you are free to sell it's clothes within your own country. While there might be some minor regulation differences between regions, normally countries take steps t... |
Tags are located inside clothing so they don't spoil the look of the garment, and they are usually placed on a seam as the printed strip of fabric needs to be sewn in. Places like the back of the neck are going to reliably always have a seam and area easily accessible so they are standard locations for tags. not enough... |
Yay, I can answer this! I was a court reporter for three years after doing two years at a college to get a certificate for captioning and court reporting. The machine that court reporters/stenographers use is called a stenotype. The keyboard of a stenotype is blank, but [this is what all the keys represent on it]( URL_... |
Let's compare video editing to building a car. So you're editing your video, but really it's a collection of parts. Multiple footage clips, effects like color correction, etc. The computer is able to tell you that "yes, these parts put together make a car" but rendering is where the parts actually get put together and ... |
Drive car into woods, file a stolen vehicle report, collect insurance money. same reason they wind up in water bodies as well. Insurance fraud I'd like to address the "30 years ago cars were simple to fix" part: 30 years ago, your average automobile had an engine that would need rebuilding a lot sooner than the cars we... |
Because when you are erect there is a muscle that closes off the tube to your bladder precisely because we don't want pee in our spunk. When your little buddy finally relaxes, so too does the muscle. |
Glasses are usually made with Polycarbonate lenses while phone screens are made of thin, pre-stressed glass. Polycarbonate will dent and scratch easier than glass because its softer than glass, but as a result it will not shatter. ~~Usually you dont notice these, and if your glasses get really bad, you can actually get... |
It differs from country to country. I assume you are talking about Trump in the US. The only, ONLY, way a sitting president gets removed is if he's convicted of a criminal offence. However, the president is not beholden to the normal justice system, since technically he runs it. So the only, ONLY, way this happens is i... |
It's extremely far from Earth and even further from the sun, meaning a minuscule amount of light actually hits it. If no light hits the planet, then you're looking for a dark spot on a dark background (space) and it's extremely difficult to see. Its existence is postulated based on other observed facts, but for the rea... |
Some actions inherently end in a sudden result -- like if you snap a pencil, the final break happens very suddenly, no matter how slowly you bent it up to that point. Sudden things release a lot of energy (such as noise) all at once. |
The diaphragm muscle allows the lungs to expand and collapse. If you get hit hard enough in the diaphragm it begins to spasm and can't inflate the lungs. |
No, the bone doesn't break off. The flesh clings on, and rots, leading to a possibly fatal infection called gangrene. To prevent this, the flesh must be cut off. The protruding bone is typically then removed with a saw, so that the skin can be sutured shut. Your cells are mostly water. When water freezes, it expands, e... |
They had issues in the 20th century but were they worse in the 19th century and earlier? Leaders such as Stalin who ruled with an iron fist. In other words they wanted to be in control fully. They wanted a society where no one questions the leaders orders. Like when they stripped farmers & peasants of their land becaus... |
Baking powder, these days, *isn't* just baking soda and cream of tartar. Now, you usually get double-acting powder, which has two pairs of chemicals that, when they get wet (or wet and hot, for one of the pairs), react and give off carbon dioxide. That way, even if your, say, pancake batter has been sitting in the frid... |
Let's pretend there's only three currencies: The American dollar, British pound, and the euro in the European Union. At different times, each one can be stronger or weaker than another. This month, the dollar is strong, the pound is weak, and the euro is weaker. While I'm an American, I like British suits, so I shop on... |
When somebody strikes your chest, specifically the solar plexus, this makes your diaphragm contract and spasm, making you lose control over your breathing. When you breath in and out there is a portion of air that isn't used for respiration and it is called dead space. There is always supposed to be a certain volume of... |
