why did so many Slavic countries abolish their monarchies immediately following World War 2? | They didn't "decide" a damn thing. Each of those countries was occupied by the Soviets after the war, who supported the rise of communist governments. Those governments, in accordance with communist ideology, abolished the existing monarchies. Also, "Slavic" does not mean "Eastern European". Hungary, Romania, and Alban... |
The British Political Parties. | _URL_0_ sums it all up pretty well. Some personal opinion from an Englishman who is not at all politically savvy:Conservatives or Tories are essentially the upper class running the country, ruining it for everyone except the mega rich.Labour party are essentially the working class ruining the country for everyone excep... |
If Earth is only 4.5 billion years old, how was NASA able to view a star with the Hubble Telescope over 5 billion light years away? | If your car is only two years old, how can you use it to drive to a house that was built ten years ago? Something being 5 billion light years away simply means that the light from that object has been traveling for 5 billion light years before we see it. The age of the Earth is not relevant in that calculationBecause t... |
What's the difference between a headache and a migraine? | Migraines are hereditary and often last for a few days with different stages. They can be triggered by chemicals in foods like cheese or alcohol, by bright lights or flashes, loud noises, strong odors, hormones, stress or heavy thought, or even just cold temperatures. They aren't unbearable at first, but get steadily m... |
Why do babies have to have their burps/other gas manually expelled and does it work on adults? | Babies are super useless at doing anything themselves, so you have to help. Having trapped gas sucks for everyone, but I bet it sucks more for a tiny person who has no idea that gas even is a thing, and can't move around to force it out. If they need to release that gas and can't on their own, they scream and hurt and ... |
Can someone please explain to me(like im five) what it is with an EMP that disables electronic devices? | Do you understand how radio works? Electricity moving in a wire in the transmitter creates a wave in the electromagnetic field that surrounds us. This wave moves electricity in the receiver, creating a signal that the receiving radio uses. Well an EMP is just a really short, extremely strong radio pulse. It creates lot... |
What is the debate around the Free Basics app Facebook made in India and Egypt? | It's against net neutrality, it's sort of like the television plans, it's free access to Facebook and certain other websites Facebook approves, you will have to pay to access for other sites .People would rather have the poor have access to no internet than to have access to a curated selection of the internet focused ... |
What are dogs sniffing for before they go poop? | Dogs are territorial creatures. If they have to do their biz~, they can accomplish two things with one act. They smell for traces of another dogs poop or piss to locate it. By going on top of that, they are representing dominance over the other as they have marked their territory over another's mark. |
Why aren't there any cross-country taxi services? | Buses. Buses are as close as you'll get. It's because the cost in fuel alone would rival that of a plane ticket, but then there is the added cost of maintenance, the fact that you would need to stop for hours a day in order to keep driving straight because the cabbie would need to sleep. Not to mention the fact that fe... |
severe allergic reactions to solids in the air | People with food allergies are allergic to specific things in the food, called allergens. These are usually protiens, which are very small particles. They are so small and light that they can be lifted up into the air and carried by a breeze. Think of how dust can be carried by a breeze. This process is called aerosoli... |
How do TV channels/shows know how many views they are getting? | The Nielsen Company. I believe they have around 10,000 US households and they give them a special device that logs when each user is currently watching tv. This is also how demographics are gathered. |
Why do rappers often have another guy up on stage during live performances who raps the end of some of their lines with them? | Hype man. Performing on stage believe or not is physically demanding especially if you're on tour all the time. That's why a lot of them pass out. So when the rapper is up there he has to balance out his energy so the crowd can still feel the vibe. The hype man will get the crowd hyped up so the rapper can focus on rap... |
How do buffet restaurants make profit? | They make food cheaply and charge more than what most people eat. Most people will have 2-3 servings. They generally charge enough to pay for 5-6, thus the few that eat more than 6 are more than compensated for.Mass produces food, doesn't have to pay more staff for presentation of said food, serving said food, and most... |
Why do all living creatures have to die, why can't we live for ever? Also why does there have to be a deterioration of the living being at some point in their life? | We don't have to. Google's Calico division is working on curing death, as well as Aubrey Degrey's SENS organization. No guarantees, but it's looking like it'll be between 20-50 years before we have something concrete. |
What makes some melodies "catchy" and others not? | Basically it depends on how easily one can sing the song. Composers will choose easy intervals and simple rhythms to make it as easy as possible for the audience to remember what was played or sung. This goes back to Mozart and even farther. You would most likely remember a Mozart tune better than you would a Wagner tu... |
How do we know the half life of Uranium 238 is 4.5 billion years if we haven't been around long enough to test it? | Basically the same way a paramedic/nurse can work out your pulse in beats per minute without counting your heartbeat for a whole minute. Half life is an example of exponential decay, and so it follows a very regular, predictable mathematical pattern. If we have data about how it has decayed over time now, then we can e... |
You are thirsty. Your body needs water. How long does it take for the water you drink to "rehydrate" you? | I'm not sure, but I figure if I put a slightly accurate answer in here, someone else will explain why I'm wrong in great detail and you'll get your answer that way. You're welcome in advance. I always notice that if I'm really thirsty, I'll feel a bit tired as well. If I drink water, I feel more awake in about 15 minut... |
How do we, as humans, perceive time? | Your body has a reminder system, or a bio clock which tells us that we did something before, at almost the same time of the day. This works only if we had done it repeatedly, for example sleeping or waking up. If we donot have access to daylight, this clock can go horribly wrong after long isolation. |
Why does blocking out someones eyes in a photo/video make them unrecognizable? | It depends. If you cover just the eyes, it will not disguise anyone. The person will still be identificable. Maybe it will be a little more difficult, but that's it. If you cover a larger area, you are covering the area where humans take most of their cues for recognizing someone. You could still be showing enough info... |
possible ramifications for Canada if Mitt Romney were to be elected president | Hard to be sure the main concern for us is that one of them turns around the economy so they keep buying our crap. Both want increased relations, both want to open markets to us, both think we are a strong ally. I think Romney is marginally more likely to start a war, and as we are a part of nato that would have an imp... |
Are radio waves three dimensional? How would they look if simulated/visualized? | There are two things to consider: **Propagation** This one is simple - it's where the radio wave goes to. The image you 've linked to is a representation of 2-dimensional propagation. In 3 dimensions, radio waves simply propagate in a sphere, rather than a circle. **Polarization** If we imagine radio waves to be a seri... |
How do projectors project the color black? Isn't black just the absence of light? | They don't. It's your stupid human brain tricking you into seeing black. In fact, the lack of a real black is one of the problems with projectors. |
How is it that i'm left handed but do some activities like a right handed person would? | As I understand it, left/right-handedness isn't a 100% binary thing. You can be left-handed for *most* activities, but still be right-handed on a few/some others depending on how you were taught, how you grew up, etc. |
What the Beatles did to the world | Well, they were not only the definitive rock band at the time, but were highly experimental. For example: they were the first rock band to make usage of a stringed quartet in a pop song--I believe that song is Eleanor Rigby. They helped popularize eastern/world music, shedding light on traditional Indian ragas and cert... |
What kind of healthcare options do Americans living in poverty or homelessness have? | I see some on here saying "Medicaid" and ERs. This is misleading. First Medicaid only applies to certain populations of the poor while others are left without. Obamacare did not fix this as half of the states and the ones with the highest rates of uninsured do not offer Medicaid to people just because they are poor, th... |
Who profits from medical bills? | Everyone, to some extent. A big chunk goes to insurance. A large part of the higher cost of healthcare in the states is due to administration: figuring out who exactly pays for the service, and how much to pay. Single payer systems are much simpler to administer. Beyond that, doctors at least tend to be paid better as ... |
Why is the "www" in a URL replaced with something like a number in the end like "ww28"? | Because they want to, basically. An URL is read from right to left, and each word narrows down the area a little more. .com, .uk, .se, .me is countries. Then you have a domain, those are most often one company . This is .facebook. , .google., .youtube., and so on. Some companies also want to narrow it down a little mor... |
Why is percussion so much less prevalent in classical/orchestral music than it is in rock/pop music? | Piano, Xylophone, Gong, snare, bells, chimes, vibes, triangle, cymbals, timpani, snares, bass drum, wood block,and a lot of others are all commonly used in classical/orchestral/wind ensemble music. Some pieces even heavily feature percussion. _URL_2_ Anvil Chorus. _URL_1_ 1812 Overture _URL_0_ Vesuvius And many many mo... |
Why shouldn't the homeowners be present when a realtor is showing their house? | Potential buyers should be able to give honest critism about the home they are looking at to their realtor so that the realtor knows exactly what they are looking for to fit them into the best home possible. Its awkward to mention things you don't like about a house in front of the person who hopes you are going to giv... |
How exactly does an actress posing nude or appearing nude in a film help their career? | It helps by: * getting them attention* expanding the sorts of roles they are considered for* for child actresses, it prevents them from being typecast in teeny bopper roles It hurts by: * getting a reputation for their bodies, not their acting, which can make it hard form them to get roles when older alternately, it ca... |
Why, when you play two keys next to each other on a piano it sounds so ugly? | It's all about the frequencies of the notes. When you play two notes that are an octave apart, the frequency of the higher note is double the frequency of the lower note. Think of walking with a little kid, where they take two steps for every one you take. The rhythm of your steps sounds good. When you plan an interval... |
How would a Crimean declaration of independence or union with Russia differ from Kosovo declaring itself independent from Serbia in 2008? | Kosovo's self-proclaimed independence has been recognised by 108 UN countries, and one non-UN country, the Republic of China . The remaining Serbs from North Kosovo want to remain in the Republic of Serbia, but Serbian majority towns are now rare in the Albanian-dominated, partially recognised Republic of Kosovo. It bo... |
How can people overpay their taxes? | Your employer takes money out of your paycheck throughout the year to pay your local, state, and federal taxes. The amount they take out, however, is just an estimate how much tax you will probably owe at the end of the year. There's no way for the state, local, and federal governments to know what you actually do with... |
What exactly is the internet and who runs it? | The internet is a bunch of computers owned by different people connected by cables owned by different people. That's it! |
What exactly does the word 'kike' explicitly mean and, as a Jew, why should I be offended? | "Kike" is short for the Yiddish word for circle. Illiterate Jewish immigrants used to sign with a circle instead of an X. Like most of the words bigots like to use for others, few actually know the meaning, they just use them to be hurtful.I read, from Wikipedia admittedly, that 'Kike' is short for the word 'kikel' whi... |
How do fridges work? | Before I talk about the action of a refrigerator you need to understand that when you compress gas it gets hotter. The reason for this is that some of the work you put into compressing the air is converted into potential energy in the now compressed gas. You can test this with a bicycle pump. If you fill up a tire the ... |
Why do they close off entire avenues for the Pope's visit? | Safety reasons. Typically where he goes, a crowd will follow. They wouldn't want to reopen the streets too soon with pedestrians and bystanders still randomly wandering about. You have to give them time to disperse. Also, they lock it down somewhat so that they cannot attack/harm the pope. I've seen recently they were ... |
Music: Why do we associate major keys with happiness and minor keys with sadness? | It's a conditioned response. More specifically, a grossly over-simplified conditioned response. Around the Ars Nova/Renaissance periods of music history, musical modes were considered to represent emotions. In fact, each musical mode was intended to be used to suit a particular mood. All of the modes differ by certain ... |
how are nutritional values measured? How do companies obtain the nutritional values that are printed on the packaging? | My English isn't perfect, sorry in advance. For kJ or kcal, they use a bomb calorimeter. Basically a chamber where they burn the food and can measure exactly how much heat this generates. They have done this for almost every food source. Add in the fact that not every food source is 100% digestible So now there are cha... |
Why does our hair turn grey as we get older? | Hair gets it's color from a pigment produced in the hair follicle. When the cells that produce that pigment stop working, hair grows as grey. The older you get, the more likely those cells are to stop working. |
Why can a cell tower give me a signal hundreds of yards away, but my WiFi antenna won't go through my bathroom wall? | Different frequencies have different propagation properties. Some signals are absorbed by wood and plaster board while others will pass right through them. Radio waves are light, and just as you can absorb, reflect, diffuse, and scatter light, so too radio waves. With enough energy you can "shine" your wifi bright enou... |
How is "overclocking" possible when the components were only built with so much physically possible capability? | Parts are sold with artificial limits installed. This is done to protect the part from damaging itself, usually due to overheating. When you over clock a piece of hardware, you are turning off that limitation in order to get better performance out of the hardware. You void your warranty and risk damaging the part if do... |
Why are gasoline powered appliances, such as pressure washers or chainsaws, more powerful than electric? | Electric motors aren't inherently weaker than gasoline motors, it's just that there's a limit to how much electricity you can draw from a single wall outlet, or how much you can carry in a battery. Gasoline motors don't have this problem, because A) gasoline contains a lot more energy for a given mass than batteries, a... |
How does frostbite destroy and permanently damage flesh? And how do you know if you get it? | I'm no medical expert, but my understanding is as follows: Frostbite is caused when tissue freezes after prolonged exposure. As your body cools, blood is drawn away from extremities such as fingers or toes and concentrated in the core to protect vital organs. This drawing away, coupled with a constriction in the blood ... |
Why couldn't I see my dog directly? | Your peripheral vision is more sensitive to low light than your central vision. When looking at distant astronomical objects, for example, it's easier to see them if you look just a little away. |
How do flooring companies make a floor surface that is LESS slippery when it gets food/liquid on it? | Most of the time there's grooves to give way to more traction. Think of concrete in playgrounds, most of the time it has grooves in them to keep the kids from slipping if it gets wet. It adds extra traction |
as an European, why do areas with frequent natural disasters as hurricanes have so fragile constructions instead of using strong materials? | Cost and the low likelyhood of a repeat occurance in that specific area. also most people don't want to live in a bunker, they want to see the sea |
What is happening to a dog's body physiologically when an owner leaves them in the car on a hot day? | Dogs being left in cars with the windows cracked can definitely reduce these effects, but is still not good whatsoever. Especially when the windows are shut, being left in a car is incredibly dangerous for a dog. At first, the dog will begin panting and their blood vessels will dilate in an attempt to cool themselves d... |
Why did the Arab countries only developed normally until the 70's? | If I remember my history correctly : Up until the 1970s, the world pretty much left the Middle East alone. Then the US and the USSR got in the ultimate pissing contest: the Cold War. From there, both superpowers wanted governments in the region to have heads of state that would be loyal to one or the other, especially ... |
Why is gene therapy so dangerous? If there is enough research done about what they are replacing, shouldn't it be safe every time? | It isn't as dangerous as you're making out. There are two main risks: toxicity or infection from the vectors used to insert the gene, and disruption of an existing gene by inserting the new one into the middle of it by accident . Neither are insurmountable. The main problem right now is that it just doesn't work very w... |
How do I decide to use heat vs ice on an injury? | Depends on the injury and when you are treating it. For a muscle injury , the immediate treatment is to follow REST . The ice is used to slow blood flow to the site and reduce swelling. After some time, it's time to treat the injury through rehabilitation . At this time it is common to use heat to relax the injured mus... |
Can you explain DNA like I am five? | The basics: DNA is like a set of instructions, or like a recipe book that tells the cell what proteins to make. When a cell wants to make a protein, it first makes a copy of the recipe by transcribing it into mRNA . RNA is structurally very similar to DNA, but is less stable and single-stranded instead of double-strand... |
Why is it when I swallow my own saliva I am not rehydrated unlike when I drink water? | I live near a reservoir that supplies water to my city's water system. If I fill a bucket at the sink, then take it to the reservoir and dump it in, why does the level of water in the reservoir not rise? Because the water came from the reservoir in the first place. Swallowing your own saliva can't possibly rehydrate yo... |
Why do cats have a 'no fucks given' nature, where as dogs don't. | Dogs are descended from pack animals and have social instincts, cats are descended from solitary predatorsNo answer, just a joke on the side > What is the difference between a dog and a cat? > > The dog thinks: this man here gives me food, a home and protects me. He must be god. > > The cat thinks: this man here gives ... |
What was the practical difference between shooting a bow horizontally and shooting one vertically? | The string would be much closer to the underside of your arm which would result in some delightfully painful bruising/rashes . You also get a longer draw holding it vertically, as the string pulls next to your body, so the draw length should be: the length of your arm plus shoulder span . Holding horizontally, max draw... |
Why do animals like birds and squirrels move around in twitchy motions, when other animals move around smoothly? | Birds and squirrels cannot move their eyeballs, so in order to look at something they have to turn their entire head/body, resulting in the "twitchy" motion.First of all it is for safety. Movement is eye catching. You are easier to see when you move. So animals that can move in quick bursts do so. Secondly physics and ... |
What would happen if we were to punch a hole straight through Earth? | The rock that makes up the earth acts a lot like a liquid as you get below the crust. The hole would quickly fill up with the molten rock. Honestly, if something punched a hole through the Earth, I'd be way more concerned about what did it than the hole itself. |
What is it that makes some people believe the world is flat? | There are two broad categories of flat-earthers: trolls, those who claim to believe it as a way of entertaining themselves by irritating others, and blithering idiots who will believe any old tripe that makes them feel special.Mental illness, lack of undrestanding that the world is bigger than they can observe, failing... |
Why does it sting when we get hand sanitizer on open cuts? | The hand sanitizer probably contains alcohol, which is an astringent--meaning, it constricts body tissues. The sting is due to the sudden shrinkage/nerves reacting. Witch hazel or salt water would also have the same effect. |
What kind of damage can a separated ice shelf do? | The ice sheet is already floating on the ocean so it breaking off and drifting out to sea will have little effect on global sea levels. The real worry is that the ice sheet is holding back the advance of glaciers that are *resting on land* and if their advance speeds up they will be transferring ice from the land to th... |
Why does the body raise its temperature when it lacks sleep? | The body tends to follow a set sleep schedule and when you do sleep your core temperature drops. If you stay up past your usual sleep cycle your body will still drop in temperature around the same time which is why some people feel cold late at night, but since you aren't sleeping the body heats back up so the transiti... |
Why do we say that spiderwebs are "stronger than steel"? | because strength is measured proportionally to the size of the object in question. In this case, the strength being measured is tensile strength We don't think of spider webs as strong because they are so small in scale. However, if we produced a piece of steel as thin as the silk, it would take less force to snap it t... |
Why couldn't we use dust grain dispersion instead of fuel in a combustion engine? | Internal combustion engines work by igniting fuel under a compressed piston, which rapidly heats up the air and causes a dramatic rise in pressure, pushing the piston out. The two most common engines are petrol and diesel , lower piston pressure and lower power output. Low temperatures also mean lower [max. thermodynam... |
Why does listening to music on a phone through an auxiliary connection work better when your phone sound is turned down a little bit? | As far as I have known it, the higher you set the volume on anything, the more current it tries to push through. This is because the speakers in headphones / your car stereo / your £2000 5.1 surround system all work in basically the same way. By passing current through an electromagnet, it causes the big squishy bit of... |
Why does starchy food stick so hard onto kitchenware? | Starch is used as poster glue. The gluten in wheat additionally makes the strands of starch molecules link together to make a tough solid. |
If someone is fully aware they are brainwashed, does that negate the 'brainwashing'? | It lowers the effect, but doesn't remove it completely. E.g., the price "99.99$" would look more attractive than the price "100$" even for the person who's totally aware that it's just a marketing gimmick |
Why do some businesses require a signature when paying with a card, but other businesses don't? | Merchant agreements vary. But in many cases if a customer disputes a charge, the merchant is required to produce a signature, I'd they can't it is charged back. Many companies for convenience have decided just to waive getting one for transactions under a certain dollar amount. So you dispute a $4.37 transaction at a c... |
Can there be two humans that are exactly the same? | theoretically, there's nothing preventing it. Just don't count on it happening ever for the rest of time.The answer is yes, but because of the amount of people that can be possibly "made", the chances of actually having two exactly identical people created independent of each other is extremely low, statistically speak... |
Is there an interesting explanation as to why virtually all talk show hosts sit to the right of their guests? | "Because it makes them seem powerful. In Western culture, we read from left to right, and we watch theater and television that way, too. Our eyes end up on the right side of the screen—where the host sits . In the theory of stagecraft, it's understood that a rightward placement telegraphs royalty. So no matter how famo... |
How the curiosity rover is controlled | Small computer programs are sent from Earth to the rover. For example, we might send the following instructions: * Turn 90 degrees to the right.* Drive forward 5 meters.* Turn 180 degrees. Then we wait the rover gets the commands, executes them, and then sends us back information about where it thinks it is. We can the... |
why is a prescription called an Rx? | It's short for "recipe." Originally, it was a recipe for a specific compund that the patient would take as a cure. _URL_0_ > ℞ is a symbol meaning "prescription". It is sometimes transliterated as "Rx" or just "Rx". This symbol originated in medieval manuscripts as an abbreviation of the Late Latin verb recipe, the imp... |
What would an explosion look like in space? | There would not be much fire: fire needs oxygen. So a manned spaceship could burn, but only where there's oxygen like a cabin or an oxygen tank. Most importantly, there would be NO SOUND. Sounds travels on air and there is no air in space. Also, it would be super dangerous to be near an explosion in space because witho... |
What causes the difference in intelligence between persons? | A combination of nature and nurture. Genetics obviously plays a role at the beginning of life. Someone genetically inclined to have higher cognitive functioning can still be a naive moron if raised in such a way. Same with an average Joe who's seen the world and learned how to process information in an efficient way. |
Why do spicy foods clear up your sinuses? | Capsicum annum is an ingredient in peppers . It causes inflammation to reduce in the sinuses. I wasn't able to find data as to WHY Capsicum annum does this, only that it does it. |
Why does your voice get choppy when you speak into a fan? | Yes. The sound waves are interrupted by the moving blades, and some get reflected back into your ears while some are absorbed. This leads to the odd robot voiceWhat you hear is best described as tremelo, where the volume of your voice is undergoing rapid volume fluctuations. As the fan blade spins in front of your mout... |
What happens in our brains when we feel awkward? | I've always wondered if we would feel awkward if we hadn't seen more perfect examples of the behavior? I never feel awkward dancing or singing at home alone. Repeat the same performance in front of people and I feel very awkward. I'd say it has to be in our expectation but also perceived acceptance of others. If someon... |
Why are some showers very steamy, but then the next day in the same shower there will be no steam at all, even at the same temperature? | Barometric pressure, as the pressure rises and falls with different weather patterns, the steam in your shower will stay around longer or shorter. |
If a homosexual couple gets legally married in one state, and then move to another state where it's not legal, is their marriage still recognized? | As of right now, in many states no. That is why many of the lawsuits in states without same sex marriage are using the 14th amendment and violation of the full faith and credit clause. I believe by end of June after SCOTUS rules, it will be legal in all 50 states, although some southern states might try to resist. Corr... |
How is Seinfeld Tvshow still a money earner today? | It airs with commercials. People watch the show and watch the commercials. The advertisers pay to play their ad in front of all those people. The tv station gets that money and gives it to whoever is owed to play it in syndication.Because people still watch it. And when people watch something, it generates revenue. Rer... |
Exactly what will Filibuster Reform do? What is the problem that Obama is trying to solve? Why are people opposing this? | The filibuster reform essentially makes it possible to now break a filibuster of judicial and executive nominees with 51 votes, or a simple majority. They did not change the filibuster for everything, just those two situations. While Obama supports the move, this was lead by Senate Democrats. Essentially the Democrats ... |
Why do compression sleeves help elbow injuries such as tennis elbow? | I’ve been told that it limits the motion of the muscles, therefore reducing strain on the tendons that hold them. TLDR: Your bicep will flop around less in a compression sleeve, so the tendon will be like a tent rope holding a tent down in mild wind versus in a hurricane. |
How are they able to tweet/post videos from Aleppo? | There is a huge gap between the 'war zone' image we get - mostly built from WW2 footage and movies - and what a modern war zone actually looks like. Aleppo isn't some giant crater. There are still parks and even a handful of businesses. Infrastructure is undamaged or mostly undamaged. And the cell network, being wirele... |
How did the octopus do this? | They have special pigment cells on their skin called chromatophores. They use muscles to contract and expand the cells which lead to various colors being seen. They can also use the muscles in their skin to contort pieces of their body, making it look jagged like coral. Also, they have excellent eyesight, which allows ... |
What is the trail an airplane leaves behind when it flies through the sky? | Take a water bottle and drink most of the water. Then, close the cap. Twist the bottle so that it is pressurized and split into two sections. Quickly take off the cap, you will hear a loud POP. In that moment, the air goes from high to low pressure. And if you look at the bottle, it will be emitting a little cloud of w... |
Why, regardless of how big it looks, my cellphone camera always shows the Moon as a tiny dot? | Because the camera is right and your perception is wrong. To test this, next time you see the moon, give it a big thumbs up. Seriously. Hold your arm out and you will see that your thumb easily covers the entire moon. You can even see how much of your thumbnail it would go across. Try making a little sticker the right ... |
Why are females smaller than males in most animal species? | The gender that has multiple mates tends to be the bigger one. In cases where the females breed with multiple males, the female is often larger . "Sexual dimorphism" as this state of affairs is referred to, is much less frequent where animals pair bond for life . Next question is why are polygynous relatiinships more c... |
Who are the Kurds? What is it that makes someone Kurdish? | The kurds are people who live in an area they call Kurdistan, which covers parts of Syria, Turkey, Iraq, and Iran. When the the british divided up the middle east, they didn't care much for how the people there saw themselves, so the kurds don't really have a country. They're grouped together by their ethnic background... |
how do we take pictures of the whole milkyway galaxy when we are in the middle of it? | We can't. If you see a picture of the milky way from the outside, it's either another galaxy or a graphic rendition. [This is how the milky way look from Earth], and is the only direction we can see it from. You can see it easily with your naked eye on a clear night. |
What is the lymphatic system? | Think of the lymph system as a doctor that's constantly making sure small things are taken care of.

Why doesnt Reddit limit the number of posts that are pointing to the same URL. | Some subreddits do this. It's up to the mods at each one to decide what's appropriate for their community. |
Pain Tolerance. Do some people feel less pain than others, or are they simply more psychologically equipped to tolerate it? | Both contribute to how much pain someone feels. Everyone takes the psychological tolerance as a given, so let's talk about the physical aspect of it. You feel sensations from signals that nerves send to your brain. Not all these nerves are the same, they specialize in different sensations. There are some specifically t... |
Why does cereal have double packaging? | Advertisement, the cardboard box has all the information, it also protects the cereal from being crushed and allows for it to be packed neatly and efficiently in the square container. The plastic bag inside ensures freshness and increases the life of the cereal, and therefore letting it be stored for longer, as this is... |
How do video game knock-offs exist? | Simply because they are similar enough to garner interest in people who do play MOBA games like League of Legends but also maintaining enough of a difference so as to not get sued for copyright infringement .
