Why can animals drink dirty water where as humans cannot?
|
[
"Humans can drink dirty water. Until the last century dirty water was just about the only kind of water anyone could get. People often died from waterborne pathogens and pretty much everyone had parasites, but the same is true of most wild animals."

How do people who colorize photos know what color to make things?

[
"Depends on the source photo. For example old photos with advertisement or firetrucks or uniforms, it can be deduced from modern colors what their original color was. Otherwise the colors are just chosen arbitrarily so that they seem realistic and suitable for the given time the photo was taken."

Are humans still being naturally selected?
|
[
"Yes! A concrete example of this: There are large areas of Africa, Southern Europe and surrounds where the population has quite a high proportion of people that suffer from sickle cell anemia. Sickle cell anemia sufferers can't transport oxygen around their body as well as people with normal blood cells. This is obviously a disadvantage. So why are there lots of people in these areas with sickle cell anemia? These areas have a lot of mosquitoes, which pass on malaria. However, sufferers of sickle cell anemia have a natural immunity to malaria. The people with sickle cell anemia tend to survive longer in these areas, and pass on their genes. This is natural selection in process. It is better to have sickle cell anemia than malaria!"

What is credit and why is it necessary?
|
[
"* I'd say yes but the better answer is it can be, because people with bad credit will be able to get (very high interest) options that people with no credit might not be able to. * You build credit by getting credit. You have to get a first card from someone, usually a $250 or $500 limit. If you, for whatever reason, absolutely can't get one, you can get a secured credit card where you have to put down a deposit upfront and that will build your credit. * Having a credit card will cause you to have a credit score to begin with, and paying it on time and keeping the balance reasonable will cause it to go up, which will allow you to have access to more credit. Credit's necessary if you ever want to finance a house or car purchase. If you pay for things with cash, truth is, you can go through your whole life without it. But I don't mind the idea of other people letting me use their money as long as it's cheap enough. /r/personalfinance can go into far more extreme detail but it's closer to ELI45."

|
[
"Can I add to you question why women in Arabic countries wear black robes (burqas)? Wouldn't it make more sense to wear white ones?"

"White is a very neutral color. It won't really 'bother' anyone. Sure, some people will find a red plane or a green one appealing, but many others will dislike it. But who dislikes white? Also, a white color heats up less quickly than e.g. black, reducing the AC costs for the cabin."

What is a Grand Duchess/Duke, who is eligible to become one, and what do they do?
|
[
"A Grand Duke, is usually the ruling monarch of a minor nation. The title is less of senior Duke and more of a junior King. Small provinces changed hands frequently in Europe, often without changing nobility, and often found themselves as independent states. That noble would find themselves as the head of state, more than a mere Duke, but did not want to presume themselves to be the equals of the true European powers. In addition, the nobles under a Grand Duke often enjoyed greater freedom than they would under a King, and would use the title to limit their monarch's power. To become a Grand Duke, you start of as a Duke, wait for your country to go to war, then have your province made into an independent state."

Since cats and dogs have multiple offspring at once, are they considered genetic twins? If not, can dogs and/or cats have twins?
|
[
"yes and or no. So twins are born at the same time and can be identical or fraternal. fraternal twins are genetically siblings, while identical twins have identical DNA. Fraternal twins happen when two separate eggs are released and fertilized very close in time to each other so they both attach to the womb and are born at the same time. This often happens for dogs and cats since their bodies almost always release multiple eggs at the same time. Identical twins happen when one fertilized eggs splits early in development into two eggs and they each grow seperately into a fetus (baby). This can happen with one egg in the womb in the presence of others. So it is possible for a dog or cat to release say 2 eggs both to be fertilized, one of those eggs to split into two, and.....give birth to one fraternal triplet and a pair of identical twins. in this case the first puppy is genetically a sibling to it's two siblings, and the twin puppies are identical genetically to each other."
] |
[
"Genetically? No. The mother might have 6 separate eggs, and they'll get fertilised by 6 separate sperm from the father. It's exactly as if they had 6 separate individual pregnancies. The genetic similarity between two pups from the same litter is the same as the similarity between two pups from a separate litter by the same parents (unless two of the pups happen to be identical twins, which happens when an egg separates and forms two fetuses, just like in humans). Socially? You have the term 'littermate'. In a dog society they might very well say that littermates are more related than siblings from other litters. But that'd just be a cultural thing."

How does this even work from a structural engineering standpoint?
|
[
"I can't comment on that specific structure since it could be a cheat such as you described using internal support of some type. However, such a structure is possible in theory. It is a complex looking version of an arch. Notice how the bricks are higher in the middle? Those bricks rest on the ones below them just like a regular arch. The twist makes it seem more impressive but the idea is the same. The hardest part to keep from falling is the almost straight section at the bottom near the central pillar but if you look you will see that the twist means that the bricks arch up more than any other section as they approach the centre. This gives more stability where it is needed."

Why don't car manufacturers make windshields coated with hydrophobic surfaces so that water rushes off and leaves it dry instead of windshield wipers?
|
[
"To my knowledge, there are no optically clear hydrophobic coatings. additionally, they may not leave the windshield as clear as you might hope to. and it would likely wear off with the constant sandblasting of highway dust. cant wipe away snow, cant use washer fluid. all that aside, good luck convincing the regulators and buyers that they dont need windshield wipers."
] |
[
"There is a drastic difference in air temperature between the inside of your car and the outside air. This temperature difference meets at your windshield. This causes moisture in the hot air to condense into dew or fog on your windshield. To counteract this you turn on your defroster to blow hot air on the windshield and evaporate the moisture off the windshield."

Principle vs law vs theory vs theorem
|
[
"**Law** - a statement based on experimental observations. Laws don't offer explanations. They just state what has been observed repeatedly. They often involve equations. **Theory** - a theory offers an empirical explanation of the world. It is tested through repeated experiments and observations. A theory also offers predictions, which can be tested to falsify a theory. **Theorem** - Theorems are found in math. They are statements that have been proved using math axioms or previously proved statements (theorems). Unlike theories, theorems are deductive. **Principles** - Are similar to laws. They are often said in their non-equation form. With that said, these definitions are often not followed, and there is a lot of overlap in the naming anyway. Often scientific ideas get historical names that don't follow the definitions, and these names stick."

How does snoring work?
|
[
"> Can i tell if i'm snoring? For the most part, no. Even if it suddenly wakes you up, you're unlikely to initially realize that you were woken by the sound of your snoring. > How does snoring work? Snoring is the sound produced when air passes through your pharynx while it's not fully open. In other words the part of your nose/throat that leads to the lungs isn't totally clear, so as air passes through the airway, it's turbulent and causes vibration. It's similar to how a whoopee cushion produces sound as the air passes between two thin layers of rubber and makes them vibrate."

In places on Earth where the Sun doesn't set for many months, do plants keep doing photosynthesis for the entire period the Sun is up?
|
[
"Yes! This is why world record cabbages (and other vegetables) are often grown in Alaska with permanent or near-permanent sunlight. The combination of midnight sun and relatively mild temperatures allows for longer periods of photosynthesis and greater growth. When the temperature gets too high however, photosynthesis declines. Studies of trees of the same species in Alaska as compared with those at lower latitudes show that total annual growth is roughly the same annually, but the Alaskan trees to it far faster in the summer time. Interesting stuff!"
] |
[
"Because the seasons are based mostly on the temperatures. The coldest day of the year isn't actually the shortest day of the year, because it takes time for the sun to start heating things up again. Likewise, the longest day of the year isn't the hottest because the earth retains that heat for a while and the days are still long enough for the heat to build up."

If all fingerprints are unique and earth has 7 billion people. How is it possible that there are 7 billion unique fingerprints? Are the possibilities infinite? Before we are born, how does our DNA know our fingerprint isn't being used by another person?
|

"First off, DNA doesn't directly affect fingerprints in the way you might think. Fingerprints are the result of chemical reactions in the womb; this is why identical twins have different fingerprints. There are way, way more than 7 billion different combinations. Many estimates put it in the 10^20 range or higher. Now, is it possible for two people to have the same fingerprint? Yes, it's possible -- but for law enforcement purposes, it's pretty much a slam dunk, because there will almost *always* be some other evidence or fact that connects them to the crime. It would be hard enough to convince anyone of a one in a bajillion chance of someone with the same fingerprint robbing the bank. It's even harder when you were known to be at the bank the day before casing it out."
] |

"It depends, if you mean will someone else's fingerprint ever register as someone else's, then there is a possibility due to how accurate the fingerprint scanner and software is. If you mean whether two different people will have at least one 100% identical fingerprint, I don't think so."

What is vevo, and why do all the music you tubers use it?
|
[
"**TL;DR** In order to avoid legal troubles of posting music companies' content on their website (Youtube), Google set up VEVO so music companies could control their monetization. [Link](_URL_0_) to a response by a YouTube software engineer who worked on the Vevo launch. > Youtube/Google was in danger of being sued by Sony Music/UMG music. To prevent a potentially devastating lawsuit, Google's CEO (at the time) Eric Schmidt made a deal with Doug Morris, CEO of Sony Music, to build a parallel video platform based on YouTube tech where Sony could control the monetization settings and sell their own ads. Vevo V1 was basically a shell website that hosted an embedded YouTube player which in turn loaded Vevo's own ad module at runtime. This allowed YouTube to keep the music video content, provided a link was present to the 'official' Vevo page (effectively, a rebranded YouTube page.) The videos were still hosted on YouTube."

How is there only one speed of sound? If I shout louder, why is there not more energy leading to a faster speed?
|
[
"Think of throwing a rock in some water. The ripples made move outward at a given speed. Throw a much bigger rock (more energy) and the waves are much bigger but again propagate (move) outward at the same speed. Similar to sound. And light. A bigger light... Say a million candlepower spotlight, doesn't go any faster than the light from a birthday candle. But also note that there IS more than one speed of sound. The speed of sound depends on the density of the air it passes through, and that is about 340 meters per second, 750 miles per hour at sea level. It is slower at higher altitudes where the air is thin and faster through things like water... 4 times faster. It travels 15 times faster in iron. So the speed of sound depends (partly) on the density of the medium - the stuff through which it passes, not how loud you yell. _URL_0_"

"It's the reverse effect of why you, when stationary, hear a whoosh when something zips by you! The whoosh sound is made from displaced air, the faster the displacement the greater the sound. Sound is caused by motion, after all. Ever heard of a sonic boom? When you break the speed of sound, things get... Loud... At any rate, the whoosh you hear while in motion is the sound bouncing off of the object and coming back to your ears sooner than the rebounding sound wave hitting objects further way and returning to your ear. Basically, this is the easiest way to explain sonar!"

Why do most big birds fly away when they see a human but small birds don't really care?
|
[
"Big birds are, ironically, in more danger. The bigger the bird, the longer it takes them to get airborn, and the more likely they are to be on the menu. Small animals generally aren't worth the trouble to catch, especially because they're light and fast. The little birds aren't afraid of you because they know they're not worth your time to catch, and anyway you're too slow to catch them anyway. Larger birds know that they would make a decent meal and if you got close enough you might be fast enough to grab one."

"> i guess he is whatever race the dad impersonating him for his kids is is Yep. The original article by a black woman pointed out that Santa is a fictional character and can be (and has been) portrayed as belonging to any race, then maybe there should be more diverse portrayals in the US media since the non-white demographics are growing. Then the right-wing media fell all over themselves insisting that this fictional character is always and must always be pureblooded lily white. *Their* emotional response is what the kerfuffle is about. FNC and other right-wingers always deny being racist yet are strangely threatened by the idea of non-white fictional characters for children."

What causes the "fingernails on a blackboard" sensation? Why does it feel so horrible?
|
[
"The amygdala is to blame for the cringe. The amygdala associates emotions to memories and stores them in long term memory (hippocampus). There's two theories, one evolutionary, and one physiological. Evolutionary Theory: The sound resembles a cry of alarm at some point in the evolutionary lane. Physiological Theory: Due to the shape of the ear canal, and the frequency of the sound-wave, it causes the frequency to resonate within the human ear canal, causing it to vibrate violently. Both cause a rise in activity of the amygdala, leaving some to suggest that it's recognized as a form of distress signal. On a related note: It has been suggested that the physiological theory possibly correlates to a dog's reaction with high-pitched 'dog' whistles."

As far as I know, it's just a convenience thing. Instead of having to switch on the hotspot feature of your smartphone, your car just has a wifi network you can use when the vehicle is running. If you have an iPhone, you may know the pain of always having to go to Settings to get your mobile hotspot to broadcast. I would have thought the data was more expensive but it looks like OnStar 4G data plans are around $10/GB/month which is reasonable. You can also add your vehicle to your existing family plan if you have AT & T service. I was expecting more of a markup..."

Why does lightning often occur in 'double strikes'?
|
[
"Lightning first comes down in a flurry of haphazard lines trying to find the path of least resistance to the ground. This is called the lead. When the lead finds the path to the ground, you can see a very quick flash move up the lead into the cloud. This return stoke is the full strength of the lightning strike transferring power to the ground, like traffic moving forward at a fresh green light. Once that return stroke makes its trip up the lead, the cloud gives it more energy, making the second flash you see"
] |
[
"If a lightning strike is a sufficient distance from the observer, sound from the strike will not be heard. These silent bolts are called heat lightning. Lightning bolts produce thunder, but the thunder sound does not travel all the way to the observer if the observer is too far away."

Why do some commercials play for a split second and then get skipped? Wouldn't the advertiser get upset?
|
[
"Those flashes of commercials occur in situations where your local station is showing different commercials than the national broadcast that they're receiving. Sometimes the timing gets off, and you get a small snippet of the national broadcast commercial before your station overrides it with their local feed. And no, the advertiser doesn't get upset, because you were never supposed to see their commercial in the first place. Often, it'll be for something like a chain store that doesn't even exist in your area."
] |
[
"If they had commercials at different times, you could just switch to another channel instead of watching commercials. And that wouldn't really benefit the channel you switch to because you can do the same again when their commercials come on. So all channels benefit from keeping their commercials roughly in sync with each other."

why does looking at the sun hurt your eyes but indirectly not so much?
|
[
"Ask your best friend to place their mouth directly in front of your right ear hole and say your name loudly. Then, ask them to place their mouth at your left ear and do the same thing--only this time, instead of having their mouth facing directly at your ear hole, have their mouth face the tip of your nose. Which one \"hurt\" more? The first one, of course. The reason is simple: the pupil of your eye acts exactly like the hole in your ear. It is the tunnel through which the signal (in your ear's case, sound; in your eye's case, light) travels and stimulates your brain. By staring at the sun directly, you are overwhelming your receptors with signal because light is streaming in directly through your pupil--in the same way that your friend's voice felt like it rammed into your right ear. When the light is indirect, you're getting a \"sense\" of the signal without overwhelming your sensory receptors. Or, in the case of your ear, you're hearing the sound without feeling like someone jammed a Q-tip into it."

Where does my local dealer get controlled narcotics like Xanax and Codeine?

That is why up in Harlem, you can buy xanax from a dealer for about 1/2 of pharmacy price, and the dealer is still making a huge profit. in the 90's i had no insurance, and my wife had a xanax script.

When things like galaxies are forming, there are areas with more 'stuff' so things around them get pulled towards it. Since there isn't just one 'lump', different parts of the galaxy will be pulled in different directions. It is unlikely for the momentum of this to cancel out to be exactly 0, so the galaxy picks up a spin."

Or, if you've re-used the password on a site that isn't as good at security as Google or Facebook, some other site gets hacked and they try the same username/password combination elsewhere. There are two things you can do to really protect yourself. First of all, use a strong, unique password, especially for sites that give access to important things, like your email or bank passwords (your password for some random forum probably doesn't need to be that strong if you aren't re-using it). Second, enable two-factor authorization. Two-factor authorization requires something you know (your password) and something you have (either a security key or your phone usually). For example, when I log into my Google account on a computer I've never used before, Google prompts me to enter a passcode that's generated by an app on my phone that changes every 30 seconds. Even if someone guesses my password, they can't get into my account without my phone."

why do British people sound British while talking, but sound like they are from America when singing?
|
[
"When people sing, they tend to enunciate more clearly. This could explain why British people sound more understandable to you when singing. However, there are many British singers who DO use their typical enunciation when singing, and their accent is more identifiable. Take for example the music of Lily Allen, The Clash, Frank Turner, and many other popular musicians. Also, many British rock bands tend to imitate the singing style of their favorite acts, who are often American. As for Americans sounding sing-songy to Brits... I doubt it."
] |
[
"I think it also depends on what British accent you are hearing, cause there are a few. There is the widely recognized ones that people are usually attracted to then there's the the ones that make you wish you could claw your ears out."

Why was cannabis ever made illegal in the first place?
|
[
"There are lots and lots of urban legends and rumors surrounding this impetus of the 1937 Marihuana Tax Act, including pressure from pharmaceutical companies and the paper industry. Although these industries benefited from the act, there's no real evidence that these were the primary factors. In reality, the association of pot with a particular ethnic group was to blame. In the case of pot, the drug was associated with Mexican immigrants, notoriously conveyed in the fact that marijuana, with the silent 'j', became prominent around this time in an effort to associate the drug with the Spanish language, when previously it was often spelled 'marihuana'.

How do weather sites predict weather 30+ days out?
|
[
"They don't. Most only do five, some do ten, and ones that have 30+ just run on averages for those days from past years, factoring in any anomalies, like _URL_0_ does. Even the ten day forecasts are quite inaccurate most of the time if you actually pay attention and compare forecast to actual."
] |
[
"It means that on others days in the past that had the same conditions as today, (such as temperature, air pressure, humidity, wind speed, cloud cover, etc,) it rained on about half of them, and on the other half of those days it didn't rain. So because we can only predict future events based on the past, the best we can do in cases like this is to say that it may rain, it may not. Half the time on days like this it rains, half the time it doesn't. We can't be sure."

Why is it more difficult to run for long periods of time when exercises like biking are just as strenuous?

[
"It's all about practice. You use different muscle groups for different kinds of exercise. Running is *really* hard on your body. You're obviously using your leg muscles, but you're using a whole bunch of other muscles that you may not be aware of. Abs, arms, back, neck, they all play into it with running. Bicycling, you're sitting down, for one. You can also stop peddling for a bit. And you have different gears. Not to diminish from cycling, but it's not really as strenuous as running."

How can Facebook use face recognition software to correctly name thousands of my friends, yet not one hacker can create a bot to decipher a captcha that has a mix of only 26 letters in it?
|
[
"Not many photographs on Facebook are deliberately distorted and obfuscated to make the face just barely recognizable by a human, but that's what's done to the text in captchas."

[
"They have a database of images and what the answer is. It simply checks to see if your answer matches what the database says the it is. Fun fact with captchas - Google's captchas (which show you 2 words - often one more legible than the other) are only half testing you. The first word (the one that's usually more difficult to read) is the actual test - the second one is a word from Google Books that their software couldn't positively identify. So it shows you the word and asks you what it says, so they can make the book transcription better. They're basically using captchas to perform Mechanical Turk style word identification - pretty clever."

Why is the term "Caucasian" applied to all white people, regardless of whether they came from the Caucasus region?
|
[
"In the early 1900s it was believed that white people originated in the Caucasus mountains. At the time, the three \"scientific\" classifications were Caucasoid, Negroid, and Mongoloid. (Some people still use mongoloid or \"mongo\" as an insult to this day.) There's no real scientific basis to this, and no way to draw a dividing line. If you were to divide races scientifically by amount of genetic variation, you'd find it looked something more like this: * non-Bantu sub-Saharan people like the Bushmen and the Mbuti (four or five races) * everybody else Which shouldn't be surprising, since the non-Africans descended from a few waves of migrants who only carried a small amount of humanity's total genetic variation. (edit: a word.)"

How people program "Angry Birds"-like physics and collision detection.

This is not real code, this is just so you can understand basically what's happening. object Bird { centerX = 50 centerY = 50 width = 20 height = 20 } building.frontEdge = 100 (X coordinate) while (inAir) { centerX = centerX + (whatever physics calculations here) centerY = centerY + (same. Calculations to move the object in an arc) bird.frontEdge = center + (width / 2) if (bird.frontEdge > = building.frontEgde) (If the front edge of the bird is greater than or equal to the front edge of the building on an x-coordinate graph) { do whatever for a collision } In reality, it's much more complicated, as the objects aren't prefect squares, and the physics calculations are more defined, but that's basically what happens. The bird is kept track of, where its shape is defined as different coordinates. If any of the coordinates are the same as the coordinates of the object it's supposed to hit, then a collision has happened."

What exactly makes a 3-in-1 bodywash/shampoo/conditioner different from its individual counterparts (or even the 2-in-1 shampoo/conditioner)?
|
[
"The fact that it only works as one of those at best. Usually it’s just body wash with maybe some additives and fancy marketing. If you want to treat your skin and hair well, use three separate products that actually do their job. Every persons skin and hair is different and the idea of a one-fits-all and all-in-one product is ridiculous. Especially the shampoo-conditioner combo is nonsense since those two products literally do opposite things. Shampoo cleans your hair from the oils that accumulate on it and conditioner puts some amount of oil and moisture back on it."
] |
[
"Not very well, is the short answer. Cosmetics companies did find conditioning chemicals that stay on the hair when used in a 2-in-1, possibly they're more resistant to the cleaning chemicals than natural oils. But they're still not able to match what a separate shampoo and conditioner can do, and product buildup in your hair can be a problem. On the other hand it's usually better than shampoo alone. Of course there are plenty of people who swear by conditioner-only, water-only, and even no hairwashing at all. Do whatever seems to work for your own hair."

The concept of white privilege to someone like me who is not white
|
[
"White privilege does not mean that ever single white person enjoys advantages over every single person of other ethnicities. It's mostly referring to two things: * White neighborhoods are, in general, better off economically than minority communities - and tend to receive better education/police services. * Racism is subtle, but real. Little things like promotions at work, traffic stops, you name it - individually they're often in grey areas but in aggregate they show a clear preference towards whites. Those sort of things are also somewhat regional. Some regions of the US are fairly integrated and more beyond that stuff, some *way* less so. A wealthy family immigrating into a well to do integrated neighborhood in SoCal or something probably won't see that, but that's not exactly the typical experience of immigrants from Latin America."

How are rock songs constructed?
|
[
"> How exactly does the guitar interact with the bass, rhythm and vocals. Generally speaking, one instrument (most often the guitar) plays a lead melody, while all other instrumentation and vocals play harmonically-compatible parts which *support* that melody. On their own these supportive instruments do not play parts that could be considered distinct melodies, as they're designed to accent the lead melody. More complex rock music, and a great deal of music from other genres (such as classical or technical death metal), will feature instruments playing completely *separate* but harmonically-compatible melodies, each of which could stand on its own as a distinct melody. If you require more information than that, I don't think your question is really ELI5 appropriate. You'll need to start learning music theory thoroughly, and from the ground-up.

"Well usually we see it in movies in the context of the first volley against a force moving towards the wall. In that case the commander can simply say 'on my mark' if they want the arrows to start only when the enemy forces are close enough to get a reasonable hit on with the arrows. Also it's a lot more devastating to morale to have them all hit at once. The perception of a well-coordinated enemy is itself disheartening but also it means you're getting this rain of grievous injuries all hitting together so from the perspective on an enemy foot soldier there's just waves of death causing quite a few of the guys around him to start bleeding out all at once.

Some of the first text-to-speech software was installed on his chair, and because that voice has become tied to him, he's left it even though it sounds quite robotic and there's better sounding solutions these days.

Why are farmers struggling financially when there are more people than ever before to feed, people eat more on average than ever before, we know more about the science of agriculture than ever before, and there is more advanced machinery for planting / harvesting than ever before?

[
"Automation is eliminating most of the simple jobs for farmers. A typical farm machine does the work of 40 laborers. So now being a farmer means you need a ton of money to operate a fleet of expensive machines."

"The biggest problem with world hunger isn't that we don't produce enough food, it's that we can't get it to the people who need it. Corrupt governments, greedy, war & lack of infrastructure are far bigger issues than not having enough food to go around."

Why do judges and lawyers in the UK still wear those ridiculous wigs in court?
|
[
"Why do priests wear their collars backwards? Why do businessmen wear a strip of fabric around their necks that have no function? Why do chefs wear that puffy hat (when any hat would work)? I think labeling something as \"ridiculous is a bit subjective"

"they were called liripipes. Most people believe it was just a fashion trend at the time, one that was capitalized by modern artists/video games/what have you whenever they want to make something look \"medieval.\" There are a few manuscripts from around the fourteenth century in which people complain about how ridiculous the liripipes look, and speculating that soon people will be wearing hoods that hang down to their feet in back. It's kind of like old people complaining about saggy pants."

How do animal eggs get their nutrients?
|
[
"The yolk contains the nutrients needed for the animal to grow. Think of the yolk as the place a of the egg. The fetus is attached by an umbilical cord to the yolk. By the time the animal is fully grown, the yolk nutrients have been used up."
] |
[
"Nope A chicken egg contains all the nutrients that the embryo will need to form into a baby chicken, there is no resupply so it has to have all of the food within it A human egg is just a single cell that gets fertilized, it has no nutrients in it because it will implant on the uterine wall and be fed by the placenta until a baby person is ready. With no nutrients you would find a large human egg would give you a very watery and bland omelette with none of the delicious fats, proteins, and other flavors you get from a chicken egg"

What happens to people who were previously charged with illegal possession of marijuana after a new law legalizes it?
|
[
"It depends on the exact nature of the new law. All else being equal, they may still be convicted, or if already convicted may still be imprisoned, because they broke the law *as it stood at the time*. However, recognising that this is kind of silly where a law is introduced that basically says \"welp, we shouldn't have had that other law in the first place\", legislatures may put provisions in the law that cause pending prosecutions to be dropped, and may even automatically commute the sentences of people already convicted. This, though, is by no means guaranteed. All of that actually applies to *anything* that becomes legal after having previously been legal, not just possession of cannabis."
] |
[
"1. Marijuana is not actually legal in Texas yet. The bill has not passed, only the people who decide what lawmakers are allowed to vote on said that they could vote on it. 2. Four states have legalized Marijuana. 3. The move is driven by small-government conservatives who believe that it's not up to the state to decide if God made a mistake when he made marijuana. 4. The bill would put everyone in state jail for marijuana stuff on parole, effective immediately, with a parole officer watching them. 5. The bill will have it be illegal for minors to use the drug without parental supervision."
