She introduce... |
Why do we need to have a balanced nutrition while animals dont? | If you're asking why we eat multiple things while animals like, say, a cat only eats meat, it's because we're omnivores.

Chimps, our closest cousins, eat a lot of fruit and pith and ... |
Having just watched a documentary on Chernobyl and it's condition today, why is it that vegetation seems to be mostly unaffected by the fatal radiation which would kill us? | There is almost no fatal radiation in the Chernobyl area any more.

What is the difference between pleading "guilty", "not guilty", and "no contest" in court? | IANAL but . - pleading guilty: yes, yes, I confess, I did it. - pleading not guilty: no, I did not do it, justice system has to proove me guilty. - no contest: Im not saying whether or not I did or didn't do it - the punishment you are likely to give me in this case is better than a long protracted legal battle and esp... |
So what was B:\ drive? Why isn't A:\ drive the primary and how did C:\ become king? | B drive was the second floppy drive.it was a big deal.It meant that you could copy disk to disk without floppy swapping.Floppy swapping was the nightmare of the 80's but it beat the ever loving hell out of using cassette tapes.How many of you remember 8" floppy discs? I only ever saw/used them a couple times very early... |
How does gene activation work? Aren't genes mere blueprints? How does a gene "activate itself"? | If you want just a basic idea of how it works I hope this helps, and it's not super wtf! Ok, so your genes are written in your DNA. Genes code for a protein, but DNA and proteins are written in different languages. So if you need to make a protein, DNA is 'transcripted' into RNA then 'translated' into a protein.The rea... |
If the sun is getting hotter in billions of years does that mean that planets farther from us may become suitable for life (while earth may not). | I'm not sure if you're aware of this, but the gas giants are not habitable worlds. They are planets, but they are *gas giants,* not *terrestrial* worlds. We can only live on the latter. While it's not necessarily impossible that there could be life 'on' gas giants, no organism similar to anything of our world could liv... |
Why do my teeth start moving back to their original position when I don't wear my retainer for a few nights (after 15 years of wearing it)? | My orthodontist has explained this to me a few times.

Why are Google, Microsoft, Yahoo, and Cisco all supporting CISPA when most of them vehemently opposed SOPA? | Because they used the combined might of the internets opinion to protest SOPA because it didn't protect their companies from prosecution.

Why is Jill Stein the one requesting the recount? What is she expecting to get out out of it? | As a third party candidate Jill Stein has nothing to lose, but the authority to ask for a recount. The speculation that Russia hacked or influenced the US elections is rumored, whispered- but serious. If a recount exposes irregularities it would be a story. Then again, Bush didn't win at least twice and he was Presiden... |

How did the Norse religion become part of the Marvel universe? Do marvel now have copyright over a set of Gods? | Comic book creators basically keep pulling crazy ideas out of their ass and hope something sticks. Thor, in my opinion, is a terrible comic book hero concept, especially trying to fit the entirety of Norse mythology in with mutants and aliens and super-scientists. But people bought the comics, so he stuck. Marvel does ... |
How do free softwares like VLC Player make any money? | Some have a community of developers donate their time, others sell support service for their software etc. RedHat makes a linux distribution, but also teaches training for a healthy sum. I'm sure they have other services too. |

How on earth do parking garages underneath skyscrapers support themselves? | The same way the rest of the skyscraper does. You don't seem surprised that the ground floor manages to support the building above it, so why would one floor further down be any different? Try a thought experiment: dig a four-story hole. Build a skyscraper in the bottom with 22 floors. Said tower doesn't collapse, righ... |
If feminists are fighting for gender equality, then why call themselves feminists? | Combination of several answers here.

Many countries place a high tax on alcohol, tobacco, fuel, etc. for their detrimental effects on society. Why isn't confectionary / fast food treated the same? | Part of the problem is that the root causes of obesity aren't well understood by policy-makers or the public. The U.S. Food Pyramid is a good example, a narrative taught to children promoting at its base the very starches and grains that contribute most strongly to adiposity. Some difficult logistical hurdles would nee... |
Is "free X with purchase of Y" a legitimate loophole to sell things typically illegal? (e.g. Free moonshine with every purchase of $30 pen) | It would be considered by a U.S. court to be a 'sham sale' because no reasonable person would pay $30 for a pen .

Why do some helicopters have two rotor blades and others have four ? And what exactly are the benefits of each type? | Generally, you want to have the fewest amount of blades possible.

This is because the tip of the wing is limited to the speed of ... |

Why do we keep using months? Wouldn't it be easier to just count days from 1 to 365 every year instead? | In the same way we eat our food in bitesize pieces rather than wolf it down all in one go; it's easier and less daunting to digest a large number like 365 in smaller pieces. |
If there are sin taxes on items harmful to the body such as alcohol and tobacco products to discourage purchasing them, why aren’t there any on unhealthy foods? | Even if it would be practical to set appropriate taxes on something this complicated, it's unclear if this should be the government's role at all. Laws should certainly shield us from some dangerous situations and substances, but there has to be a balance between protection and intrusiveness. The government isn't my mo... |
Why do we "feel" when someone it's staring at us. | You can't. You just remember the times you thought someone was and turned around and someone was looking at you. The other 99% of the time when no one was looking at you gets forgotten. |

Why are loot crates in video games not declared as gambling? | It is in some countries.

How do car key-fobs work and why do we not see machines that can mass-spoof unlock signals like computer passwords? | What you're thinking of is called brute force algorithm.
