What determines the number of eggs a woman is born with? | [

Why do small city and big city people seem to be opposed to each other? | [

why do I always wake up from a dream immediately before I suffer some kind of fatal physical harm (ex. someone shoots me, stabs me, hits me etc.) | [
"It's because your brain is reacting to the fear of the situation. It's like \"Oh! Bad situation. Done!\" so you wake up. Your mind doesn't want to go through that, and you've never experienced it, so you also don't know how to react. :)"

Why do subreddits need moderators when Reddit's voting system filters bad posts/comments? | [

In "landmark" court cases, do they have the ability to change the law when cited in other cases, or is the law still absolute? | [
"Often in \"landmark\" cases it's more a question of interpreting the law than it is changing the law. And then the next time a case like it comes up it is common for courts to lean on the interpretations that came before, especially if it was made by a higher court. This is known as *precedence*"

"Common law is based on precedent. A judge trying a case will look to previous similar cases for guidance on how to rule. Statute law is based on laws in books.

Why do screens have RGB coloured pixels when RYB are the primary colours? | [
