does a flame have organization?

The true question is is a flame alive. I believe it is not because it doesn't develop, however, does it still have cells.

What makes a person gay? Born gay? Genetics? Hormones? Mother's womb? Environment?

There are many things being said. I don't believe that it is a choice so that is way out of the question. Some say its in the hormones or its in the genes but there have been twins where only one has been gay. Others say that the environment inside the mothers womb is also important to determine whether one will be gay or not. Also society/environment would mean that it is a choice? I am really confused and I need to do a research project on homosexuality. I need help with proving that it not a choice so what can I say? I need journal articles and other primary sources to prove this. Any help would be greatful. Thanks

Inbreeding question?

If we had a perfect set of DNA, RNA, whatever. Would imbreeding be a non-issue? Is inbreeding bad because the child has a greater chance of receiving a "bad" set of DNA? Not that I want to have sex with my sister or anything (eeeaaaacccc yuch!) don't get that impression please. I am just curious, because of the whole Adam and Eve thing. Because if their children had children as the Bible says it does they must have inbreed. If we all have a common male ancestor does that mean we are all inbreed. This is more of a funny question than a serious one, so dont get all pissy with me.

Also, my fathers side is from Germany and my mothers side is of mixed European decent. When my (ex)girlfriend and I were taking a genetics course we analyzed our mitochondrial DNA and found we had a common ancestor (must have been a female ancestor because mitochondrial DNA mutations are carried by the female?) But she was Vietnamese, if we had kids that wouldn't be inbreeding right? That would make no sense.

How many "unique" base pairs are there in the human genome?

I've heard that a large fraction of the human genome is the same for all humans. What fraction is left over, i.e. how many base pairs are there that differ between most/all humans?

I wonder because I'm curious how many "possible" configurations (genetically speaking) there are for human beings.

where in the body is blood made?

I have always wondered, what part of the human body creates blood? We lose blood in nose bleeds,cuts etc, so it needs to be replaced, plus we have twice as much volume when we are 18 than we do when we are 13. So in 5 years, the body has created double the blood supply, plus all that lost blood?!
