I am doing a homework assignment and my brother put parental settings on with a password and this is the only site that works. I just need quick, simple, partially-scientific answers.

1 What do they eat?
2 How do they drink?
3 How do they breath?
4 How do they excrete?
5 How big do they grow?
6 How does reproduction occur?
7 What are the characteristics of the offspring?
8 How do they react to heat and cold?
9 How do they react to danger?
10 How do they compete for food and space to survive?

I don't care if you answer one or all of them. Anyone that at least puts some answer into this will get the Best Answer thingy.

I know that their are more instances of mDNA than nuclear DNA in human cells, but there are more base pairs in the later. So which one wins out for overall genetic material in the body?

I would love to go into a palentology class and learn about creatures that lived in the past. Then we will take field trips as a class and blast ourselves back in time to see the real thing. That would be the ULTIMATE high!

In my biology class, we’re talking about evolution, and EVERYONE in my class believes solely in God but me. None of my friends have any thoughts about it, except to try and convert me to their religion. I feel so alone. I guess what I'm asking is, is there any one out there who DOESN'T believe everything just appeared because God made it? I, personally, think that nothing just appears on earth for no reason, and that it is ridiculous to think so. And no, I am not an atheist, and I do believe in God in some aspects. Please answer with your thoughts. Thanks.
