Answer 2

Well, Kitty I want to learn it from my friends, what they know, I want to know it in their style, in their way. I am totally new to Biology, so reading a link will be time consuming for me. I appreciate your help.
But if you can explain that in your wordings, then it will be more advantageous to me. :)
