(quote)(Someone who has a real background in biology feel free to kick my butt if I'm grossly mistaken anywhere here. I know I'm explaining it poorly. I had 6 semesters of biology in high school, but yeah, it was high school biology, with additions from the popular science magazines here and there, so I might well have some gaping holes in my argument!)(unquote)
seems to agree with what i learned in 7th grade biology!
