I really suck at biology and the textbook doesn't really give me the understanding of the answers. Is there a safe site that I can look things up in biology? I'm currently working on plant structure and function, leaves and flowers.
Thankyou for your answers in advance!

I'm curious as to why, when you hang upside down, why does the blood rush to your head, yet it doesn't rush to your feet when you stand up? Nobody I know can answer this question; we're all stumped.

claming to be athist is the best way to not be accountable for your actions.

but the law states that you cant get energy out of nothing and the hole action/reaction laws also are not related to athistism.

what do you think?

Determine if Rolle's Theorem can be applied to
f(x)=(x²+3x-18)/(x+9) on the interval (-6,3), and if it can, find all numbers c satisfying the conclusion of that theorem.

When I worked it out, I got c=-3,-15 and Rolle's Theorem not applicable. Both turned out to be wrong :( Thanks for the help!
