Therefore, it is quite possible that you are drinking water that was once drunk by dinosaurs.
Why does skin wrinkle in the bathtub?
The outermost layer of the skin swells when it absorbs water. It is tightly attached to the skin underneath, so it compensates for the increased area by wrinkling.

How can so many different plants live in the rainforest?
Of course, it’s pretty challenging to prove that a given factor causes the biodiversity of a rainforest. We can only look at the traits that rainforests and other biodiverse places have in common, and compare that to less-diverse areas.
In other words, our answer to this question is one of “correlation, not causation.” But it’s the best we’ve got!
Name the layers of the Rainforest.
Emergent, Canopy, Understory, Forest Floor
