An advantage of electron microscopes compared to light microscopes is that electron microscopes

are inexpensive and commonly used in most biology laboratories.
allow you to view living cells, while light microscopes do not.
have higher resolution that allows you to view smaller specimens.
allow you to view the true colors of the specimens being viewed.

Animal bodies (and even plant bodies for that matter) are complex enough that life couldn't exist without enzymes. enzymes are usually large, complex biological catalysts that are expensive to make. enzymes speed up the rate of chemical reactions without being used up during the reaction (they can be reused many times). they are highly specific in the reactions they regulate. knowing what enzymes are and how they function, why does this explain why complex life forms could not exist if there were no enzymes.
