A female Hymenoepimecis wasp will temporarily paralyze a spider and then lay an egg on the spider’s abdomen. After the paralysis wears off, the spider resumes its normal activity. When the egg hatches, the larva grows by sucking its required nutrients from the spider. What type of relationship exists between the spider and the Hymenoepimecis wasp? A, commensalism
B, mutualism
C, parasitism
D, predator-prey

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.
