What role does differential reproduction play in natural selection? ! a) some organisms have different reproductive success due to nongenetic traits. b) some organisms have traits that them reach reproductive age. c) different methods of reproduction result in some organisms being genetically altered. d) reproduction varies among organisms due to pathogenic factors. the answer is not a or d based on other posts.

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.

How are proteins and nucleic acids related? they both provide energy. they both carry genetic information. the structure of proteins is determined by nucleic acids. the subunits of nucleic acids are also the subunits of proteins.
