Focusing on which two central themes in biology would help a student understand why animals come in different shapes and sizes?
a. cellular basis for life; homeostasis
b. structure and function; unity and diversity of life
c. matter and energy, homeostasis
d. science as a way of knowing; interdependence of nature

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.
