The hormones produced by the endocrine system are a constant that keeps being produced and they balance our body functions.
Explanation:
The wings of owls and quails are similar because they are homologous structures made of same pentdactyle pattern. The wings in both made of the same bone pattern and structure.

The answer should be option B "Enzymes bond with one or more reactants and lower the activation energy needed for the reaction." Enzymes role is to reduce the amount of activation energy it needs in order for it to have the reaction. Enzymes are known to be the ones to speed up a biochemical reaction.
Hope this helps.
