The theory is an evolutionary concept that suggests that behaviors that an organism survive are passed on while weak behaviors are lost.

C. Optimality

Explanation:

Was graded correct in ody ssey.

ody ssey ware Biology Unit 3, assignment 1, page 5 ( of lesson printoff ) under EVOLUTION the paragraph after the gif of the jaguars running explains Optimality Theory.  

"This example ( video of slow fat jags dying off) is similar to the passing on of behaviors, and how behaviors evolve due to the greatest fitness for the species.  This is called optimality theory. If a behavior benefits a species more than it costs the species, it will be repeated and passed on for generations. Thus..."

A, and B are from Unit 2, and D is not in the material as relevant and just  junk answer to throw us off.

the binding of the substrate is dictated by the shape of each molecule. side chains on the enzyme interact with the substrate in a specific way, resulting in the making and breaking of bonds.
