The graph below shows the concentration of the reactants and products over time for a biochemical reaction that is catalyzed by an enzyme. Which diagram best illustrates how the reaction would be affected if a competitive inhibitor that binds to the enzyme was introduced?

explanation:

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
