Quite sure C is correct ;) remember that humans are also placental mammals.
The correct answer is stabilizing selection reduces the amount of variation in a trait. disruptive selection increases the amount of variation in a trait.
Stabilizing selection is a type of natural selection in which genetic diversity decreases because natural selection favours an average phenotype and selects against extreme variations.

Disruptive selection is a type of natural selection in which extreme values for a trait are favoured over intermediate values, thus it increases genetic variance.</span>
Answer:
The nitrogen cycle is a repeating cycle of processes during which nitrogen moves through both living and non-living things: the atmosphere, soil, water, plants, animals and bacteria. In order to move through the different parts of the cycle, nitrogen must change forms.
Catalase is an enzyme, O2 and H2O are substrates, and H2O2 is a reactant.
Catalase is a substrate, O2 and H2O are substrates, and H2O2 is an enzyme.
Catalase is a substrate, O2 and H2O are products, and H2O2 is an enzyme.
