Answer: Disruptive selection
Explanation:
Disruptive selection is a natural selection method, it is also known as diversify selection.
Disruptive selection occurs when natural selection favors both extremes of continuous variation. Over time, the two extreme variations will become more common and the intermediate states will be less common or lost.
Answer:
A. The whale is heterotrophic.
Explanation:
The whale is an aquatic animal that is heterotrophic in nature. Heterotrophic means that this animal lacks the ability to manufacture its own food because it depends on plants and animals as a source of food energy. Since the Whale is dependent on phytoplankton for food, this means that it is not a producer of food and as such is heterotrophic.
Phytoplankton is a marine alga. Algaes are prokaryotes and this means that they are unicellular animals without a membrane-bound nucleus. The Cell wall is mostly a characteristic of plants. So the first option is a perfect description of the whale and not its food source which is the phytoplankton.
Same genus is more closely related. The farther down the list Phylum-Class-Order-Family-Genus-Species you go, the more closely related are the species in that taxon.
Microbial growth requires a minimum in addition to pH, temperature, and other appropriate conditions that are important for the growth of bacteria, molds, and yeasts.
