Answer:
Artificial selection
Explanation:
The farmer is selecting the most desirable traits and breeding the tomatos to achieve these traits in future generation. A human is artificially altering evolution.
Cellular respiration is a term that describes the biochemical pathway wherein cells release energy and provide the said energy for the important processes of life. Cellular energy can be anaerobic respiration or aerobic respiration.
Aerobic respiration is a process of cell respiration where oxygen is used while anaerobic is a process where organic molecules are used as the last electron acceptors instead of oxygen. In other words, anaerobic respiration is a cellular respiration with no oxygen involved.

A
This should be considered a case of natural selection because humans were not selecting for particular desirable traits.
Explanation:
The individuals in the population who held even the slightest advantage in the tolerance of the oil spill had higher chances of surviving and passing their genes to the next generation. Fishes with low tolerance perished even before getting to maturity. Therefore with each generation, traits for oil tolerance in the population increased by natural selection enabling the population to evolve towards increased intolerance to oil over a period of several generations.
