e. natural selection
Explanation:
The theory of natural selection was coined by Charles Darwin. It is based on the fitness of certain phenotypes to survive changing environments. The difference in phenotypes arises from mutations in the genome due to pressure from the environment [can refer to the cell, interacting cells, population or ecosystem]. These mutations are heritable and become phenotype traits that are common in a surviving population.
B. Muscle cell, also known as myocytes, have more abundant mitochondria than the other cells listed. This is primarily due to the fact that sustained muscular contractions require massive amounts of cellular energy, transported throughout the cell within the phosphate bonds of Adenosine Tri-Phosphate (ATP) molecules. Mitochondria are the cells' organelles that produce ATP, giving them the nickname "energy powerhouses of the cell."
