I am pretty sure it is D cytoplasm, because that is the only structure that is in both plant and animal cells.
Earth climate zones are produced
There are five mechanisms involve in diversity of organisms:
genetic drift, mutation, natural selection, gene flow and non random mating.
Explanation:
Genetic drift: It is a mechanism in which frequency of the allele changes within a population due to random sampling. It causes decrease in diversity in organism and can result in new species.
Mutation: Mutation in the genes is the most important reason of diversity.the change in DNA causes introduction of new alleles. Harmful mutations do not le species evolve by delimiting them from reaching sexual maturity.
Gene flow: The allele flow happens when a new gene is introduced into a population either by immigration or random mating. when two populations of same species share genes, variation occurs.
Natural selection: The favourable traits for survival are transferred to the offspring. It allows them to adapt better to the environment. It allows maintenance diversity of organism.
Non random mating: The mating between the individual with varied genotype will result in genetic variation.

A. It is converted to NAD+.
B. It produces CO2 and water.
C. It is taken to the liver and converted back to pyruvate.
D. It reduces FADH2 to FAD+.
