Langerhan's cells
Explanation:
The Langerhan's cells arise from the bone marrow and migrate to the epidermis. The Langerhan's cells are the body's first line of defense and play a significant role in antigen presentation. They need special stains to be visualized and are primarily found in the stratum spinosum. These are the mesenchymal origin obtained from CD34 positive stem cells of bone marrow and are part of the mononuclear phagocytic system.

Answer:
D) Frequency results from environmental stresses, not dominance.
Explanation:
The allele frequency refers to the amount of frequency of a particular allele in a small population whereas the dominance and recessive are the measure of the effects of the allele on the population which decides the trait of an organism.
The frequency and dominance cannot be correlated with each other as the frequency of the allele in a population is the result of the environmental stress which are random and by chances, whereas the effect of dominance is not random but is the result of the favoured trait for survival.
Thus, Option-D is correct.
