Answer:

Bone marrow, amniotic fluid, and brain

Explanation:

In the choices, I notice that liver is also a part of Adult stem cells but so are the ones I mentioned.

Adult stem cells are found in small numbers in most adult tissues. To not get confused by embryonic stem cell, adult stem cells are there to replace dead cells throughout the growing process of a human which is also called somatic stem cells but this type of cells helps with the brain, bone and fluid

Aquifers can contain salty, briny, and fresh water. Groundwater can exit the aquifer by the pumping of a well, which is usually called discharge. The answer is aquifers.

Explain the genotypes and phenotypes of skin color. Summarize the relationship between the number of active genes and the color
kotegsom [21]

Human skin color is a polygenic trait, which means that multiple gene loci (with different alleles) are involved in its expression. It has been shown that there more than 350 genetic loci involved in determining skin color. Because of that, there is the enormous number of possible genotypes for the skin color and as a result, the phenotypes vary from the darkest brown to the lightest hues. Different populations have different allele frequencies of genes for human skin color, and the combination of these allele variations brings about complex and continuous variation in skin coloration. Natural skin color can change due to exposure to sunlight (becomes darker) and that is the way it adapts to intense sunlight irradiation (protection against the UV exposure).
