Answer:

Bone marrow, amniotic fluid, and brain

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.

slega [8]

Answer:

No, this is not consistent with the principle of independent assortment.

Explanation:

The principle of independent assortment states that alleles from different genes assort independently. This means that if a plant has a genotype Aa Bb, all four alleles (A, a, B, and b) are going to segregate equally, so we will have the following four gametes after meiosis:

- AB

- Ab

- aB

- ab

If the researcher finds that two of the four products are AB, probably there would be a deviation of Mendel's laws.

Nuclear energy use can negatively impact water quality. Please select the best answer from the choices provided T F
MAXImum [283]

The statement is - True.

The production of the nuclear energy by the nuclear reactors requires lot of water. The water's role is to constantly keep cool the reactors because if they overheat there can be a disaster of big proportions.

Because of the heating up of the water the water changes its properties slightly. Those changes have big environmental impact, easily seen in the local flora and fauna in close proximity to the nuclear reactors. There is way to big of a percentage of bad mutations among the flora and fauna where the water is released from the nuclear reactors, where very often there's animals with either more or less extremities, two heads, weird growth and shape of the plants etc.
