mezya [45]

Options for the question are not given. They are as follows :

A.  Mate them and see what color the offspring are—that will be the dominant color

B.  Mate them and see what color the offspring are—the other will be the dominant color

C.  Mate them, and then mate their offspring to see what color the next generation is

D.  Mate them together, and then mate their offspring to see what color the next generation is—the other color will be the dominant color

Answer:

A.  Mate them and see what color the offspring are—that will be the dominant color

Explanation:

Out of the two colors, one will be recessive and one will be dominant. Recessive color will be homozygous since it is only expressed in homozygous condition. It is also given that in this cross the dominant color is also in homozygous condition.

When the guinea pigs mate, the resulting progeny will obtain one dominant allele from the dominant color parent and one recessive allele from the recessive color parent. The progeny will be heterozygous and show the dominant phenotype since the dominant allele will mask the recessive allele. Thus, the color which is visible in their offspring will be the dominant color.

  • memory loss,
  • and thinking ability.

How to reduce the symptoms of these diseases is to use drugs that contain cholinesterase inhibitors.

<h2>Further Explanation </h2>

Acetylcholine is a neurotransmitter that plays an important role in the functioning of the autonomic nervous system. Acetylcholine is one of the most commonly recognized neurotransmitters or nerve stimulating chemicals. These neurotransmitter compounds can be found in the nervous system.

What are all of the energy transformations that take place as sunlight is converted to usable energy within humans
Charra [1.4K]
<span>The energy transformation in the sun is primarily the change of nuclear energy to light energy. 

More Explainable: </span><span>The sun is said to "burn hydrogen" but what that really means is that near the center of the sun there is enough temperature and pressure to cause the fusion of hydrogen nuclei (protons) into helium nuclei (two protons and two neutrons). The fusion (not fission) reaction energy give off energy in a complex way that includes heat and light. The light works its way out from the center of the sun to the surface and eventually out of the surface into space. That is the sunlight we see as well as some light that is outside our range of vision. The light is electromagnetic energy. </span>
