Answer:

look at the pictures

Explanation:

1. If we cross the parental generation which is RR x rr, the probability of the F1 generation to get  rough coat is 100% and they will be a carrier of the recessive trait smooth coat.

Since the phenotypic ratio is 100% heterozygous Rr, in crossing the F1 to get the F2, we will use the genotype Rr. To get the F2, use the cross  Rr x Rr.

The phenotypic ration for F2 is 3:1. There is 75% to get rough coat and 25% smooth. The answer is based on the result on the Punnett square. On the other hand, the genotypic ratio is 1:2:1. There is 25% probability to get RR genotype, 50% Rr, and 25% rr.

2. Since the two parental mice got 6 albino offspring and 5 brown mice offspring, it is approximately 50%. it takes a parental mice who is Brown that is carrying an albino trait crossed with an albino to get offspring with almost the same number. Therefore, the genotype of the brown mice is Aa.

Which of these best explains why mitochondria are called the "powerhouses" of the cell?
Sindrei [870]

<em><u>Answer:</u></em>

They generate chemical energy in the form of ATP.

<u><em>Explanation:</em></u>

Mitochondria are the powerhouses of the cell because they "burn" or break the chemical bonds of glucose to release energy to do work in a cell. This releases energy (ATP) for the cell. The more active a cell (such as a muscle cell), the more mitochondria it will have.

Which part of the nervouds system consists of the brain and spinal cord:
Damm [24]

Answer:

c. CNS

Explanation:

The Central Nervous System (CNS) is responsible for receiving and transmitting information throughout the body. We can define it with the command center that coordinates the activities of the body.  It consists of the brain and spinal cord, which are protected by the skull and spine respectively.

Both structures are reinforced by three connective blades, called meninges. They are: dura mater, arachnoid and pia mater. Between the last two there is a fluid that is responsible for the nutrition of the CNS and the minimization of possible trauma caused by mechanical shocks.
