During strenuous exercise, Max's body produces lactic acid and his blood pH begins to decline. His kidneys go to work to preserv
Marat540 [252]

Answer:

c. reabsorbing hydrogen

Explanation:

In this scenario, the individual's kidneys will do all of the following except for reabsorbing hyrdogen. This is because, in a scenario like this where the body pH levels decline the kidneys begin to secrete hydrogen, they do not reabsorb it. It is this process of acid elimination that ultimately causes the body's pH levels to begin rising and restoring themselves to normal. Therefore the answer to this question is c.

Consider the models of cell reproduction. Evaluate the statements and select ALL that are NOT supported by the models.
Novosadov [1.4K]

Answer and Explanation:

The cell division cycle is responsible for increasing and maintaining cell number and size. This cycle is an essential feature of living organisms. There are four phases of cell division mitotic phase (M phase), growth phase 1 (G1), growth phase 2 (G2), and synthesis phase (S). One phase of the cell cycle ends, and the other starts; this is named a phase transition—a unidirectional alteration in the cell cycle phases. During G1, G2, and S phase cell grows and during the M phase cell divides. There are two models of cell reproduction as the clock model and the domino model. The domino model implies that cell division phases must occur in a distinct order and at a definite time. The domino model recommends that the cell cycle events are independent, while the clock model shows that the effectiveness of mitosis entrance was not persuaded by other actions.

Many traits (phenotypes), like eye color, are controlled by multiple genes. If eye color were controlled by the number of genes
mel-nik [20]

Answer:

Explanation:

If there are 5 genes, let us assume that they are in the alternative forms with 2 possible gets for each five... So we have

2 possible gametes for each five = 2 to the power of 5 = 32 gametes

Then genotypes = 3 to the power of 5 = 243

The same also for 10 genes

2 possible gametes for each 10 = 2 to the power of 10 = 1024 gametes

Then genotypes = 3 to the power of 10 = 59,049

The same also for 20 genes

2 possible gametes for each 20 = 2 to the power of 20= 1,048,576

Them genotypes = 3 to the power of 20 = 3,486,784,401
