Answer:

The correct answer is option b, that is, mitosis and cell differentiation.

Explanation:

A zygote refers to the outcome of fertilization. The diploid zygotes go through the process of mitosis and differentiation in order to generate the embryos. The differentiation of cells at the time of embryogenesis is essential for the cell, organ, tissue, and organism identity.  

Once the process of fertilization takes place, that is, the fusion of sperm with the egg, the development of zygote takes place. The zygote differentiates into various kinds of cells by the process of mitosis, initiating the beginning of embryonic differentiation.

Given the following events involved in the regulation of blood volume, which one of the following answers best represents the or
Ad libitum [116K]

Answer:

The correct answer will be-

1. decrease in blood volume

2. secretion of renin from juxtaglomerular apparatus

3. production of angiotensin II

4.  secretion of aldosterone

5. sodium reabsorbed from distal tubules and collecting ducts

Explanation:

The RAAS pathway or Renin-angiotensin II-aldosterone pathway gets activated in the human body to maintain the osmolarity and blood volume.

When the receptors in the blood sense the low volume of water in the body sends signals to the brain which activates the secretion of the renin from the juxtaglomerular cells. Renin helps converts the inactive angiotensin to angiotensin I and II which help reabsorption of sodium ions. This activates the production of aldosterone which increases the reabsorption of the sodium ions into distal and collecting ducts.
