If, over time, a body of limestone has been squeezed and deformed by great heat and pressure deep beneath the Earth's surface, its structure, and composition change to form a recrystallized limestone known as marble, which can contain over 95% calcium carbonate.

Ostrovityanka [42]

Answer:

R = 0 and no population growth.

Explanation:

Birth rate may be defined as the growth of individual per thousand and death rate determines the death of individual per thousand in a year. The birth and death changes the population dynamics.

The growth rate depends on both the factors that are birth rate and death rate. Here, the birth rate is balanced or equal that replace the offspring father. The change in the population growth is same and the birth and replacement almost cancel out each other. In this case, the birth rate is zero and population do not grow.

Thus, the answer is R = 0 and no population growth.

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.
