Aldosterone ________. A) is secreted by the posterior pituitary B) functions to increase sodium reabsorption C) presence increas
Vesnalui [34]

Answer:

Option B) functions to increase sodium reabsorption.

Explanation:

Aldosterone is an hormone secreted by the cortex of the adrenal gland. The adrenal gland is situated at the superior poles of the right and left kidneys.

Aldosterone regulates sodium homeostasis and as such helps to control blood volume and blood pressure.

Aldosterone is secreted in response to decreased blood pressure (hypotension) to increase sodium reabsorption from urine, sweat, and the gut. Also excessive aldosterone levels (too high sodium) can lead to high blood pressure (hypertension).

Which of these pollutants is biodegradable?
vfiekz [6]

Answer:

Food waste

Explanation:

Food waste is an organic compound, unlike the other choices. Organic compounds are biodegradable because living organisms, such as decomposers, have evolved mechanisms of breaking down these large carbon-based compounds/polymers into smaller molecules for energy. Food waste is therefore easily recycled into the environment.

The others do not have naturally occurring organisms to break them down or reduce them. They would, therefore, accumulate in the environment. This is exactly what is happening to plastc pollution. Accumulation of plastic in the environment is due to fact that they are not broken down into simpler molecules by any naturally occurring bacteria or organisms in the environment.
