Answer 1

The correct option is B

Regulation of vitamin A synthesis

The basic functions of the kidneys include:

Regulation of extracellular fluid volume. The kidneys work to ensure that there's an adequate quantity of plasma so as to keep blood flowing to vital organs.

Regulation of osmolarity.

Regulation of ion concentrations.

Regulation of pH.

Excretion of wastes and toxins.

Production of hormones.

All higher animals, including humans, must obtain vitamin A from the diet since they lack the ability to synthesize it in the body.
