Which of the following statements is true?
mafiozo [28]

Answer:

The correct answer is: D) The kidneys are paired organs that regulate water and electrolyte balance in terrestrial vertebrates.

Explanation:

The kidneys are the organs that control, for example, <u>the volume of body fluid compartments, acid-base balance, and electrolyte concentrations. </u>These organs are also key to <u>eliminate the toxins from the body. </u>

The kidneys are always two (when not is because of a pathology or the surgical removal of one of the two) and are present in vertebrates.

The kidneys <u>do not regulate blood glucose</u>. That is the job of the pancreas through two hormones called insulin and glucagon.

The kidneys <u>do not remove nitrogenous wastes</u> (urea) from the urine, instead they filtrate these wastes from the blood for these to be excreted through urine.
