In a car accident, Jane suffered a chest injury that resulted in impaired breathing and respiratory acidosis. How will her body compensate for this imbalance? a) kidneys eliminate bicarbonate ions.
B) kidneys retain bicarbonate ions.
c) kidneys retain hydrogen ions.
d) kidneys eliminate carbon dioxide.

B) kidneys retain bicarbonate ions

Explanation:

Respiratory acidosis involves the inability of the lungs to remove the Carbon dioxide in the body which result in the blood being acidic.

Jane was said to suffer a chest injury that resulted in impaired breathing and respiratory acidosis. Her body will compensate for this imbalance through the kidneys having the ability to retain bicarbonate ions. This helps to reduce the acidity as the ions are alkaline in nature.

b is the best answer for this question.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
