When an animal starts breaking down body fat to compensate for a caloric deficiency in its diet, are released into the bloodstream.
a. ketones
b. monosaccharides
c. polysacchaides
d. amino acids

A. Ketones

Explanation:

I took the test and 'Amino Acids' was incorrect. Ketones are formed from the breakdown of the tissue and are released into the bloodstream, also known as ketonemia.

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.
