b. exocrine glands release contents into the bloodstream

c. exocrine glands release contents into ducts

d. endocrine glands release contents into ducts

Question:

After going a long period of time without eating, the intestines release the hormone ghrelin into the bloodstream, which travels to the brain and signals hunger. After eating breakfast, hydrochloric acid and mucus travels through ducts to reach the stomach from the gastric glands and helps break the food down.

B. endocrine glands, because they release their contents into ducts

C. exocrine glands, because they release their contents into the bloodstream

D. endocrine glands, because they release their contents into the bloodstream

A. exocrine glands, because they release their contents into ducts

Explanation:

In photo below

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.
