What is one possible message that one cell might send to another cell?

A possible message that one cell could send to another is that it picks up blood sugar to be used as an energy source

Explanation:

Such is the example that happens with hormones, which are chemical substances that originate in a gland, and that being in the blood, give instructions that are attracted even inside the cell. An example of this is the cells found in the pancreas, these cells produce insulin, insulin tells the muscle cell that it must take the blood sugar to use it as an energy source.

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.

so whats the answer
