Why do predator populations follow the cycles of prey populations? A. The predators carefully note how much prey remains and only have as many offspring as they can feed.
B. The predators spend so much time around their prey they begin to have similar birthing rates.
C. Because, as the amount of prey declines there is not enough food for all of the predators, and their
population declines as well.
OD. It is unknown why predator populations follow the cycles of prey, but many scientists are studying it.

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.

the endomembrane system i think

the titanic would be the correct answer
