What can happen when a community becomes isolated from the rest of its species for many generations? a) Competition between individuals will decrease.

b)The community will grow more slowly.

c)A new species can form.

d)There would be no effect on the community.

C) A new species can form.

Explanation:

This is the concept of genetic drift, where a species being isolated gets an unnatural change in the gene pool, and thus can evolve differently.

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.

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves
