Breeding programs and habitat preserves have been established as an effort to protect the florida panther from extinction. studies indicate that a minimum of 50 adult panthers are needed in order to have a self-sustaining population, which is one that does not need to be supplemented with breeding programs. if a wild population of 40 panthers were left alone, which would most likely happen to the panther population?

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.
