The number of cheetahs is declining. How can humans reverse this change in the cheetah population?

a.
Through deforestation

B.
By preserving the habitat

C.
By introducing new predators

D.
By increasing the number of livestock

B (By preserving the habitat)

Explanation:

Option B refers to preserving the habitat, which is an action that someone could take to increase the cheetah population because it would lead to cheetahs having more places to live, grow, and breed. The other options all produce negative outcomes for cheetahs.

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.
