American bison were hunted almost to extinction in the late 1800s. The rapid decrease in (species / population / group) size of the bison has reduced the

genetic (equilibrium / evolution / diversity) of the animals. This kind of

(genetic drift / polygenetic shift / environmental effect) likely occurred

because only a few individuals survived from the original larger population. A

change in (habitat conditions / allele frequencies / genetic equilibrium)

following a large reduction in population size is called a(n) (bottleneck effect /

polygenetic effect / environmental effect).

I need the answer ASAP

i believe the answer is a or 1

a chain link fence because there so tiny even my albino donkey can't get out

there is not 1 highest source of protein, but there are many; meats, fish, poultry, seafood, cheese, eggs, yogurt and milk. the only non complete animal food that is beneficial is gelatin.

for example, no new evidence will demonstrate that the earth does not orbit around the sun (heliocentric theory), or that living things are not made of cells (cell theory), that matter is not composed of atoms, or that the surface of the earth is not divided into solid plates that have moved over geological timescales .
