Evolution is change in a population over time and includes the gene pools of that population. how does biogeographic isolation allow for the change of gene pools over time?
a) biogeographic isolation affects the random changes that take place within gene pools
b) biogeographic isolation affects the changes in gene pools that result from which organisms are breeding
c) biogeographic isolation determines who will win competition for mates
d) biogeographic isolation determines the time that populations will breed

Correct A) bio-geographic isolation affects the random changes that take place within gene pools

The bio-geographic isolation of the species takes place when the geographical barrier work as a distinguishing agent. It takes place when the group of animals, plants and other creatures are not allowed to mate with each other.

The mixing of there genes within the same species is separated by the geographical barrier.

The barrier allows the mating of the species in a different way as compared to the previous one.

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?
