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 change 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

A) biogeographic isolation affects the random changes that take place within gene pools

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.
