If angle prq is equiangular, find x and y.

a.
x = 53, y = 74
b.
x = 53, y = 88
c.
x = 74, y = 106
d.
x = 106, y = 44

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.  

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
