Write the equation of the circle centered at (0,1) with radius 15.

Step-by-step explanation:

we know that

The equation of the circle in center radius form is equal to

where

(h,k) is the center of the circle

r is the radius of the circle

In this problem we have

substitute

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.
