(x+2)^2 + (y+7)^2 =1296

Step-by-step explanation:

The equation of a circle is given by

(x-h)^2 + (y-k)^2 = r^2

where (h,k) is the center of the circle and r is the radius

(x- -2)^2+ (y- -7)^2 =  36^2

(x+2)^2 + (y+7)^2 =1296

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.
