If (x + 2)2 + (y − 5)2 = 25 is the equation of a circle, which statement describes the circle's graph?
a)the center of the circle is (2, 5), and the circle's radius is 25.
b) the center of the circle is (−2, 5), and the circle's radius is 5.
c) the center of the circle is (2, −5), and the circle's radius is 5.
d) the center of the circle is (−2, −5), and the circle's radius is 5.

B.

Step-by-step explanation:

The equation of a circle is (x - h)² + (y - k)² = r²

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

Here we have (x - (-2))² + (y - 5)² = 5², so the center is (-2, 5) and the radius is 5

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.
