What is the general form of the equation of a circle with center at (a, b) and radius of length m? A.
x2 + y2 − 2ax − 2by + (a2 + b2 − m2) = 0

B.
x2 + y2 + 2ax + 2by + (a2 + b2 − m2) = 0

C.
x2 + y2 − 2ax − 2by + (a + b − m2) = 0

D.
x2 + y2 + 2ax + 2by + a2 + b2 = -m2

false

step-by-step explanation:

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.
