Match the circle equations in general form with their corresponding equations in standard form. x2 + y2 - 4x + 12y - 20 = 0
(x - 6)2 + (y - 4)2 = 56
x² + y² + 6x - y - 10=0
(x - 2)2 + ( + 6)2 = 60
3x2 + 3y2 + 12x + 18y - 15 = 0
(x + 2)2 + (y + 3)2 = 18
5x2 + 5y2 - 10x + 20y - 30 = 0
(x + 1)2 + (- 6)2 = 46
2x2 + 2y2 - 24x – 167 - 8 = 0
x² + y2 + 2x - 12y-g=0

step-by-step explanation:

i hope this : )

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.
