B. 3/4(4 x – 8) = 18
C. 2 x + 2 x + 2 = 4 x + 2
D. –3(– x – 2) = 3( x – 2)
E. 1/2( x) = x + 1/2
NEED HELP ASAP!! THANK YOU

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.
