HELP ME AND ILL MARK YOU BRAINLIEST PLEASE IM FAILING

I think the answer is D. You are doubling (x2) the sum (which is addition, so j+8) so you should have 2(j+8)

i dont know sorry

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.
