Write an expression for the calculation the difference of 35 and 7 divided by the difference of 9 and 2

the square root of what number? if you add that, then someone will probably answer the question.

i think the answer is b.

step-by-step explanation:

not 100% sure though.

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.
