The answer to the problem 3(6 - 7) + 8 is called a a). difference. b). product. c). quotient. d). sum

a negative exponent is translated as follows:

so, we have

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.
