Evaluate the expression described below:
if the number is 4, what is the difference between a number squared and the number?

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.

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.
