Tom split up the area of a rectangle to help him solve the division equation 930 \div 6=?930÷6=?930, divided by, 6, equals, question mark. He splits the rectangle into parts that are easy to divide by 666:

ege

step-by-step explanation:

egge

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.
