Evaluate the expression 7(3 – 2w) + 2 - 3 where w = 5.
O 34
O 30
O -50
0 -28

-50

Step-by-step explanation:

7(3 – 2w) + 2 - 3 where w = 5

21-14w+2-3= -50

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.
