Area of base=
A)8 square units
B)6 square units
C)12 square units

its 8

Step-by-step explanation:

4 times 2 is 8 and you cant get 6 or 12

A

Step-by-step explanation:

Area of base = length x width = 4 * 2 = 8 square units

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.
