Select the correct answer. Which equation is true for the value a = 7? A. a +2/a-3) = 15 OB. 4a - 4(14- a) = 24 O C. 2a + 47 = 105 D. 3a + 2(a - 3) = 34 E. 4a - 2a = 18​

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.
