What is the missing value in this table of equivalent ratios? 10 18 15 27 20 36 25 ? 30 54 a. 45 b. 48 c. 50 d. 54

A. 45. The numerator of the ratios is increasing by 5 and the denominator is increasing by 9. 54 - 9 = 45.

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.
