When Ricardo was 9 years old, he was 56 inches tall. By age 12, he had increased his height by 12%. How tall is he now?

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

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.
