Which of the sets below is a subset of the following set? R= {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}

The answer is A = { 5 , 6 , 7 }

Step-by-step explanation:

Since all the members in A = { 5 , 6 , 7 } are all in the universal set

R= {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}

Which makes A = { 5 , 6 , 7 } a subset.

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.
