36

Step-by-step explanation:

Note that if there are two of the same number multiplied within a root, it becomes a whole number

√18 x √18 = 18

Next, simplify √4.  Factor the number:

√4 = √(2 x 2) = 2

Multiply: 18 x 2 = 36

36 is your answer

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.
