If a is a symbol and s is a string, define #a(s) to be the number of occurrences of a in s. for example, #1(101100101) = 5. define #a(s) inductively, and then prove by structural induction that for any strings s and t, #a(s· t) = #a(s) + #a(t).

14

step-by-step explanation:

14 x 3 = 42

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.
