The following series are geometric series or a sum of two geometric series. determine whether each series converges or not. for the series which converge, enter the sum of the series. for the series which diverges enter "div" (without quotes). (a) ∑n=1∞10n9n= , (b) ∑n=2∞13n= , (c) ∑n=0∞3n52n+1= , (d) ∑n=5∞9n10n= , (e) ∑n=1∞7n7n+4= , (f) ∑n=1∞9n+3n10n=

109 is the nearest whole number/final 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.
