Chantel drew a picture of her dog on a piece of paper that is 12 centimeters long. she used a copy machine to enlarge her drawing. she used the 115% setting to make each new copy. she then used each new copy to generate the next copy, using the same copier setting. enter a recursive formula that will give the length of each new copy. answer is 1.15an-1. i just don't understand how to get that.

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.
