Morgan likes to put the same number of trophies on each shelf of her trophy case. She has a total of 75 trophies, and each shelf holds 15 trophies. This is represented in the equation 15s = 75, where s represents the number of shelves. How many shelves are in Morgan’s bookcase? A. 5

B. 90

C. 60

D. 1,125

A=5

Step-by-step explanation:frac{15s}{15}=frac{75}{15}

divide both sides by 15

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.
