Sarah is making nine gingerbread houses. There will be 15 gumdrops on each roof. There will be 3 peppermints on each front. How many gumdrops and peppermints will Sarah need?

no not all of them.

step-by-step explanation:

some of them have a square base.

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.
