The circumference of the earth is approximately 24,901 miles. The circumference of the earth's moon is about 72.76% smaller than
the earth's circumference. What is the approximate radius of the earth's moon?
A. 1,079.55 miles
B. 6,783.03 miles
c. 3,391.52 miles
D. 2,883.56 miles

a² + b²= c²

24² + 7² = c²

c= 25

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.
