9. Which statements about the cone

A. The radius is double the
diameter.
B. The radius is 9 mm.
C. The base area is calculated
using the radius.
D. The volume is one-third the
volume of a cylinder with the
same height and diameter.
E. The volume of the cone is
297 mm

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.  

step-by-step explanation:

b and c are the correct answers.
