Lawrence has a paperweight in the shape of a triangular prism. The prism is filled with sand and has a volume of 84 cm3. If the paperweight’s area of the base, B, is 12 cm2, what is the height of the triangular prism? A. 7 cm
B. 28 cm
C. 24 cm
D. 6 cm

H=7cm

Step-by-step explanation:

If volume is: V=B*H then H= V:B

So, you get:

H= 84:12

H=7cm

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.
