Apyramid with a square base that is 9 cm on a side has a height of 10 cm. the volume of the pyramid is cm3.a0

270 cm³

Step-by-step explanation:

The volume (V) of a pyramid is calculated using the formula

V = × area of base × height

here area of base = 9² = 81 and h = 10, hence

V = × 81 × 10 = 27 × 10 = 270 cm³

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.
