Which of these are units of volume cm2 kg2 cubic metre m2

None.

Step-by-step explanation:

For volume it would be cm3 (centimeters CUBED). For whatever type of measurement it is, it will always be cubed for volume.

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.
