Which of the following shows a net for a solid that has 8 faces, 12 vertices and 18 edges?

898.1666667

step-by-step explanation:

5389/6 = 898.1666667

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.  

it would rotate about 180 degrees.
