I got a 1/2. Which one did I get wrong? Please help

Step-by-step explanation:

Right away, because the scale factor of the dilation is 1/2, which is less than 1, the new surface area should be less than the original.  Simply multiply each side length by 1/2, then recalculate for surface area to get 4*4*6, or 96.

Hope it helps :) and let me know if you want me to elaborate.

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.
