Jakob is asked to simplify the expression –3a + 4b + 5a + (–7b). He writes: –3a + 4b + 5a + (–7b) = –3a + 5a + 4b + (–7b).

Which property allows him to do this?​

answer

he is simple following addition rule

it would be:

c.parallelogram.

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.
