Question 7
Which equation results in the same solution as 28 = 2(x + 8) – 4?

28=2x+12

Step-by-step explanation:

combine 2(x+8)

that gets you 2x+16

16-4 is 12

so another equation with the same result is:

28=2x+12

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.
