Which best describe transformation

180 degrees I think

Step-by-step explanation:

When you change sign to the opposite it goes across a number line, so 180 is the opposite

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.

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
