Please help (and explain why the answer is right) i'd appreciate that

a is the answer :P

Step-by-step explanation:

slope = rise/run

rise=2

run=4

rise/run= .5

and it intercepts y-axis at -5

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

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.
