Select the statement that best justifies the conclusion based on the given information. definition of bisector. definition of midpoint. if two lines intersect, then their intersection is exactly one point. through any two different points, exactly one line exists.

the answer is definition of bisector.

i got this right on my lesson.

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.
