The vertices of a triangle are p(2,-4), q(-5,3), and r(-1,-2). what are the vertices of the image reflected across the y-axis?

answer: a

step-by-step explanation:

10.2 units

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.
