Quadrilateral abcd is reflected across the y-axis and translated 1 unit down to create quadrilateral efgh .

abcd≅efgh

what statement about quadrilateral efgh is true?

gh∥gf

gh∥fe

gf∥he

fe∥he

it would be:

c.parallelogram.

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.
