When d is placed on this square, what will the perimeter of the square be?

I can't see a square or a D given with your question.

But to find the perimeter you just have to add the surface of every side of the square.

1. 3

2. 4

3. 1

hope this ! have a great day.

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.
