A circle has a diameter of 8 yd. What is its circumference? Use 3.14 for it, and do not round your answer. Be sure to include the correct unit in your answer

25.12 yards is the circumference.

all it means is function 3

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.
