Leah earned a score of 60 on Exam A that had a mean of 100 and a standard deviation of 20. She is about to take Exam B that has a mean of 43 and a standard

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.  

c - they will have the same distribution
