Carolyne paid a mechanic x dollars per hour for a 5-hour job plus $70 for parts. the total charge was $320. which equation can be used to determine how much does a mechanic charge per hour?

step-by-step explanation:

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.
