Acar enters an interstate highway 20 mi north of a city. the car travels north at an average speed of 58 mph. which equation models the car’s distance d from the city after traveling for h hours?
a.20h+ 58
b.58=20h+d
c. d=58h+20
d.20d=h+58

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.
