A 50 mile trip uses 2 gallons of gas. How much gas would you use on a 125 mile trip?

5o mile trip=2 gallon

50÷2=25

1 mile trip=25

so 125÷25=5

5 gallon of gas use

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.
