The Smiths are moving across the country . Mr. Smith leaves 3 hours before Mrs. Smith . If he averages 55 mph and she averages 65 mph , how many hours will it take Mrs. Smith to catch up to Mr. Smith ?

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.  

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

care to share were the trapezoid shown is ?
