8. It takes Emory 3 hours to plant 12 flowers. How long should it take her to plant 40 flowers?

9 hours

Step-by-step explanation:

12 times 3 is 40 so 3 times 3 is 9

10

Step-by-step explanation:

takes one hour to plant 4

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

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.
