Part A
What is the rate at which the water was drained from the tank?
A 6 gallons of water per minute
B 11 gallons of water per minute
45 gallons of water per minute
120 gallons of water per minute

your answer would be b

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.
