-- David bought a computer that was 20% off the regular price of 51.080. If an 8% sales
tax was added to the cost of the computer, what was the total price David paid for it?

1.true 2.false? ? i think. .

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.
