A certain pain reliever is taken in 220 mg dosages and has a half-life of 12 hours. The function A = 220(1/2)^1/12
can be used to model this situation, where A is the amount of pain
reliever in milligrams remaining in the body after t hours. According to this function,
which statement is true?
1) Every hour, the amount of pain reliever
remaining is cut in half.
2) In 12 hours, there is no pain reliever
remaining in the body.
3) In 24 hours, there is no pain reliever
remaining in the body.
4) In 12 hours, 110 mg of pain reliever is
remaining

the answer is d. (1.2, -4.7) on edgn

hope this !

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.
