A partial hepatectomy, or the surgical removal of a section of the liver, is often performed to treat tumors or other abnormal growths in the liver. Following a partial hepatectomy, resting liver cells re-enter the cell
cycle, duplicating until the excised portion of the liver has been regenerated.
According to the information above, performing a partial hepatectomy causes liver cells to

thymine. in rna, thymine is replace by uracil

100 dollars because yeah

9.9 years

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.
