2. Explain how the surface area and volume of cells affect the rate of exchange of materials in and out of cells in multicellular organisms. (2 points)

what's the rest of the question

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.
