a. cancerous cells are prevented from dividing and have inhibited growth patterns.
b. cancerous cells possess defects that make proteins required for cell growth inactive and tumor suppressor genes active.
c. cancerous cells lack the ability to carry out cellular respiration and photosynthesis.
d. cancerous cells possess defects that make proteins

Cancerous cells possess defects that make proteins required for cell growth active and tumor suppressor genes inactive.

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.
