Why does the control of blood sugar by insulin show negative feedback? Select one:

The release of insulin causes sugar levels to increase even more.

Sugar lowers the levels of insulin back to the normal levels.

The release of insulin brings the sugar levels back to normal.

Insulin mixes with the sugar to prevent it from damaging the cells.

The control of blood sugar (glucose) by insulin is a good example of a negative feedback mechanism. When blood sugar rises, receptors in the body sense a change. In turn, the control center (pancreas) secretes insulin into the blood effectively lowering blood sugar levels.

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.
