In an experiment, a scientist studied the effect of increased levels of calcium had on a sugar levels in the blood. the scientists changed the calcium levels in people’s blood and them measured their blood sugar levels. the sugar levels in the blood is the? ?

If the calcium levels in blood increases, then there is increase in blood glucose level.

Explanation:

Calcium in blood plays a vital role of homeostasis in regards to level of secretion of insulin. If the calcium level is altered, the homeostasis mechanism is hampered. Several  researches have shown that alteration of serum calcium level affects the metabolism process of carbohydrate and makes the person vulnerable to risks of diabetes mellitus and associated complications. Hence during calcium supplementation, the person's blood glucose level must be considered.

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.
