Aresearcher is culturing cells that require oxygen to live in an incubator where the gas levels are carefully regulated. if the researcher observes that the po2 in the incubator is 200 mmhg, what can the researcher deduce about the po2 of her cells?

He can deduce that The pO2 of her cells is less than or equal to 200 mmHg.

Explanation:

Partial pressure of oxygen(pO2) measures the amount of gaseous oxygen  dissolved in the blood. It purposes to measure the effectiveness of the lungs in pulling oxygen from the atmosphere to the lungs.

In the incubator where the gases levels are carefully regulated, a pO2 of 200mmHg on the incubator deduces that the pO2 of her cells is equal or less than 200mmHg.

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.
