It is important to survival that both unicellular and multicellular organisms are able to maintain homeostasis. Which is not example of organisms maintain homeostasis? A. cells always stay the same.

B. cell division allows or organisms to grow and repair damaged parts.

C. food is made during photosynthesis, and energy is produced from during respiration.

D. materials move into and out of the cells though the cell membrane.

A.cells always stay the same.

Explanation:

Homeostasis is the ability of an organism to maintain a stable internal state despite changes in external conditions. The process of homeostasis is important to the survival of both unicellular and multicellular organisms, as mentioned in this question.

Examples of homeostatic process undergone by organisms include:

- Cell division, which allows organisms to grow and repair their damaged parts.

- Making of food during photosynthesis, and production of energy during cellular respiration. This two processes are necessary for the survival of organisms as one produces food and the other synthesizes energy.

- Movement of materials into and out of the cells though the cell membrane, which is required to bring in needed substances and remove unwanted ones.

However, a cell staying the same does not depict any HOMEOSTATIC PROCESS.

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.
