Question 1 of 25
To maintain stable internal conditions, cells must get rid of waste. Which
statement best describes the role of the cell membrane in removing waste?
OA. Oxygen molecules move through a layer of phospholipids to exit
the cell.
OB. Active transport is used to force more sugar molecules into the
cell through protein pumps in order to clear the waste.
OC. The cell membrane surrounds waste material outside the cell,
forming a vesicle that the cell ingests.
O D. Carbon dioxide molecules pass freely through the cell membrane
to exit the cell by diffusion.
