Question

question 6 of 25
which method would a cell use to get rid of waste and maintain
homeostasis?

a. part of the cell membrane surrounds waste particles
and digests them.

b. a vesicle joins with the cell membrane and releases
material from the cell.

c. protein pumps use energy to move large sugar
molecules into the cell via active transport.

d. the cell nucleus directs the ribosomes to make the
waste into proteins that the cell can use.

Explanation:

To solve this, we analyze each option:

• Option A: The cell membrane surrounding and digesting waste is not a typical waste - removal method. Lysosomes are responsible for digestion, not the cell membrane directly.
• Option B: Exocytosis is the process where a vesicle (containing waste or other materials) fuses with the cell membrane and releases the material outside the cell. This is a valid way for cells to get rid of waste and maintain homeostasis.
• Option C: Active transport of sugar into the cell is for bringing in nutrients, not getting rid of waste.
• Option D: The nucleus directing ribosomes to make waste into proteins is incorrect. Ribosomes make proteins from amino acids, and waste is not converted into usable proteins in this way.

Answer:

B. A vesicle joins with the cell membrane and releases material from the cell.
