Question

nutrients and waste both enter and leave cells through a process called
a. effusion
b. diffusion
c. fusion
d. emulsion
please select the best answer from the choices provided.
a
b
c
d

Explanation:

To solve this, we analyze each option:

• Option A: Effusion is the escape of gas through a small opening, not related to cell nutrient/waste movement.
• Option B: Diffusion is the movement of particles from high to low concentration, which is how nutrients (e.g., oxygen, glucose) enter cells and waste (e.g., carbon dioxide) leaves cells across the cell membrane.
• Option C: Fusion is the joining of two entities (like cell fusion or nuclear fusion), not for nutrient/waste transport.
• Option D: Emulsion is a mixture of immiscible liquids, irrelevant to cell transport.

Answer:

B. diffusion
