Question

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

Explanation:

• Option A: Osmosis is the movement of water molecules across a semi - permeable membrane from an area of lower solute concentration to an area of higher solute concentration. It is mainly about water movement, not general nutrients and waste.
• Option B: Diffusion is the process by which molecules (including nutrients and waste) move from an area of higher concentration to an area of lower concentration. This can occur across cell membranes (either simple diffusion or facilitated diffusion).
• Option C: Fusion is a process where two or more things combine together. It is not relevant to the movement of nutrients and waste in and out of cells.
• Option D: Osmosis is the same as option A, which is mainly about water.

Answer:

B. Diffusion
