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.

Explanation:

• Effusion: Refers to the escape of gas molecules through a tiny hole, not the general movement of nutrients and waste in and out of cells.
• 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 is how many substances enter and leave cells.
• Fusion: Involves the combining of two or more things (like atomic nuclei in nuclear fusion or cells in cell - cell fusion), not the transport of nutrients and waste.
• Emulsion: Is a mixture of two or more liquids that are normally immiscible (e.g., oil and water), not related to cellular transport.

Answer:

B. diffusion
