Question

use the information and model to answer the following question. in a lab experiment modeling cell transport, students use agar cubes of different sizes. these cubes are placed in vinegar, and students observe how far the vinegar diffuses into each cube. as vinegar diffuses into each cube, they lose their color. the purpose of the experiment is to model how substances move into cells of different sizes. which of the following best explains how the size of an agar cube affects the rate of diffusion? a vinegar diffuses less into larger cubes because they have a thicker membrane that resists diffusion. b vinegar diffuses farther into larger cubes because they provide more surface area for diffusion. c vinegar diffuses farther into smaller cubes because smaller cells transport nutrients more efficiently. d vinegar diffuses less into smaller cubes because they have less surface area for diffusion.

Explanation:

Diffusion rate is affected by surface - area - to - volume ratio. Smaller agar cubes have a larger surface - area - to - volume ratio, allowing substances like vinegar to diffuse farther into them compared to larger cubes.

Answer:

B. Vinegar diffuses farther into larger cubes because they provide more surface area for diffusion.
