Question

What do the results of the agar blocks indicate about the relationship between cell size and diffusion rate

Answer 1

Answer:

Knowledge of the relationship between the size (volume) of cells and their surface area helps explain the process of diffusion. Agar blocks and cells with the largest surface area to volume ratio (the smaller cubes) have the highest diffusion rates.

Explanation:

Answer 2

Answer:

the surface-area-to-volume ratio decreases.

Explanation:

As the cube size increases, the surface-area-to-volume ratio decreases. The vinegar can only enter the cube through its surface, so as that ratio decreases, the time it takes for diffusion to occur throughout the whole volume increases significantly.
