Question

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

Answer 1

the surface-area-to-volume ratio decreases.

Step-by-step 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.
