Question

1. if a substance is known to enter a cell by diffusion, what effect would raising the temperature have on the cell? why does it have this effect?

Explanation:

When temperature is raised, the kinetic energy of molecules increases. For a substance entering a cell by diffusion, this means more rapid movement of the substance molecules. The rate of diffusion of the substance into the cell would increase. This is because diffusion is driven by the random motion of molecules (kinetic energy), and higher temperature provides more energy for this motion.

Answer:

Raising the temperature would increase the rate of diffusion of the substance into the cell. Because higher temperature increases the kinetic energy of molecules (including the diffusing substance), leading to more rapid movement and thus faster diffusion.
