II.High temperatures
III.Large molecules

A) I only
B) II only
C) I and II
D) II and III
E) I, II, and III

Concentration Gradient

A variation in the concentration of a substance across a space, leading to diffusion or active transport phenomena.

Semipermeable Membrane

A membrane that allows the passage of certain molecules or ions but restricts others, crucial in processes like osmosis.

High Temperatures

Conditions involving elevated temperatures, often influencing chemical reactions or physical states of matter.

  • Gain an understanding of the basic principles behind passive and active mechanisms of transport in cells.

Final Answer :
C
Explanation :
Steep concentration gradients and high temperatures both increase the rate of diffusion through a semipermeable membrane. Large molecules, on the other hand, decrease the rate of diffusion due to their size and the increased likelihood of collisions with the membrane.
