Question

passive transport can be described as...
a process that does not require spending energy.
including facilitated diffusion.
all of these.
including diffusion and osmosis.

Explanation:

Passive transport is a biological process. It doesn't need energy (ATP). It includes simple diffusion (like oxygen moving across a membrane), facilitated diffusion (using transport proteins, e.g., glucose transport in red blood cells), and osmosis (water movement across a semi - permeable membrane). So all the given options (a process that does not require spending energy, including facilitated diffusion, including diffusion and osmosis) are correct.

Answer:

C. all of these.
