Question

which process is characterized by the movement of particles from an area of high concentration to an area of low concentration across the plasma membrane without the use of energy?
hypertonic transport
active transport
passive transport
dynamic equilibrium

Explanation:

Passive transport is the movement of particles from an area of high concentration to an area of low concentration across the plasma membrane without using energy. Hypertonic transport is not a standard term for this process. Active transport requires energy. Dynamic equilibrium is a state, not a transport process.

Answer:

C. passive transport
