Question

the difference between an area of high concentration of solute and an area of low concentration of solute is known as
options:
a pressure gradient
an isotonic solution
equilibrium
a concentration gradient
i dont know yet

Explanation:

• A pressure gradient relates to pressure differences, not solute concentration differences, so it's incorrect.
• An isotonic solution means equal solute concentrations, not a difference, so it's incorrect.
• Equilibrium is when concentrations are equal (no gradient), so it's incorrect.
• A concentration gradient is defined as the difference in solute concentration between two areas, which matches the question's description.

Answer:

D. a concentration gradient
