Question

1) What does the term “concentration gradient" mean?
Answered by GPT 3.5
The term "concentration gradient" refers to the gradual change in the concentration of a substance from an area of higher concentration to an area of lower concentration. It is usually observed in the context of diffusion, where molecules or ions move from an area of higher concentration to an area of lower concentration until equilibrium is reached. The concentration gradient provides the driving force for this movement.
