Respuesta :

Answer:

The answer is A. I seen it on Quiziz.

Explanation:

The diagram shows that the molecules of red dye moved by diffusion from a higher concentration to a lower concentration in a beaker of water.

What is diffusion?

  • "It is a phenomenon in which a solute moves from its region of higher concentration to a region of lower concentration."
  • It works towards the concentration gradient.
  • "Concentration gradient means difference in the amount of solute present in two areas."

What do you mean by concentration?

  • "The amount of solute present in a mixture is called concentration."

When a dye is put in a beaker of water, it gets evenly distributed through diffusion.

Hence, the correct option is a. molecules of red dye moved by diffusion from a higher concentration to a lower concentration.
