Fill in the blanks below to describe the process of diffusion.Diffusion is the net movement of particles from a region of concentration to a region of concentration until both regions are of concentrations.

Diffusion is:the movement of a substance from a low concentration to a high concentration.the movement of a substance from a high concentration to a low concentration.the movement of a substance from high concentration to a high concentration.the movement of a substance from low concentration to a low concentration.

Which of the following is the best definition of diffusion?The spreading out of particles of a gas, or any substance in solution, resulting in a net movement from an area of higher concentration to an area of lower concentration.The spreading out of particles of a solid, or any substance in a solution, resulting in a net movement from an area of higher concentration to an area of lower concentration.The spreading out of particles of a gas, or any substance in solution, resulting in a net movement from an area of lower concentration to an area of higher concentration.The spreading out of particles of a gas, liquid or solid, resulting in a net movement from an area of higher concentration to an area of lower concentration.

Diffusion occurs when a substance is at aconcentration in one region, and at a lower concentration in another region. This differencein is called the concentration .

Diffusion is the net (overall) movement of particles from an area of high concentration to an area of lower concentration.Question 4Answera.Falseb.True

Diffusion ________.occurs when particles spread from areas where they are less concentrated to areas where they are more concentratedrequires an input of cellular energyproceeds until a dynamic equilibrium is reachedis the result of an energy transformation
