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 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.

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 ________.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

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