This picture shows molecules of red dye that have moved. What is this type of movement called?

Back

Simple diffusion; the dye molecules are moving from high to low concentration.

This picture is a representation of what type of transport?

Options: Osmosis, Facilitated diffusion, endocytosis, Simple diffusion

Back

Facilitated diffusion because it is diffusing through a protein from an area of high concentration to low concentration.
