Yes if a cell is in an isotonic environment materials are moving in and out of the cell membrance at the same rate. However usually molecules diffuse from high to low.

Welcome to the worldwide of osmosis. Diffusion by a semi-permeable membrane. I went to varsity 20 yrs in the past, great Biology Professor, made it very thrilling. He threw quite chalk around the room as an occasion-diffusion. Ask, your instructor or look interior the e book to your different question. Be challenged

Diffusion is the net movement of molecules from an area of high concentration to an area of low concentration. So, technically, diffusion refers to a specific direction, high to low.
During diffusion, molecules are moving in both directions, but the net movement is high to low.

diffusion= passive transport with concentration gradient
simple diffusion= hydrophobic molecules thru membrane only.
facilitated diffusion= hydrophillic molecules via protein forms channel that allows it in.

Dynamic Equilibrium...yes

yes beacause theres a pump to get materials out and a channel to get materials in..... these two are on diff. sides of cell
