Diffusion is the spontaneous movement of substances from a region of high concentration to a region of low concentration.
Osmosis is the passage of water molecules from a high water concentration region through a selectively permeable membrane to a low water concentration region.
In diffusion, selectively permeable membrane is neither required nor involved while in osmosis, it is involved.
I’m pretty sure it’s the refractory period!!
Hope this helps!
A way we can reduce disadvantages of human made materials is simply by finding new uses for them such as when plastic is molded and used for a container of a liquid.
