As mentioned, permeable pavements eliminate impervious areas in a watershed, without sacrificing road and parking space. The permeable pavement itself is only the top layer of a larger permeable ...

The Visking tubing is the selectively permeable membrane. Water moves by osmosis from the high water concentration (dilute solution) in the beaker into the low water concentration (concentrated ...

Osmosis close osmosisThe movement of water molecules across a selectively permeable membrane from a region of higher water concentration to a region of lower water concentration. is the net ...

Small molecules can pass by diffusion, but there is a permeability barrier for larger molecules, with a relative molecular mass of >20–40K, which permits transport of only selective cargo with ...
