Osmosis and the Visking Tubing

Osmosis is the net movement of water from a high concentration of water to a low concentration of water down a concentration gradient. This is done to equalise the solute concentrations on the two sides. Therefore, in other words, the movement of water is depended on the concentration of dissolved solute in the water (in […]

Chardakov method

All cells require essential materials to ensure their survival. Chemical, physical, and biological processes are used to move these materials inside of cells. Similar processes move waste materials outside of cells. These processes can be passive, occurring as a result of basic physical laws and requiring no outside energy from the cell or they can […]
