 Apparatus for demonstrating osmosis
This apparatus for demonstrating osmosis through visking tubing (otherwise known as dialysis tubing) and is widely used in school.
The assembled equipment is inserted into hypotonic, hypertonic, and isotonic solutions and the level on the capillary rises, falls, or stays level accordingly.
The apparatus cannot be stored for more than a few days with the sugar solution inside, because it will go mouldy.

 Whole House Reverse Osmosis
Reverse Osmosis is the process of forcing a solvent from a region of high solute concentration through a membrane to a region of low solute concentration by applying a pressure in excess of the osmotic pressure.
Osmosis is the diffusion of a solvent through a semipermeable membrane from a region of low solute concentration to a region of high solute concentration.
Osmosis is an important topic in biology because it provides the primary means by which water is transported into and out of cells.

When photons travel through a material with a high optical depth and a very short mean free path, their behavior is dominated by scattering and the path of any given photon's path is effectively a random walk.
When heat travels through a material with a thermal gradient (for example, heat traveling through the wall of a coffee mug), the rate of transport is governed by the thermal conductivity and the temperature gradient.

Quantum mechanical methods have been used to identify the nature of the electronic excitations and the mechanism of excitation transfer between the pigments in the photosynthetic system of purple bacteria.
The resulting description has succeeded in predicting observed spectral and kinetic properties nearly quantitatively, thereby demonstrating that complex molecular machinery like the photosynthetic apparatus involving hundreds of pigments and tens of thousands of atoms can be described with accuracy through the application of the laws of physics.
Recently, the long-standing problem of which biophysical mechanism underlies the physiological compass of birds has been solved, dramatically demonstrating that molecular level calculations can be used to predict animal behavior.
