Tape a piece of wax paper over the window and it diffuses (spreads) the light. In the body: Oxygen molecules diffuse across cell membranes into cells, and carbon dioxide molecules diffuse out. Both compounds cross the phospholipid bilayer. In a non-living system: Place a small lump of sugar in a cup of tea (or just water). The sugar dissolves, then diffuses throughout the liquid. To see diffusion happening, use not sugar but a small crystal of potassium permanganate in water. The color will gradually disperse through the water.
Diffusion of AIDS is an example of contagious diffusion, where the disease spreads through direct or indirect contact between individuals.
Diffusion is an example of passive transport, like osmosis(the diffusion of water through a membrane).
Diffusion of a concentrated juice in water.
Diffusion Facilitated Diffusion Osmosis
Diffusion of a concentrated juice in water.
An example of contagious diffusion is the spread of Islam from Mecca to all the other countries around it.
No, rain falling from the sky is an example of precipitation, not diffusion. Diffusion is the process by which particles move from an area of high concentration to an area of low concentration.
passive transport
contagious expansion diffusion
The rate of diffusion is determined by the permeability of the membrane and the concentration gradient.
stimulus diffusion
Relocation diffusion
