A process that requires no energy input is passive. One passive process used by materials crossing a cell membrane is diffusion. Examples: oxygen diffuses through the phos â¦ pholipid bilayer into a cell that is respiring aerobically.carbon dioxide diffuses out of cells through the phospholipid bilayer. Facilitated diffusion (diffusion through transport proteins: channel and carrier proteins) is a form of diffusion, and so it is also passive.
All fluorescent lamps and tubes must be recycled, or taken to a household hazardous waste disposal facility, a universal waste handler (e.g., storage facility or broker), or an authorized recycling facility. See a list of all wastes banned from the trash.
A fluorescent lamp or a fluorescent tube is a low pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. An electric current in the gas excites mercury vapor which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the bulb to glow.he light output and performance of fluorescent lamps is critically affected by the temperature of the bulb wall and its effect on the partial pressure of mercury vapor within the lamp. Each lamp contains a small amount of mercury, which must vaporize to support the lamp current and generate light.
