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.
Really, these lights contain mercury? Yes, mercury vapor is used to transport electrical currents through the light bulb. Even though the amount of mercury is relatively small, fluorescent lights must be disposed of as hazardous waste. Mercury is a toxic heavy metal that can cause severe damage to the brain, nervous system, kidneys, lungs, and other vital organs. Pregnant women, infants, and young children are especially at risk.
