<span>CFCs and smog are examples of air pollution.
CFCs (containing atoms of carbon, chlorine and fluorine)are a component of aerosols sprays, refrigerants etc. These chemical compounds are non reactive in the lower atmosphere but the CFCs react with UV radiation in the sunlight and release inorganic chlorine. This chlorine is the main cause of the holes present in the ozone shield (shield that protects us from harmful UV rays) in the polar regions.
Smog refers to the haze or fog that occurs as a result of air pollution (caused by burning of fossil fuels etc)</span>
<span>Chemiosmosis is the movement of ions across a selectively permeable membrane, down their electrochemical gradient. More specifically, it relates to the generation of ATP by the movement of hydrogen ions across a membrane during cellular respiration or photosynthesis.</span>
There are different types of observers. Casual observers differ from scientific observer. Seeing and observing are two different things. Not that everybody seeing is actually observing the thing.
A casual observer just sits back and watch for something to happen while a scientific observer comes up with some hypothesis to work on it.
Tapeworms are known to feed off of their hosts to complete their life cycle. This type of symbiotic relationship is called parasitism. Parasitism is defined as the type of symbiotic relationship wherein only one of the two interacting organisms benefit, at the latter organism's expense. Parasites could either be found inside or outside the host's body. Tapeworms are internal parasites.
