…attacks by widening the bronchial airways. Recreationally, it is used to supply a "boost of energy" or a feeling of greater alertness. College students and drivers often take caffeine to stay awake late into the night. On the other hand, many people take…

…in such a way that will make your head turn. Who really started the idea of quantum physics? Max Planck really got the idea started when he said that energy is quantitized. Later Einstein created the photoelectric effect where he claimed that light energy came from…

…Where possible it's good to buy local. There is lots of reasons for this. * Firstly you're more likely to know more about the goods and the conditions in which they're produced. * Transport and fuel use. It often takes much more energy to transport…

…it is not light, are sound waves. Weather the wave is a sound wave or a light wave it consists of the basic similar parts. These waves all contain wavelength and frequency. A longer wavelength will mean a smaller energy level, as to where a shorter wave length makes…

…connecting it to its surroundings. The processes that the mitochondria make are to break down the high energy organic molecules into smaller more useful packages. The endoplasmic reticulum is a network of tubes and channels that transport…

…, the brightest star in our night sky. The Dog star is a slightly scaled-up version of the Sun, with about twice the mass and 25 times the luminosity. It is an unremarkable object comfortably fusing enough hydrogen into helium in its core to supply the energy radiated…

…for PGE's workers and, in all likelihood, soaring prices. Other critics argued that Enron's actual plan was to cannibalize PGE, in particular its hydropower, which Enron would sell into California's energy market. Enron recruited the noted environmental utility…

…is given out. This is because the amount reactant energy is more than the product energy the difference between this is ?H, therefore some energy has been given out in the form of heat.The energy is given out when forming the bonds between the new water…

…energy and use it to synthesize organic compounds. In green plants, photosynthesis occurs in chloroplasts, that contain the photosynthetic pigments. Photosynthesis occurs by slightly different processes in C3 and C4 plants. Factors which can affect…

…such as cannons, shotguns and rifles, work on the basic idea of conservation of momentum and the change in energy from potential to kinetic. When the trigger is pulled the hammer hits the firing pin. The firing pin then hits the primer which causes the powder…
