.... colon. These, too, were afflictions of of the upper classes of old. Why? Because in general the rich refined their food, along with their lives, and so stripped it of an odd but essential ingredient called dietary fibre. Like its fellow carbohydrates, the various types of dietary fibre are the product of sunlight, water and carbon dioxide combining in green plants. Most form part of plant cell walls. But unlike the other carbohydrates, fibres do not break down into sugars in the human digestive system and then course through the blood stream fueling muscles and nerves. Rather, when eaten they tumble intact through the stomach and small intestine and e .....

.... the mass of the comet, is a “dirty snowball” conglomerate of ices and dust. Major proofs of the snowball theory rest on various data. For one, of the observed gases and meteoric particles that are ejected to provide the coma and tails of comets, most of the gases are fragmentary molecules, or radicals, of the most common elements in space: hydrogen, carbon, nitrogen, and oxygen. The radicals, for example, of CH, NH, and OH may be broken away from the stable molecules CH4 (methane), NH3 (ammonia), and H2O (water), which may exist as ices or more complex, very cold compounds in the nucleus. Another fact in support of the snowball theory is that the best-observe .....

.... of the state. The isn't really used for commercial puroses, but is the major watershed and erosion protection in mountainous areas. The is composed of several hundred species of plants, most of which are evergreen shrubs belonging to many plant families such as the rose, oak, heath, buckthorn, and sumac. Common shrubs of the are chamise, scrub oak, mountain lilac, manzanita, and sumac. The plants have evolved to withstand long, dry summers and strong autumn Santa Ana winds that create frequent fires. The leaves of the plants are mostly thickor needle like so it can reduce water loss through evaporation. The chamise, for example, has small, needle-lik .....

.... Hodgkin’s disease. Hodgkin’s disease is different from non-Hodgkin’s disease in that Hodgkin’s disease has a Reed-Sternberg cell present in the areas infected with the cancer. Hodgkin’s disease occurs mainly in people between 15 and 40 or over 55. Non-Hodgkin’s type cancer is much more common than Hodgkin’s disease. Non-Hodgkin’s is a group of over 29 types of . These are classified by the US National Cancer society as aggressive or fast multiplying or indolent, slow multiplying. ( Information Network) The lymphatic system protects the body from agents that could cause disease like bacteria or viruses. Wi .....

.... plant is higher than the cost of running a hydroelectric plant. However, increasing environmental concerns are focusing attention on renewable energy sources. Hydroelectric power generation was made more efficient by the establishment of the Federal Power Commission in 1920. Although additional hydroelectric plants were being built, the simultaneous development of larger and more cost-efficient steam-power plants made it obvious that only very large and costly hydroelectric installations could compete effectively, and that the federal government would have to assume a major share in their construction. Motivated by the search for the multiple use of wa .....

.... cause of this process has not been determined, yet scientists are aware of its reality and harm to humans. Many scientists believe global warming is caused by the increase of carbon dioxide in the Earth's atmosphere, while other scientists believe that the health threat caused by global warming is due to an unusual interaction between cosmic rays and clouds as well as other natural occurring events. The National Weather Service announced that 1998 was the warmest year (on record on average, around the world). A recent tree-ring study indicated that this is the warmest decade in six hundred years (Allen & Herreid, 82). Undeniably, the weather is getting .....

.... in which the insect holds its long, jointed front legs while at rest or waiting for prey. It is also called the "preying" mantis because of its predatory nature. CLASSES Many questions have risen regarding the praying mantis. Such questions include how many different species there are in the animal kingdom. Estimates range from 1500 to 2200 different mantid species WORLDWIDE. The most common figure given, though, is about 1800. The ways the Mantid's are classified in the Animal Kingdom. There is agreement that the collection of mantid species make up the Mantidae family of insects. The Mantidae family, in turn, is part of the order/suborder Manto .....

.... Ronald Reagan announced his 1984 State of the Union address, he included plans for a space station to be in orbit by the mid 1990’s. The idea of having an operable, livable, space station seemed to be inconceivable to everyone who heard that speech. As the ideas for this project began to take off, the main concern was money. How much funding would be necessary to construct a space station? At first, NASA could only work within the agency’s estimated $8.5 billion dollar budget. It was in 1984 when the first construction plan was unveiled, called “Freedom.” A “power tower” concept was designed, which is a long slen .....
