.... life. Its effects can be most vividly seen, however, in lakes, rivers, and streams and on vegetation. Acidity in water kills virtually all life forms. By the early 1990s tens of thousands of lakes had been destroyed by acid rain. The problem has been most severe in Norway, Sweden, and Canada. The threat posed by acid rain is not limited by geographic boundaries, for prevailing winds carry the pollutants around the globe. For example, much research supports the conclusion that pollution from coal-powered electric generating stations in the midwestern United States is the ultimate cause of the severe acid-rain problem in eastern Canada and the northeastern United S ....

.... other year, with the fledgling being dependent upon its parents through the next breeding season. Like all vultures, s are carrion-eaters. They prefer large dead animals like deer, cattle, and sheep, but will also eat rodents and more rarely, fish. If a meal has been particularly big, they may have to spend hours on the ground or a low branch before they can take off again. s are fastidious birds -- after eating, they clean their heads and necks by rubbing them on grass, rocks, or tree branches. s also bathe frequently and spend hours preening and drying their feathers. s were probably never very numerous in North America. The species once ranged along the entire Pacific Co ....

.... the inner membrane. Cristae extend into a dense material called the matrix, an area which contains RNA, DNA, proteins, ribosomes and range of solutes. This is similar to the contents of the chloroplast stroma and like the chloroplast, the mitochondrion is a semi-autonomous organelles containing the machinery for the production of some of its own proteins. The main function of the mitochondrion is the oxidation of the pyruvate derived from glycolysis and related processes to produce the ATP required to perform cellular work.(Campbell 182-9) Pyruvate, or fatty acids from the breakdown of triglycerides or phospholipids, pass easily through pores in the outer mitochondrial ....

.... must therefore get nutrition from other plants and from animals. When they get their food from living plants or animals, fungi are called parasites. When they get it from dead plant or animal matter, they are called saprophytes. Fungi are very widely distributed throughout the world, particularly in the temperate and tropical regions where there is sufficient moisture for them to grow. They are less likely to be found in dry areas. Some few types of fungi have been reported in Arctic and Antarctic areas (some molds, after all, thrive on refrigerated food). There are about 50,000 known species of . Although any single typical may not be uniform in appearance--a mushroom, ....

.... around the Earth -- not the universe!) then all of his mathematical formulas would become more "aesthetic". Thus, he composed the theory, which led to great controversial book "On the Revolutions of Heavenly Spheres" in which the church was greatly angered. While Copernicus's book was not a revolutionary book, it was, however, a catalyst to make other minds ponder the new Heliocentric theory. After Copernicus's death there were three other scientists which helped credit the Heliocentric theory. Tycho Brahe was the first, he played with the idea that the planets all revolved around the sun, but the sun instead revolved around the Earth(still Geocentric). After Bra ....

.... in a dramatic rise in the ocean temperatures and a depression of the thermocline in the pacific. The thermocline is the layer of water between the warmer, surface zone and the colder deep water zone, in a thermally stratied body of water, in which the temperature decreases rapidly with depth. This depression of the thermocline has great effects on the worlds fishing industry. The cutting of nutrient rich therocline water reduces the growth of algae, which in trun, collapses the food chain. Thus, leaving our worlds subsistence and commercial fishermen with out food and money. With the already descendeing food chain on our earth, the warming water also effects ....

.... In the 17th century, astronomers pointed a new device called the telescope at the heavens and made startling discoveries. But the years since 1959 have amounted to a golden age of solar system exploration. Advancements in rocketry after World War II enabled our machines to break the grip of Earth's gravity and travel to the Moon and to other planets. The United States has sent automated spacecraft, then human-crewed expeditions, to explore the Moon. Our automated machines have orbited and landed on Venus and Mars; explored the Sun's environment; observed comets, and made close-range surveys while flying past Mercury, Jupiter, Saturn, Uranus and Neptune. ....

.... analysis: Digital Imaging Conversion Services Much to the dismay of many in the business world, the arrival of the "paperless office" has been slow coming. Even though the technology exists to almost eliminate paper documents, many businesses have never heard about it. This technology is collectively known as Document Imaging. Imaging has evolved out of the necessity for businesses to manage the ever-increasing amounts of information(Porter- Roth Associates, 1996). The following statistics are evidence of the massive amounts of paper that exist in American business today: Over three trillion documents are currently stored in corporate offices in the U.S. alone and 95 ....
