.... 14, 586) Nuclear power plants generate only about eleven percent of the world's electricity. There are around 316 nuclear power plants in the world that create 213,000 megawatts of electricity. (INFOPEDIA) Radioactive, or nuclear, waste is the by-product of nuclear fission. Fission occurs when atoms' nucleus' split and cause a nuclear reaction. (General Information) When a free neutron splits a nucleus, energy is released along with free neutrons, fission fragments that give off beta rays, and gamma rays. A free neutron from the nucleus that just split splits another nucleus. This process continues on and is called a chain rea .....

.... Everyone, at some point, has experienced the feelings that Wright describes. And with the pronoun ‘we' Wright tells his readers, ‘Yes, I have been through the same things.' This sort of statement is like a token of good will. The readers feel that Wright understands their plight and thus are more likely to listen to what he has to say. With this trust established, Wright moves on to the task of building confidence in his readers. He lives up to his title of science writer by providing various statistics ("As of 1993, 37% of Americans felt they could trust most people, down from 58% in 1960" (4).) and reporting the f .....

.... relatives. These creatures still lived in water, but they had a lot of the terrestrial tetrapod anatomical characteristics. Introduction: Before tetrapods existed, all vertebrates were confined to living in aquatic habitats. The only animals that lived on land were arthropods. Through natural adaptations, the fish developed into amphibians. This colossal stage of change made necessary the evolution of new ways of breathing, locomotion, and reproduction. Paleontologists needed to understand how this transition took place. If the changes in anatomy of the fish developed on land, then they served the same purposes they serve .....

.... diversity would be best served by using a broader range of management tools. Those would include harvesting on federal land - not simply thinning - and increasing the commitment to old-growth attributes on private forest land through techniques such as retaining large trees and snags. As long as federal lands are substantially committed to providing late successional habitat, private forest land can be substantially committed to younger, intensively managed stands, provided critical habitat characteristics are available. The federal lands make up more than 50% to 60% of the forests in Oregon(3). Because timber .....

.... B. Hemophilia A, also known as "Classical Hemophilia" is caused by a factor Vlll deficiency. This is the most common form of hemophilia. The second type of hemophilia, is Hemophilia B, and is sometimes referred to as the "Christmas Disease." Hemophilia B is caused by a factor lX deficiency. Both types of hemophilia are characterized by prolonged episodes of bleeding, especially into joints, muscles, internal organs, or even brain hemorrhaging. Hemophiliacs do not bleed harder of faster than a normal, unaffected person. Instead, they suffer from prolonged bleeding. The reason a hemophiliac will suffer from prolonged .....

.... wire. Calculating Machines and their Inventors: Through the centuries, several mathematical geniuses invented machinesto aid them in their calculations. The machines were never widely used and generally had no direct path to the later development of electronic computers. Example: Pascal: Blaise Pascal (1623-1662) a French matematician, invented the first mechanical adding machine at age 19 in 1642. He became tired of adding long columns of figures while helping his father, who had been appointed administrator of Rouen by Cardenal Richelieu. His device had teen toothed wheels and many gears. Rotating wheels developed s .....

.... because of their appearance. Cirrus clouds are usually white and predict fair weather. Cirrostratus clouds, belonging to the high cloud group, are sheet like thin clouds that usually cover the entire sky. The sun or moon can shine through Cirrostratus clouds. Sometimes, the sun or moon will appear to have a halo around it when in the presence of Cirrostratus. The ice crystals from the cloud refracts the light from the sun or moon, creating a halo. Cirrostratus clouds usually come 12-24 hours before a rain or snow storm. This is especially true if Middle group clouds are associated with it. Cirrocumulus clouds are the last to be .....

.... a month. Without plants to anchor the soil, absorb the water, and recycle the nutrients, the land has become increasingly vulnerable to wind and water erosion. More than 60 percent of the world's rangeland has been damaged by overgrazing during the past half century. Cattle ranching has also been linked to Global Warming. The grain-fed-cattle complex is now a significant factor in the emission of three of the gases that cause the greenhouse effect- methane, carbon dioxide, and nitrous oxides- and is likely to play an even larger role in Global Warming in the coming decades. The burning of fossil fuels accounted for nea .....

.... flow which is when a population may gain or lose alleles by the migration of fertile individuals between populations. This may cause the allele frequencies in a gene pool to change and allow the organism to evolve. The most obvious mechanism would have to be mutation that arises in the gene pool of a population or individual. It is also the original source of the genetic variation that serves as raw material for natural selection. Not only are there mechanisms of evolution, but there is also evidence to prove that these mechanisms are valid and have helped create the genetic variety of species that exists today. Antibiotic resista .....

.... digestive process and what two hormones might be able to alleviate one of the affects. Secretion inhibits stomach movement, emptying, slows secretion of gastric juices and causes bicarbonate to be dumped in from the pancreas and liver to the small intestine. This neutralizes the acid that is coming in. Since this process does not occur there is an increase of emptying of chyme into the small intestine. The small intestine fills and gastric juices keep flowing. The acidity will continue to increase (pH falls). The acid is does not get fully neutralized. Two hormones that can elevate the affects are GIP and CCK. These hormones si .....
