  • Absorptive And Postabsorptive States - 383 words
    Absorptive And Postabsorptive States Absorptive and Postabsorptive States The absorptive state is the time during and right after eating a meal. The absorptive state lasts for four hours, during and after each meal. During this state glucose is the most important energy fuel. Amino acids and fats are used to form degraded protein, and small amounts are used to provide ATP. Metabolites are transformed to fat if they are not used for anabolism. Glucose is formed by the conversion of fructose and galactose, which are stored in the liver from the entrance of monosaccharides. Glucose is released into the blood, or converted to glycogen and fat. Some glucose enters the liver and is used for energy ...

  • Air Pollution - 1,567 words
    Air Pollution Acid rain is a problem that has plagued earth for years. It is poisoning our waters, animals, plants, soil, and more. It is a problem that can not be ignored or it might have catastrophic results on our environment. Acid rain is caused by air pollution, which is due to man-made actions. Scientists have discovered that air pollution from the burning of fossil fuels is the major cause of acid rain. Power plants and factories burn coal and oil, which is used to produce the electricity we need to heat and light our homes and to run our electric appliances. We also burn natural gas, coal, and oil to heat our homes, and our cars, trucks, boats, and airplanes use gasoline to run, whic ...

  • Economy Of China - 645 words
    Economy of China The Peoples Republic of China, the most populous country and third largest in the world, was once the home of a centrally planned economic system; a system that held the country for decades past in an economic and global market limbo. But now, with Chinas attempts to create its new socialist market economy, it is quickly becoming one of the worlds fastest growing economies and is currently the worlds third largest. It is with this economic surge that China has so rapidly been able to expand its presence within the global market. Chinas economic history is very similar to its economic present as for as its intra-country economic commodities. About sixty percent of Chinas work ...

  • Evironmentalism - 2,824 words
    Evironmentalism Evironmentalism: The Next Step Broad Social Change Through Personal Commitment Introduction In the last thirty years, America has witnessed an environmental revolution. New laws like the 1963 Clean Air Act and the 1974 Safe Drinking Water Act forged new ground in political environmentalism. Social phenomena like Earth Day, organized by Dennis Hayes in 1970, and the beginning of large-scale recycling, marked by Oregon's 1972 Bottle Bill, have help change the way Americans think about the environment. As we approach the third millennium, however, we must reconsider our place on the planet and reflect on our efforts and progress towards a sustainable society. As global warming b ...

  • Food - 1,141 words
    Food Athletic Enhancers / In this research paper I will be discussing the ever-popular athletic supplements: Creatine, Androstenedione, and HMB. It has been proven that these supplements when taken in the proper doses will produce phenomenal results in athletic performance. They are taken by athletes of all fields of play in order too give them that extra edge over competition. Creatine monohydrate, which is the number one supplement preferred by athletes, is not a mineral, herb, or steroid. Creatine is a natural nutrient found in the human body and the bodies of most animals. Creatine is also consumed in certain foods, particularly meats and fish, 2.4lbs of uncooked steak contains about fou ...

  • Forests - 1,195 words
    Forests Where Have All the Forests Gone? What is happening to the Earth? Our home is becoming a barren mass of sorrow. Most people in America are blind to what is going on. Could it be that every individual is just turning a cheek the other way. America is faced with an extremely serious problem, and if it is not acted upon there will be nothing left on Earth. Hopefully it will still be able to thrive after the numerous accounts of human destruction. Deforestation in America is a huge problem with devastating affects to humans. The root causes of this travesty are mainly the ongoing need to increase America's economic growth, and the idea of frontierism. These two aspects of deforestation ti ...

  • Fusion - 1,323 words
    ... eating, and the onset of nuclear fusion. The situation in star formation differs in one respect: after gravitational collapse ceases and star begins to expand again due to heat from exoergic nuclear fusion reactions, the expansion is arrested by the gravity force associated with the enormous mass of the star. In a star a state of equilibrium in both size and temperature is achieved. In ICF, by contrast, complete disassembly of fuel occurs. The fusion reaction least difficult to achieve combines a deuteron (the nucleus of the deuterium atom) with a triton (the nucleus of a tritium atom). Both nuclei are isotopes of the hydrogen nucleus and contain a single unit of positive electric charge ...

  • Fusion Energy - 860 words
    Fusion Energy A fusion reaction is one in which two atomic nuclei merge to form a heavier nucleus. this is the process that happens in in the stars. In average stars, like the sun, the process of fusion is converting hydrogen nuclei (or protons) into helium nuclei. There is an enormous amount of kinetic energy and gamma rays released in this process that heat the star's interior, and this realease is what maintains it at the extreamly high temperatures (greater than 10 million K) required to continue the fusion. This process has been making the stars go for billions of years has clear potential as a power source on earth. Once we have started the reaction, Fusion requires no energy and reale ...

  • Fusion: Our Futures Energy - 969 words
    Fusion: Our Future's Energy? Fusion energy seems to be the most promising energy source of the not-too-distant future. It is safe, it uses an energy supply that is so abundant that it will never run out, it gives off harmless waste, and it produces energy comparable to the Earth's sun! But are there any problems with this hopeful energy source? What is Nuclear Fusion? To understand fusion, it is a good idea to know about fission. This is the splitting of the nuclei of atoms into two or more smaller nuclei by bombarding them with neutrons of low energy. It was discovered in the 1930's in an attempt to make transuranium elements (elements with atomic numbers greater than Uranium that do not ex ...
