... First of all, and most importantly, automobiles are harmful to our environment. Automobiles run on gasoline, which is a mixture derived from petroleum. Gasoline contains hundreds of different hydrocarbons, or compounds containing the chemical elements carbon and hydrogen(Gasoline). When the gas is burned in the engine of the car, several byproducts result. These exhausts include hydrocarbons and oxides of three elements: Carbon, nitrogen, and sulfur(Emissions). Tiny amounts of poisonous trace elements such as lead, cadmium, and nickel also are present. Everything contained in the exhaust affects the environment intensely. Auto engine exhaust contributes ab ...

... of the is the Antibody for specific virus. Dr Stone thinks that the accumulation of stress tips the infected person over into illness. In his study of 72 married white men for a period of 12 weeks, in which they kept daily diaries of their stress. Researchers then measured the subjects' saliva for a substance called secretary immunoglbulin-A antibody, the less they had of it, the more likely it was that the subject would come down with the cold. This may be true according with Dr. Stone, but an argument made by Dr. Gwaltney, "You see, you could have a ton of immunoglobulin-A and you could still get sick. If you don't have a specific antibody for the cold virus that ...

... Information System, cavity trees, cavity restrictors The red-cockaded woodpecker (Picoides borealis) is an endangered species that inhabits pine forests in an historical range from Texas to the Atlantic coast (Jackson, 1986; Reed et al., 1988). Picoides borealis nest in clans or family groups that usually consist of one breeding pair and 2 non-breeding male helpers (Jackson, 1986 ). This group establishes and defends a territory that includes foraging habitat and nesting "cavity trees" (Copeyon et al., 1991; Jackson et al., 1986; Rossell and Gorsira, 1996). Red-cockaded woodpecker clans excavate cavities in living pines, and have established a livin ...

... the Cl atom contains seven valence electrons and Na one. So, as the atoms bond the Na loses its valence electron and Cl gains it making its outer shell complete and it more stable. During this reaction light and heat are given off. This shows an exothermic reaction, which is a release of energy. The electrostatic energy between the two holds them together. Ionic bonds are useful because in a liquid state it can conduct electricity. This is possible because it contains ions. That doesn't conduct electricity in the solid state because there is not enough room within the molecule. The substance produced by this bond is table salt. Other salts, such as CaCl (rock sal ...

... work. This section will address each of these reported negative side-effects. Various studies have claimed that cannabis destroys brain cells. However, several other studies found no structural or neurochemical atrophy in the brain at all. Furthermore, it should be noted that Heath's work was sharply criticized for avoiding safeguards of bias and reporting "changes" that occur normally in the mammalian brain. Wu et al. found a correlation between cannabis use and low sperm counts in human males. This is misleading because a decrease in sperm count has not been shown to have a negative effect on fertility and because the sperm count returns to normal after cannab ...

... but they look almost exactly how they would look if they were full grown with small paws. The wolf would move around by walking, running, or in a big pack with it’s family. The pack can have as much as 36 wolves. Each pack always has two head leaders, one male and the other female. The pack may hunt and go as far as 130 to 13,000 sq. km.(50 to5,000 sq. miles)—and will defend all that land from intruders. The wolf would have soft fur over it body to cover it like a jacket to keep it warm during the winter. The wolf’s eyes are very keen. It can see and hear very well when hunting for the prey. When you hear a wolf howl it is not to scare you. It can be used for ...

... in the future. offers many advantages to both consumers and firms. It is very convenient for consumers as there are no shop hours and orders can be placed any time of the day. also allows companies to have much larger markets, once you are on the Internet you are everywhere. A customer in Japan can buy exactly what a customer in the UK buys from the same electronic store. The capability to purchase products at ease from all over the world would eventually result in the weakening of international boundaries and increased trade between countries. For example when the machinery for one of General Electric's light-bulb factories broke down, GE would invite b ...

... would we preserve our diversity and sense of self? Human cloning also raises many ethical and moral issues. Different religious groups regard cloning in different ways, but most agree on one point. Cloning puts the work of God into our own hands. The creation of life then becomes a manufacturing of duplicates instead of a "creative act of God". It is also important to consider the repercussions of cloning on the cloned individual. Numerous psychological problems may arise if a person discovers that he or she was cloned. How would a child feel if they found out that they were created to be used to donate organs or replace a lost loved one? A cloned child may als ...

... of Radiation. Using the first letter of each main word they named it laser. The laser had everyone excited. The laser was put through many tests and experiments to see what it could do to help modern civilization. At first there weren't many uses for the laser. Then in the 1970's it became very important. It was finally being used in everyday life. As years went on the uses grew in number. Today lasers were being used in a variety of ways. This includes entertainment, military, communication, businesses, measurement, cutting, and more. Measurement: Lasers have become an important part of measurement. A laser is the fastest way to measure long di ...

... 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 Brahe's death Johannes Kepler took the notes and data that Brahe had taken. Kepler came up with the idea the it would be even more mathematically plausible that the orbits of the planets aroun ...
