.... largest group of organic compounds are the hydrocarbons. These compounds are composed only of carbon and hydrogen. Almost all other organic compounds can be considered as derivatives of the hydrocarbons. If the carbon atoms are linked in chains, the compounds are called aliphatic compounds. If the atoms are linked in rings, the compounds are called cyclic compounds. (pg.581, ...ibid...) (Biology Pamphlet) In terms of naming organic compounds the number of carbon-carbon chains are named using the prefixes below: meth- 1 carbon eth- 2 prop- 3 but- 4 pent- 5 hex- .....

.... United States, fewer than five hurricanes, on the average, develop each year in the warm sector of the North Atlantic. Although hurricanes are most noted for their destruction, some parts of the world, especially eastern Asia, rely on them for much of their precipitation. Although numerous tropical storms develop each year, only a few reach hurricane status, which by international agreement requires wind speeds in excess of 119 kilometers per hour and a rotary circulation. Hurricanes average 600 kilometers in diameter, and often extend 12,000 meters above the ocean surface. From the outer edge of the hurricane to the center the baromet .....

.... here include thin cranial walls, small supraorbital ridges, small teeth, small eye sockets, broad, flat foreheads, large cranial volume (above 1200 cc.), low prognathism in the area of the lower face, and a high, vaulted shape in the area of the cranium. “Archaic” features in skull morphology include thick cranial walls, heavy supraorbital ridges, large teeth, large eye sockets, sloping foreheads, low cranial volume (below 1200 cc.), high prognathism in the area of the lower face, and a small, football-shaped cranium. The presence of various mixtures of these modern and archaic traits forms the basis for identifying a fossil as .....

.... of the Superfund. Who is a Potentially Responsible Party? 1.) Owners and operators of waste sites. i) CERCLA actions against dissolved corporations are permissible ii) If one is the owner or operator, liability may attach even if some other party in the past placed hazardous wastes there. ( The seller of a foundry was found liable under CERCLA when it was sold for $25,000, but was appraised at $200,000, suggesting the decision to sell was for disposal of hazardous materials.) A vendor is not an owner if it did not own the property at the time of toxic discharge from the facility. iii) A parent company may be considered .....

.... This was a time when Russia dominated Poland and girls could not attend universities in Poland. Marie’s older sister, Bronya, had already left Poland to study medicine at a university in Paris. Marie sent a portion of her earnings as tutor and governess to Paris to help pay for her older sister’s medical studies. In 1891, when Marie was twenty- four years old, she was invited to live with Bronya upon her completion of medical school. This enabled Marie to enroll at the University of Paris and begin her own dream of becoming a university student. Marie studied mathematics, physics, and chemistry. It was upon enrollment in col .....

.... escape from the normal controls on their growth and start to divide, grow and spread in an uncontolled manner. At first the growth of the cancer occurs very slowly and is usually limited within the prostate gland. Later on in the course of the illness, the prostate gland cells can spread around the body, particulary to the bones where they can paues pain and disability. Estimates show that the cancer may have been growing in some men for up to 10 yearsbefore it causes symptoms and is diagnosed. Some men develop symptoms whereas others do not. In those who that do, the following symptoms are commonly found: BATHROO .....

.... at which species decrease in number and become extinct. It is appalling to know that we are the main cause of this. Over fishing, pollution, over cutting, and an increase in population contribute to this problem. An example of this is the gold mining operation that we saw in the video. While mining, Mercury was dripping into the water. The mercury then got into the fish and into the humans who ate the fish. Biodiversity promotes a healthy environment. Environments rich in biodiversity are stronger and can with stand things such as drought, disease, and other stresses that environments that lack it cannot. In the video, during the .....

.... enamel. Some are disease traits: hemophilia, schizophrenia, cancer, color blindness. Some are politically and religiously charged: skin color, sex. Some traits are not politically and religiously charged: the hardness of the enamel on your teeth, which is controlled by a single gene, whose location is known, and who’s function we do understand. Now scientists are attempting to find proof if the infamous “gay gene�. For years, the gay community has been trying to prove that they were “born gay� and that their lifestyle was not choice. The news media has a ridiculous double standard for the trait "sexual orientation" and every o .....

.... crystals. Though one knows that certain conditions must be present in order for crystals to form; and if some of these conditions are not present or are not perfect, then the formation of the crystal will be disturbed. One may ask him/herself, how is the formation disturbed if only one of the condition would happen to be modified? Most crystals are formed under water or under liquids with similar characters to water; and tend to form under liquids or solutions containing a maximum amount of solute. If the liquid absorbs additional solute, then the solution is supersaturated. If a tiny crystal, called a seed crystal, is added to the s .....

.... he writes. The projections quoted by Prof. Mitchell may not materialize. The European Union will not accept GM products, and this is causing horrendous marketing problems for North American farmers. It is becoming obvious we cannot force Europeans to take such products, even though Canada and the U.S. are using the World Trade Organization (WTO) in an effort to do so. Most large European and British supermarket chains have removed GE products from their shelves, and the largest European food processors (Nestle and Unilever) will no longer use GM products. All this is being reflected in the market -- non-GM foods are now selling at a h .....
