.... prostate will squeeze the urethra and begin to choke off the urinary flow. This can effect the ablility to urinate and perform sexually. SYMPTOMS OF PROSTATE CANCER Prostate cancer occurs when some of the cells that make up the prostate gland 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 canc .....

.... The organism relies upon the information stored in tits DNA for the management of every biochemical process. The life, growth and unique features of the organism depend on its DNA. The segments of DNA, which have been associated with specific features or functions of an organism, are called genes. Molecular biologists have discovered many enzymes, which change the structure of DNA in living organisms. Some of these enzymes can cut and join strands of DNA. Using such enzymes, scientists learned to cut specific genes from DNA and to build customized DNA using these genes. They also learned about vectors, strands of DNA like viruses, which can infect a cell .....

.... the pollution. Today, large livestock operations look more like animal factories than animal farms. The farms usually consist of several metal barns, each containing several hundred to several thousand animals tightly confined. The floors in the barns are slatted so manure can be flushed away. The manure is pumped into open-air lagoons, which are large, shallow pits dug into the ground, where it is stored until it can be pumped out to irrigate fields. The solid manure sinks to the bottom of the lagoon and is broken down by anaerobic bacteria over several months. The liquid rises to the top and is collected and sprayed over nearby fields. Many problems co .....

.... The equatorial-polar-diameter ratio is 1.12 to 1. Saturn's mass is 5.686 X 10 to the power of 26 kg , or 95.147 times the Earth's. Thus the average density is only 0.69 g/cu cm , which is much less than water, indicating a very deep atmosphere and a very small core. Saturn is one of the giant outer planets, which are characterized by their large size, low density, and corresponding extensive atmospheres. Current models of the interior indicate that below the relatively thin opaque cloud layer is an extensive, clear hydrogen-helium atmosphere. Data on the internal heat flux, the detailed gravity field, and the observed upper-atmosphere hydrogen-helium ratio .....

.... of stone-like corals. Many different organisms, including molluscs, sponges, and worms, help shape reefs, but hard corals and various algae are the major architects. In effect, the corals build limestone, because their skeletons are made of Calcium Carbonate. The skeletons deposited by these corals and other organisms accumulate, along with sand and other debris, to form the backbone of the reef. Over tens of thousands of years, chemical and mechanical changes turn the reef into true rock. The body of a coral animal consists of a polyp, which is the living portion of the coral. A polyp is a hollow, cylindrical structure attached at one end to a surface, t .....

.... is toothpaste containers and also are things such as wood, paper, textile, farm sprays, and Hospital disinfectants. To get pure tin you must first find ore cassiterite or tin stone, a dioxide of tin. The ore cassiterite before smelting and roasting must be crushed into a powder to remove the arsenic and sulfur from the ore cassiterite. When you smelter the tin you must heat it with carbon to remove the zinc, copper, bismuth, and iron from the tin. Tin had been used for many things but tins use is dropping rapidly although tin is still used a lot for plating. Plating such things as electical contacts. Tin is also used as a protective coating. This prote .....

.... people are asked questions either through the use of questionnaires or during an interview. Unlike the experiment approach, the condition and situation in a survey requires no manipulation. All the subject have to do is to answer questions. Good quantitative research is determined by validity and reliability of the research method used (Teevan, 1995:161). Therefo re, the straight correlation study method used in the survey research of "Horatio Alger lives" lack components of validity and reliability. News Article Summary This article entitled "Horatio Alger lives" is basically a survey correlation study done on two distinct social classes; sons of we .....

.... symptoms similar to those of a viral hemorrhagic fever disease. The Ebola Zaire in Kikwit spread quickly, but investigation and control of the outbreak come from a combined effort of medical teams from the U.S. Center for disease Control and Prevention (CDC), the World Health Organization, and from other health organizations in Belgium, France, and South Africa. Since July 1, 1995, 233 deaths have been reported among the 293 cases, in Africa (Garrett 195). Since 1976, researchers have searched for an origin and cure of the virus. Scientist have carried out numerous studies and investigations. Therefore, we now know what the virus is capable of doing, .....
