Cleaning up after the exxon valdez was a mistake
Cleaning up after the exxon valdez was a mistake Cleaning Up after the Exxon Valdez Was A Mistake Through many hours of research I have determined that the spill cleaning techniques used to clean the Prince William Sound area of Alaska did more harm than leaving the oil where it was. The Alaskan oil spill has become the most studied and managed event of its kind. Although there is not much that can be done about the marine life that came into direct contact with the crude oil, the ge...

Chlamydial infection
Chlamydial infection Chlamydia Chlamydial infection is the most common bacterial sexually transmitted disease in the United States today. The U.S. Centers for Disease Control and Prevention estimates that more than 4 million new cases occur each year. The highest rates of chlamydial infection are in 15 to 19-year old adolescents regardless of demographics or location. Pelvic inflammatory disease (PID), a serious complication of chlamydial infection, has emerged as a major cause of inferti...
Chromatography
Chromatography Chromatography is a separation technique in which the mixture to be separated is dissolved in a solvent and the resulting solution, often called the mobile phase, is then passed through or over another material, the stationary phase. The separation of the original mixture depends on how strongly each component is attracted to the stationary phase. Substances that are attracted strongly to the stationary phase will be retarded and not move alone with the mobile phase. Weakly at...
Chromosome Probes at the Unive
Chromosome Probes at the Unive Chromosome Probes at the University of Toronto Uploaded: November 29, 1986. Sensitive chromosome probes recently discovered by a University of Toronto geneticist will make it easier to detect certain types of genetic and prenatal diseases, as well as being used to determine paternity and provide forensic evidence in criminal cases. Probes are short pieces of DNA which bind to, and actually pinpoint, particular sites on a chromosome. Because these new pr...

Chrones disease
Chrones disease Crohn's Disease (Regional ileitis) Intro (use part or all of this if your need it for the introduction) Crohn's disease is named after the physician who described the disease in a paper written in 1972. It is also called Morbus Crohn's, Granulomatous enteritis, Regional enteritis, or Terminal ileitis. Attacks of Crohn's disease affects patients in their teens or early twenties, and tends to recur throughout the individual's life. It is usually chronic, with recu...
Chinese Shih Poetry and Philos
Chinese Shih Poetry and Philos Since the beginning of time, man has sought to explain the world around him. This is called philosophy, a Greek word which means "love of wisdom." However, over the millennia it has come to mean much more. The philosophies of the ancient Chinese people, whether they explain nature or present ways to live a just life, became so complex that simple prose could not suitably express their meaning. Yet paradoxically, the simpler, less exact form of poetry does p...

Chlamydia 2
Chlamydia 2 Chlamydia Chlamydia is caused by the bacterium Chlamydia trachomatis, hence the name; Chlamydia The word chlamys is Greek for "cloak draped around the shoulder.� This describes how the intracytoplasmic inclusions caused by the bacterium are "draped" around the infected cell's nucleus. Scientists discovered the organism in 1907, although it probably has been infecting people for hundreds of years. Because the symptoms of the disease resemble other pathologies, chlamydia ...
Chlamydia
Chlamydia Chlamydia Chlamydia is the most common sexually transmitted infection in the United States. It strikes about 4 million people a year in the U.S.. 100,000 women become infertile each year from a pelvic inflammatory disease (PID), which plugs up or scars the filopian tubes, so the egg can�t reach the uterus. 45% of sexually active teenagers are exposed to the disease at least once. Clamydia is caused by a bacterium, named chlamydia trachomatis. The pathogen enters the body ...
Chesapeake bay pollution
Chesapeake bay pollution A Look at the Chesapeake Bay The Chesapeake Bay is America's largest estuary and one of the world�s most productive. The Bay is home to over 2,700 species. It draws water from over 150 rivers, streams, and creaks, receiving roughly 70,000 cubic feet of water every second. That water reflects the surrounding land use activities of the District of Columbia, parts of New York, Pennsylvania, Delaware, Maryland, Virginia, and West Virginia. A total of about 15 millio...
Chicken pox with works cited
Chicken pox with works cited Chickenpox is a highly contagious disease that is caused by a herpesvirus called varicella-zoster virus (7). Chickenpox is one of the most easily transmitted of contagious diseases (5). Ninety to ninety-five percent of the people exposed to the virus will develop it within twenty-one days (5). The term chickenpox came from chickpea, which is a member of the bean family and resembles the look of the swollen pox, or from the Old English gican, meaning �to itch...
Chicken pox
Chicken pox Everybody knows what the chicken pox are, they are when you get bumps all over your body. The cause of the chicken pox is the virus varicella. Males and females are both able to get the virus, but children ages five to six are the most likely to be infected.Like I said chicken pox is caused by the virus varicella. Chicken pox is very contagious and unless you got it at birth one attack carries lifelong immunity. The chain infection is only present if a group of peop...
Chemical warfare
Chemical warfare Chemical warfare is war fought with chemicals. The development of chemical weapons and defenses against these weapons are usually considered together in military training. These weapons can be designed to kill large numbers of people, disable them for a while, or destroy their food supplies. The weapons are usually effective without destroying property. Chemical agents affect the nervous system, breathing centers, skin, eyes, nose, or throat. They include gases, liquids, ...
Chemistry hits the beach
Chemistry hits the beach In our society it's a given that suntans look attractive, and it's also understoud that they can be harmful, and downright unhealthy. So what does this mean? This means that there is a multi-million dollar a year industry that researches and manufactures UV absorbing and blocking lotions that are designed to prevent skin damage from tanning and burning. It is a prime example of the use of chemistry to improve the quality of life for many people, writes Wyn Locke.1 ...
Chemistry investigation
Chemistry investigation Investigate A Factor Which Affects the Rate Of Fermentation Of Yeast This experiment is investigating one of the factors which affects the rate of fermentation of yeast. Several factors affect the rate of reaction: Increasing the concentration. (See the lock and key theory.) If the substrate (glucose) is increased, then there would be more keys for the locks, therefore an increase in reactant concentration leads to an increase in react...
Chemistry soaps and detergents
Chemistry-soaps and detergents Cleaning with soap and soapless detergents. Detergent comes from the Latin word detergere meaning to clean, it is defined as a cleansing agent. Therefore, water itself is a detergent. This essay looks at soap and soapless (or synthetic) detergents. Both substances we use everyday and have a big market commercially, they effect everyone. Soaps are made from natural products and soapless detergents are produced chemically, each havin...
Chemistry
Chemistry Robert Boyle is considered both the founder of modern chemistry and the greatest English scientist to live during the first thirty years of the existence of the Royal Society. He was not only a chemist and a physicist as we know him to be, but also an avid theologian, a philanthropist, an essayist, and a beginner in medicine. Born in Lismore, Ireland to Richard Boyle, first earl of Cork, and Katherine Fenton, his second wife, Boyle was the youngest son ...
Charles darwin and richard owen
Charles darwin and richard owen Charles Darwin and Richard Owen Wars occur everyday, whether it be pushing and shoving or shooting and bombing. During the 1800's, a different war of conflict took place. This so-called war between Charles Darwin and Richard Owen circled on the topic of evolution. As much as it would liked to have this essay based upon a physical war between these two opposing figures, it is not the case. This war involved the use of text written by Darwin and me...
Cheetah 2
Cheetah 2 Cheetah (Acinonyx Jubatus) I chose to do my television project on the cheetah which I saw on the Discovery Channel. Although I knew some interesting characteristics on the cheetah, I did happen to discover some facts I did not know. Those of which are written in the rest of the paper along with some facts I thought were pretty cool. The cheetah is an endangered species and has been for quit some time. This is mainly due to poachers who hunt and kill this animal f...
Cheetah
Cheetah The Cheetah I'm going to talk to you about the Cheetah, Where it lives, how it hunts, how the grass helps the cheetah, mating, and what you can do to help the endangered species. The Cheetah (Acinonyx Jubatus) is the fastest land mammal on earth, capable of speeds of 60-70 miles per hour. Cheetahs live 12 years (17 in captivity) and mature at 20-23 months of age. They are highly territorial. A typical adult cheetah weighs between 80 and 140 pounds and eats about 6 pounds ...
Chemical bonding
Chemical bonding Chemical bonds are what make up the world. In bonds, elements are held together and form compounds that may have new physical and chemical properties. There are two main kinds of bonds, they ionic and covalent. In bonding the goal of the atoms involved is to reach a level of stability with less energy. In order to reach the epitome of stability, as in the case of noble gases, an atom strives to complete its outer shell. Either losing or gaining electrons may do this, whi...
Cetaceans and evolution
Cetaceans and evolution Cetaceans There are many forms of cetacean life living in the worlds waters. How an why they came into existence is uncertain, but there have been many theories. Some say that dolphins are aquatic forms of goats, and others believe they evolved just like everything else, from a single cell, and not from an actual multi-cellular being. Because most cetaceans have some vestigial structures such as under-developed os coxae, the former of these two theories re...
