This depresses mental, motor, and vital functions such as pulse rate, respiration, and blood pressure (Kestler 6). The body can absorb alcohol very quickly, approximately 20% goes directly into the blood stream from the stomach, the rest enters the body through the small intestine. Moments after alcohol enters the blood stream it reaches the Cerebral Cortex, the part of the brain responsible for judgement. The areas of the brain cont .....

.... and will continue to leave devastating effects on the environment around them. Firstly, to understand the thesis people must know what dams are. A dam is a barrier built across a water course to hold back or control water flow. Dams are classified as either storage, diversion or detention.

The water is then used when there is a lack of supply. For example many small dams impound water in the spring, for use in the summer dry months. Storage dams also supply a water supply, or an improved habitat for fi .....


Genetic Cloning
Words: 1303 / Pages: 5

.... Edinburg, Scotland(Staples). It was a sheep by the name of Dolly. Dolly was cloned from an adult sheep; using donor DNA and mammary cells from a female sheep cloned it. The process is very technical and I don’t fully understand it myself. From what I have researched I have come to understand that currently cloning is very “Hit or Miss”(Hawley). From 277 attempts, Dolly was the only successful attempt. The point is however that we now have a man created sheep, what else could be done in the near future. There are many different goals for .

.... area. “In the 1980's and early 90's this research was banned by both the Ronald Reagan and Bush administrations due to pressure from the pro-life factions of the Republican party.” The societal issue addressed is expressed from all point of views, and the following will further strengthen and help you understand their points. “The procedures used in human embryo cloning have been around for many years, and have been used in the cloning of cattle and sheep embryos, for the production of animals with known genetic traits. The news of human embryo cloning did not surprise many people in the scientific community, but it shocked the ge .....


Bioluminescence In Fungi
Words: 2045 / Pages: 8

.... little heat radiation. This aspect of bioluminescence especially interested early scientists who explored it. The light is the result of a biochemical reaction in which the oxidation of a compound called "Luciferin" and the reaction was catalyzed by an enzyme called "Luciferase". The light generated by this biochemical reaction has been utilized by scientists as a bioindicator for Tuberculosis as well as heavy metals. On going research involving bioluminescence is currently underway in the areas of evolution, ecology, histology, physiology, biochemistry, and biomedical applications. History of Bioluminescent Fungi The light of luminous wood .....


The Evils Of Hunting
Words: 430 / Pages: 2

.... the privilege, after the proprietor of the land has had one negative experience with some other hunter. This can make hunting a much harder sport to participate in, even for the people who are hunting for their livelihood. (Satchell 30) Over the years, hunting has reduced the animal population drastically. In the 1970's, the number of ducks making annual flights was approximately 91.5 million. In 1995, the number had been reduced to around 64 million. Within 20 years, in short, the duck population was reduced by almost one third, showing the drastic toll hunting is taking on our wildlife. If we assume that other species have been reduced in numbe .....

It was primarily used among ancient people for special ceremonies, magic, and medicine, and “by about 1500 BC, Egyptian doctors included beer or wine in about 15 percent of their medicines”(Monroe 8-9). Alcoholic beverages are produced through a process called fermentation using plants such as corn, rye, barley, potatoes, and grapes, and are classified by their typ .....


Nuclear Fission

.... atoms. The split of each atom will produce two more neutrons. The more atoms that are split the more neutrons produced that will split more atoms. As this process is repeated over, it becomes a self-sustaining chain reaction. This energy producing process is called a chain reaction. uses the uranium-235 element because it is the easiest of all atoms to split apart. Uranium-235 is made up of many protons and few neutrons. Protons naturally repel one another so a nucleus made up of many protons tends to ‘fly apart’ more easily. In addition, uranium makes a good nuclear reactor because it can sustain a series of fission reactions, each time .....
