... of genetic mutation and a new understanding of genes and DNA, the evidence supporting evolution has greatly increased. Charles Darwin was one scientist who helped to increase the evidence supporting evolution. Darwin developed the idea of “natural selection” where living things that reproduced in large numbers and survived became dominant and other living things adapted to survive, or they died. Francis Crick, a scientist, co-discovered DNA which opened new doors to the idea of evolutionism (History). DNA is the pattern by which people are created as individuals. Now Evolutionism is the only origin of life that can be taught in public schools. ...

... x-ray and computer system that makes detailed pictures of horizontal cross-sections of the body, or the part of the body that is x-rayed. A CT scan is a diagnostic test that combines the use of x-ray with computer technology. A series of x-beams from many different angles are used to get these cross-sectional images of the patient’s body. In a computer, these pictures are assembled into a 3-dimentianal picture that can display organs, tissues, bones, and any such thing. It can even show ducts, blood vessels and tumors. One of the advantages of CT is that it clearly shows soft tissue structures (such as brain), as well as dense tissue structure (such as bone). ...

... petroleum products. The unfortunate and unavoidable by-product of these manufacturing processes is dioxin, one of the most toxic substances on the planet earth. Dioxins are also produced whenever chlorine containing substances, such as PVC, are burned. Life as we know it will change, if a Greenpeace campaign is successful. The powerful environmental group has mounted a well-organized campaign that has as its objective nothing less than a total, worldwide ban on chlorine. With the public health and billions of dollars at stake, the debate over chlorine has become one of the world's most contentious and controversial issues. "Is a chlorine-free future ...

... Celsius, and it's boiling point is 3000 degrees Celsius. It burns in oxygen forming ferrous oxide. When exposed to moist air, iron becomes corroded, forming a reddish - brown, flaky, hydrated ferric oxide, commonly known as rust. (Encarta, 1996) Iron is formed in shallow seas. It comes out of the water and collects on the sea floor. This creates an underwater deposit. This process occurs over billions of years. Through plate movement the whole sea floor is eventually moved up out of the water. Once out of the water, the iron has formed a land deposit. The biggest iron deposit in the United States is in the Great Lakes. Northern Minnesota is often called ...

Everyone, at some point, has experienced the feelings that Wright describes. And with the pronoun ‘we' Wright tells his readers, ‘Yes, I have been through the same things.' This sort of statement is like a token of good will. The readers feel that Wright understands their plight and thus are more likely to listen to what he has to say. With this trust established, Wright moves on to the task of building confiden ...

... algae, fungi, bacteria, viruses, and rickettsiae. A microbiologist is a scientist who studies life forms that can only be observed by means of a microscope. Microbiologists use many criteria to classify bacteria. The Beginning of Microbiology Zacharias Jansen created the microscope. Although Robert Hooke is the one who made it widely known. In 1665 Hooke published a book called Micrographie. It contained his thoughts on chemistry as well as a description and list of uses for a microscope. With this he opened the door to microbiology. For the first time the world was able to see very small creatures and objects. From the use of a microscope he was able ...

Some of these substance are paint, glues, white out, air conditioning refrigerant, felt tip makers, spray paint, air freshener, butane and even cooking spray. Inhalants can really harm the body. Almost all inhalants can cause the body to slow down. The user can suffer Sudden Sniffing Death Syndrome this means that the user can die the first time he or she uses an inhalant. Inherits can effect the other part of the body like the heart, liver, kidney, brain, bone marrow and many other organs. Inhalants can cause some of the same problems in pregnancy as alcohol does. There is link between inhalant users and prob ...

... and Alpha are different terms used to describe the brain waves given off during these states. When the subconscious (subcon) or “Alpha” mind is responding, different commands, or suggestions, can be implemented into the mind. The subcon mind can then execute these imbedded commands without any intervening of the conscious mind and body (Hunter). Hypnosis was first confirmed to be real by a Swedish therapist named Anton Mesmer around 1775. After publishing papers describing the Alpha Mind State, he named the entire process “Mesmerism”. When a person was hypnotized, they were considered “Mesmerized” (Hyde 84). He would mesmerize ...

... similar to how gasoline cars work, with the alternator using the engine's power to recharge the battery. After the power supply is replenished the gasoline engine shuts down. Also the gasoline engine is used to power the vehicle as it reaches the higher speeds where the added horsepower is needed. Usually the speed at which the gasoline engine starts is in the 30 mile per hour range. Even as the gasoline engine runs the electric motor continues to provide power for the vehicle. This vehicle combination in my opinion is beneficial economically and environmentally. There are many benefits for the hybrid vehicle. The price of hybrid cars present day is near seventeen ...

... the waste product carbon dioxide. As a result of these reactions, each pyruvic acid molecule is transformed into a two-carbon compound called an acetyl group. The two acetyl groups combine with a molecule of coenzyme A each to form two acetyl coenzyme A molecules. These molecules are processed in a complex pathway called the Krebs cycle. As the Krebs cycle progresses through both pyruvic acid molecules, six molecules of NADH, two molecules of ATP, and additional carbon dioxide are all formed. FAD picks up a hydrogen atom from each pyruvic acid molecule, and a total of 2 FAD2 are formed. NADH and FAD2 transport their hydrogen atoms and electrons to the elec ...
