Road Salt And The Environment
1,465 wordsAs awareness for pollution increases, other less noticed types of pollution are recognized. Almost everyone knows about toxic waste and carbon dioxide pollution, but not many people have heard of salt pollution. Salt pollution has been on the increase since the evolution of the automobile. With more pressure on government agencies to keep the highway clear and safe, an increase in the use of salt has developed. It is important to understand why salt is used and how it work as well as the environ...

Biology Lab Report Genetic Exchange In Prokaryotes
679 wordsThis lab deals with the process of genetic exchange in prokaryotes. There are three main mechanisms of genetic exchange which include transformation, transduction, and conjugation. In transformation, DNA is released from cells in the surrounding environment which is then incorporated into the recipient cells DNA. In transduction, DNA is transferred through a virus to the recipient. In conjugation, genetic exchange occurs through direct contact with another cell and the plasmid is transferred fro...

Cystic Fibrosis Genetic Engineering
1,074 wordsGenetic Engineering is the alteration of genetic material by intervention in genetic processes. Geneticists, the scientists that specialize in gene therapy, are working very diligently to map out the suspected 100, 000 to 150, 000 genes that make up the human body. They plan to have it complete by 2005 (Boukhari 1). With this map of the charted genes Jeff Kunerth, writer for the Orlando Sentinel says, It is one of the many scientific advances that literally will redefine life in the next millenn...

Birth Control Pills Benign Tumors
2,111 wordsWhat is Cancer? Cancer is a group of many related diseases. All forms of cancer cause cells in the body to change and grow in an abnormal way. Normal body cells divide and grow in an orderly fashion. But cells changed by cancer can divide and grow out of control. This out-of-control-growth damages normal body tissues and disrupts the ability of organs to function, as they should. During the early years of a persons life, normal cells divide rapidly until adult size is reached. After that, normal...
