For the last few decades, cloning was a fictitious idea that lay deep within the pages of some sci-fi novels. The very idea that cloning could one day become reality was thought to be a scientific impossibility by many experts but on one exhilarating day, what was thought to be "purely fiction" became reality. That fine day was February 22, 1997. A team from the Roslin Institute which was lead by Dr. Ian Wilmut changed the face of history forever by revealing what looked like an average shee

In the world's oceans, the surface currents move the oceans' surface water. This occurs in the Atlantic, Pacific and Indian Oceans. From a diagram of these surface currents, a number of conclusions can be made about the general patterns of the surface currents. One of these conclusions includes that they go clockwise in the Northern Hemisphere and counter-clockwise in the Southern Hemisphere. The Northern Pacific circulation goes around in a clockwise rotation. The same thing happens in the Nort

1/29/99 Biology 2 Period 2 Charles Darwin The "un"Scientific Theory of Evolution and the Manufactured Evidenced used Drunken Scientists to Support this Exaggerated Theory. Preface: Teaching the Theory of Evolution is like teaching the Bible in a public school. It's biased and unsupported and is banned by the constitution. I attended Catholic schools for four years. I was subsequently expelled. That experience has left me with the open-mindedness to proceed with t

Atavism According to WebsterOs dictionary atavism, from the Latin atavus meaning ancestor, is OA reoccurrence in an organism or in any of its parts a form typical of ancestry more remote then the parents usually due to genetic recombinations. A throwback.O This means that a person with an atavistic trait, or an atavistic deformity, exhibits a trait that was commonly found in our ancestors but that has been suppressed in the modern generation. Atavism reminds us that the genetic informati

Down Syndrome Down Syndrome is caused by a trisomy of the 21st chromosome, which means that there are three of chromosome 21 instead of 2. Symptoms of the disorder include: mental retardation, abnormal creases in the palm, a flat face, sparse and strait hair and short stature. People with Down syndrome are also at a high risk for cardiac anomalies, leukemia, cataracts and digestive blockage. Fifty percent of babies with the syndrome die before age one. Down syndrome can be detected by

Could an exploding star have been responsible for the death of the dinosaurs? This idea has become popular again as an explanation for the disappearance of the dinosaurs. An exploding star can blast material enormous distances into space. If this material reached Earth's atmosphere, changes may have occurred that were harmful to life. We call an exploding star a supernova. Nova is the Latin word for new, and in ancient times, when an exploding star was observed, people often thought a ne

This is my report about the discovery of the structure of deoxyribose nucleic acid (DNA) as told by James Watson. Watson and another scientist named Francis Crick discovered the structure of this hereditary molecule. These two scientists discovered that DNA was much more important than originally thought by most of the scientists. Watson and Crick used the findings of other scientists with their pursuit to become famous before someone else found the answer. James Watson was an Ameri

For years scientists have been studying evolution and common decent. From Darwin to the modern day scientists humans have been trying to find out about how the world has evolved. Even with modern day technology scientists have trouble finding out how evolution works. Common descent can be proved in multiple ways. Scientists use fossils, embryology, comparative anatomy, biogeography, and biochemistry to give evidence that common descent has occurred. One of the most obvious ways to study e

Bicarbonate: A good buffer for blood Most carbon dioxide generated during metabolism is transported in the form of bicarbonate ions, which result from the dissociation of carbonic acid formed in the red blood cells from the chemical union of carbon dioxide and water. Hydrogen ions from the dissociation are bound to hemoglobin and other proteins, serving to buffer the blood. The entire process is reversed when blood enters the lungs, allowing free carbon dioxide to diffuse into the environment
