Ethics Of Cloning For nearly a century, cloning has been the subject of popular fiction even though the technology was lacking in reality. Recently, with the successful cloning of Dolly the sheep, many suspect that clones of humans or human parts will soon be realized- if not already. Therefore, it has become increasingly necessary to consider the possible harms to humanity this new sc

Papilloma Virus Human Papilloma virus is one of the most common causes of sexually transmitted disease. This is a type of virus that causes warts on people. There are more than 60 types of HPV found. A few types cause warts on hands and feet. One third of them are spread through sexual contact and live only in genital tissue. Low- risk types causes genital warts, the most observable sign

Other Life Forms' Are there aliens in the kitchen cooking breakfast after waking up in the morning' Or perhaps playing with the dog in the backyard' With the facts from the movie K-PAX and research on the Universe, it is obvious that there is no life out there other than our own. In the movie K-PAX, a man by the name of Prot claims to be from a planet called K-PAX, which he claims is i

Our Ozone The ozone layer is a region of the atmosphere that protects us from the harmful effects of the sun. It works as a filter that lets in UV rays that are vital to the health of the earth; it also blocks harmful rays that are dangerous to humans and the environment. It is formed by the reaction that sunlight has on oxygen. This cycle has been going on for millions of years; the o

Centrifugation Lab INTRODUCTION The purpose of this experiment was to separate and identify the lower density particles in a homogenous mixture. Thus, the objective of the exercise was to realize that there is more than one structure in the cytoplasm and to isolate them using homogenization and differential centrifugation. In doing so, one can recognize and identify these particles

Oysters Oyster An oyster is a shellfish with two rough white shells that connect together at one point. The oyster has very strong muscles that hold the shell shut. It is very hard for predators such as humans to pry the shell open. An eastern oyster is usually two to six inches long. There is a purple mark that is left behind when the oyster is removed from the shell. The purple m

Cerium Cerium Cerium is in the sixth period of the periodic table. It’s atomic number is fifty-eight, which means it has fifty-eight protons and electrons. It has an atomic mass of 140.12, giving it eighty-two neutrons. Cerium is a soft, iron gray metal of the rare earth group of chemical elements, also called the lanthanide series. It’s also a solid. Cerium was discovered in 1803 by

West Nile Virus Aside from contracting the virus through mosquito bites, many people became infected with the disease through blood transfusions (Couzin, 2003). There has been little time to create an adequate test for West Nile in blood samples. Most blood banks test for antibodies in the blood, which show that the person has and is responding to West Nile disease (Couzin, 2003). The

Lobster Lobster A lobster is an invertebrate that has an exoskeleton. This means that they have to molt in order to grow. Molting is where the lobster sheds its external shell. The reason you don’t see theses shells is because a lobster will usually eat the shell to get extra calcium to help harden the new soft shell that has developed. They will usually do this 4-7 times a year by t

PH Fermintation In our experiment with pH, we did three replicates, hoping for accurate readings. By doing, three replicates we found out results had variations. Our hypothesis states if the rate of fermentation is dependent on pH, in acidic pH the reaction will happen at a faster rate. From this statement out hypothesis is partially correct. The acidic pH3 never reacted at a fast ra

Penicillin It is said the “wonder drug” penicillin was first discovered in 1929 by a Scottish doctor and researcher Alexander Fleming, but the writer of source number 8 says, “that based on records dated back to the 1500’s, there were many discoveries leading up to that of Fleming. For instance, in 1874, William Roberts observed that bacterial contamination is generally absent in culture

Peripheral Introduction Peripheral Devices A Peripheral device is any external device attached to a computer. Without Peripherals a computer is just a box full of wires, transistors and circuits, which is able to: - 1. Respond to a specific set of instructions in a well-defined manner. 2. Execute a prerecorded list of instructions (a program). The only problem being that without any in

Biology Loss of habitat, climate change and UV radiation are just a few reasons for earths dramatic drop in amphibian’s population in the recent years. Amphibians have lived on our earth longer then humans and adapt to a wide variety of habitats over the years. A recent study had proved that human neglect and ignorance has greatly impacted the amphibian population. In the

Outer Space Life Life exists on other planets. Out of the billions of solar systems, there has to be a chance that a least a couple planets have the ability to support life. Life may have developed on the planets like life developed here, but it may have developed differently also. Are they more intelligent than we are or are they single-celled organisms' It goes back to how life on Eart

Alumnum Aluminum (8 pages w/ double space size 12 Arial, not including Bib.) Aluminum is one of a number of soft metals that scientists call "poor" metals. It can be shaped and twisted into any form. It can be rolled into thick plates for armored tanks or into thin foil for chewing gum wrappers. It may be drawn into a wire or made into cans. Aluminum is a generally popular metal bec

Human Genome Project The Human Genome Project is a worldwide research effort with the goal of analyzing the structure of human DNA and determining the location of the estimated 100,000 human genes. The DNA of a set of model organisms will be studied to provide the information necessary for understanding the operation of the human genome. The information gathered by the human genome proje

Hunger Pain Over the years, scientists have proposed many hunger signals. Some researchers argued that the contracting stomach provides the trigger. One investigator went so far as to swallow a balloon and inflate it. This dulled his appetite all right, but other researchers countered that people who had had their stomachs surgically removed still became hungry. Biologists have also

Bioengineering Technology “To play or not to play… God'” Since so many scientist don’t believe in God, they are trying to become one. It is now the twenty-first century and scientist have come along way. They have made an enormous leaps and bounds in scientific fields. Scientist has improved the biotechnology of cloning genetic manipulation, and selecting embryos. Cloning is an issue t

Karst Formation Florida Karst Formation: A Geochemistry Profile Abstract Florida is a perfect environment for karst formation. In most parts of the state limestone, CaCO3, and other carbonates constituent a majority of the subsurface rock. This formation is the remnant of ocean sediments uplifted from the ancient sea. There are other reactants in the dissolution equation though. Liqui

Extinction Is The Question In the argument, “Why worry about extinction,” David M. Armstrong says that humans are accelerating the extinction rate, while Norman D. Levine argues that extinction is just the course of nature. Armstrong teaches science for nonscientists at the University of Colorado and has written several books on the mammals and ecology of the rocky mountain region. Levin

Photoperiodism Photoperiodism annon Plants and animals in the temperate zones respond in different ways to the amount of daylight in 24-hour periods. This response to day length is called photo periodism. It controls many activities, among them is the flowering of plants. The ability to respond to day length is linked to an inner, light-sensitive circadian rhythm. In the temperate zo

Physics Of Paper Airplanes Most people believe that a paper airplane is a very basic children’s toy that is cheap as well. But beyond the fun and excitement that is gained from playing with paper airplanes, there is a lot to learn about the physics of the plane. Certain factors determine whether or not a paper airplane, which acts as a glider does, will fly well. Some of these factors

Charles Richard Drew Dr. Charles Richard Drew 1904-1950 The man for whom Charles R. Drew University of Medicine and Science in Los Angeles is named, was a brilliant black physician, famous for his pioneering work in blood preservation. Born in Washington, D.C. on June 3, 1904, his life ended in an automobile accident just two months before his 46th birthday. The intervening years

Darwin And Natural Selection The importance attributed to natural selection as a cause of evolution varies widely. The operations of natural selection, real or imagined, are not accessible to the human eye. Natural selection is usually meant, the belief that random variation can, when subjected to selective pressure for long periods of time, culminate in new forms, and that it therefore

Pig Lab Report Introduction: Animalia is the kingdom that we are most familiar with and includes organisms such as humans, dogs, whales, and reptiles. In this exercise, you will study the anatomy of a fetal pig. Pigs are very similar to humans, and much of the experimental cloning of human organs is being conducted on pigs. To allow for easy identification, veins of the pigs have been

Pesticides When discussing issues of pesticide uses and its impacts on the environment, there are four major contributors involved: Rachel Carson, Robert Van Den Bosch, Sandra Stiengraber, and Theo Colburn et. al. These contributors have covered the issues from trying to control nature with chemical poisons to pesticides causing cancer. Some of these people have lived their entire live

Petroleum- Should America Import Oil' “Petroleum is the most important fossil fuel in the modern industrial world” (Craig, 2001). Petroleum, a base for many types of fuel and lubricants, is nonrenewable resource. One day, we will have no more oil; but until that day comes, earth’s inhabitants will have to buy and sell the petroleum that currently exists. Some Americans say that the

Plate Tectonics Paper #1 Plate Tectonics is a theory proposed and accepted by scientists to explain the nature of earth’s surface characteristics and oceanic and continental makeup. Plate Tectonics divides the earth’s surface into separate sections known as lithospheric plates. These lithospheric plates are composed of the hard rigid outer crust of the earth which “float” on top of t

Platinum Platinum is a relatively rare, chemically inert, metallic element. It symbol is Pt, atomic number is 78, and its atomic weight is 195.09. Platinum is one of the heaviest substances known. One cubic foot of Platinum weighs 21 times as much as a cubic foot of water. A grayish-white metal, Platinum has a melting point of 1772 degrees C and a realatively high boiling point of 38

Automated Fingerprint Identification System AFIS (Automated Fingerprint Identification Systems) allows law enforcement agencies to conduct applicant and suspect fingerprints with literally thousands or millions of file prints in a matter of minutes. A manual search of this nature would take hundreds of hours with little hope for and less chance of success. The heart of AFIS technology
