Genetics Human Genome Project A genome is defined as the complete collection of an organisms genetic material. The human genome is composed of about 50,000 to 100,000 genes located on 23 pairs of chromosomes in a human cell. It is said that a single human chromosome may contain more than 250 million DNA base pairs, and it is estimated that the entire human genome consists of about 3 bill

Genetics Chapter 13 The Properties of Mixtures: Solutions and Colloids Last chapter we talked about pure substances ¡V liquids and solids. This chapter deals with mixtures, specifically homogeneous mixtures called solutions. A solution is composed of two parts called components: 1. solvent ¡V substance present in larger amount 2. solute ¡V substance being dissolved Other terms you w

Biotechnology Jones 1 The Pros of Biotechnology Biotechnology can be used to help humans. As essayist Cecie Starr and Ralph Taggart write “biotechnology can be used to cure rare diseases.” Biotechnology can be used to help any form of life from plants to animals and even food. For more than three billion years, nature has been conducting uncountable numbers of genetic experiments.

Biotechnology Throughout the industrial age, our society and environment has been completely modified by collecting and transforming massive amounts of inorganic materials. Numerous metals, minerals, and fossil fuels are mined, filtered, dug, and pumped from the earth. They are then burned, hammered, soldered, melted, restructured, and recombined to create the machines, structures

Geology Deformation of Rocks- When rocks are put under directed pressures, they may respond to the applied pressure in several ways: 1. Folding or bending 2. Faulting of fracturing Stress Stress = Force / area Concepts of Force and Stress Force : An action exerted by one body on another Force= mass x acceleration Stress: A force acting upon a surface is referred to as p

Geology Current Events I chose an article from the May 2002 National Geographic Magazine. My article is about arguments surrounding the age of the earth. Due to previous beliefs of the earth’s age and new contrasting discoveries geologists are in conflict over merits of both theories. It was formerly believed that rock samples found on Akilia, a small island off the coast of Greenla

Biotechnology What is biotechnology' Biotechnology is a broad term that is applied to all living organisms. It is used for everything from microorganisms used to ferment beer to the most sophisticated forms of gene therapy. Biotechnology is the use of microorganisms or biological substances to perform industrial or manufacturing processes. (*1) The United States government defines it as

Biotechnology Biotechnology: The Brave New World The reason why I choose biotechnology for a subject to do my paper on is because I have a strong interest in the subject matter. When I was in high school I read a book called “Brave New World,” by Aldous Huxley. It was written in 1931. It was a story about a world controlled by biotechnology. Everyone was a clone and their standin

Bioterrorism JAPAN 1995 NERVE GAS ATTACK TOKYO SUBWAY Sarin is a volatile liquid used as a nerve gas. Its vapor is colorless and odorless. Sarin acts by interfering with a chemical which transmits impulses from one nerve cell to the next. A gas mask provides adequate protection from the vapor, but the liquid form can also be absorbed through the skin. Sarin was originally developed

Giant Squid The documentary of Architeuthis was about trying to learn more about these giant squid and also the journey to find one in its natural habitat. No person has ever documented the living existence of the creature. A few people have found washed up corpses of Architeuthis on shorelines. Never has one been found completely intact. The scientists tried to find out breeding hab

Global Warming Global Warming and The West Nile Virus By: M.L.M. The increase in the population of the world may be affecting us in more ways than previously thought. The usage of fossil fuels increases as the population increases. When a baby is born the immediate need for fossil fuels are increased. One example of this is the immediate need for fuel used to heat the water for th

Global Warming Is the Threat of Global Warming Real' Is the threat of global warming real' Many people believe it isn’t real, however some do. Ross Gelbspan points to a variety of scientific evidences, including a 1995 announcement from 2,500 scientists, indicating that the planet is warming. Brian Tucker, a senior fellow of the Institute for Public Affairs, argues that there are st

Global Warming Just the beginning of a coming calamity’, global warming, the rise in the average surface temperature of the planet, has been a controversial topic for the past several decades. Many scientists have portrayed it as the end of our world, a doomsday, predicting that unnatural increases in greenhouse gases will contribute to drastic temperature increases over the next century

Global Warming Purpose: To persuade people that global warming is a very important issue and we need to take action to prevent its harmful effects. Introduction: Attention Step: In 1995, a major motion picture was released by Hollywood called Waterworld. When we saw this movie believing that earth would be covered in water seemed extremely far-fetched. But this idea is not

Global Warming Global Warming is the rising of the Earth’s surface temperature due to chemicals in the atmosphere. Global Warming has many threats on the climate and even the health of the people on this planet. Some of these threats include the altering of crop seasons and even effect the way organisms survive on the planet. The first thing I think I should discuss when talking about

Global Warming GLOBAL WARMING The main gases that cause the greenhouse effect are water vapor, carbon dioxide (CO2), and methane, which come mainly from animal manure. Other gases like nitrogen oxide and chlorofluorocarbons, man made gases, get caught in the atmosphere as well. The decay of animals and respiration are two main natural sources of carbon dioxide. In my opinion, we the p

Global Warming - Fact Or Fiction Global Warming: Fact or Fiction For many years now, the subject of global warming has been the cause of heated debates throughout the world. The theory is based on the idea that greenhouse gasses are accumulating in Earth’s atmosphere as a result of human activities, causing surface air temperatures and subsurface ocean temperatures to rise. Debates

Birds Attracting Birds to Your Backyard Information supplied by Kaytee Inc. Attracting birds to your yard is fun and easy. It can be as simple as hanging a single feeder in your yard. But if you want to attract more birds and a greater variety of birds, consider the following suggestions: Offer a Variety of Different Foods Different birds like different assortments of seeds.

Gloval Warming The earths climate is predictable to change because human activities are altering the chemical position of the atmosphere through the buildup of greenhouse gases ------ primarily carbon dioxide, methane, and nitrous oxide. These gases have the heat-trapping property. Rising global temperatures are expected to threaten many types of ecosystems. Through the article I picked

Glucophage Polycystic Ovarian Syndrome, or PCOS, is common among five to ten percent of women around child bearing age. It is also the leading cause of infertility in women. Researchers have not yet found a cause for this condition but speculate genetic hereditary as the cause. Some symptoms of PCOS are irregular or absent menstrual periods. The infrequent ovulation in PCOS women produce

God Evolution This short report will give you a short summary on evolution and how it my affect us, or even surroundings. Also, how it my affect our food chain and if one thing would die how the other would suffer because of that, for an example if you had snakes and birds and if snakes were to die birds population would drop. Why, because birds feed on snakes. Now a part of the fo

Birth Control Birth control is used to prevent unwanted pregnancy. Birth control has been a concern for humans for thousands of years. We have come a long way from early forms of contraceptives, although some of the same concepts are still used. However, it is important to note that different kinds of birth control have various effects. Some methods of birth control are more reliable th

Great Lakes Drilling The Risk of Pollution from Drilling under the Great Lakes is to great The Great Lakes contain 20 percent of the world’s freshwater and is home to more than 35 million people. Currently there is a ban against directional drilling under the Great Lakes. Directional drilling enables oil and gas deposits beneath the lakes to be tapped from a distance

Black Holes The universe as we know it is an amazing thing. There is so much we have learned, but there is even more that we have yet to understand. One of the great mysteries of the universe is the black hole. While most people are not really sure of what they are, some think that they are a magical gateway into another galaxy or another part of our universe. The mystery surrounding

Alternative Fuel Petroleum will not be a source of fuel for much longer. What are we going to do when it runs out' I will explain alternative sources for fuel or energy for vehicles that are already in use or that have been proposed. With each source I will discuss the pros and then the cons of it. The first alternative fuel source I will discuss is Biodiesel. Biodiesel a clean bur

Black Holes Black Holes: Infinity and Beyond If theories of their existence are true, black holes are the most powerful force in the known physical universe. Many people are familiar with the term black hole, but few people actually know anything about them. A black hole forms as a result of a massive star running out of fuel to burn (Chaisson, 193). Once the star is no longer ex

Biology Lab Materials and Methods A single Daphnia is placed on a microscope slide with a depression well and covered with one or two drops of water. The Daphnia is then covered with a cover slip and placed under the microscope. Look through the microscope and count the number of heartbeats in one minute using a stopwatch. Record this data on a chart. Then, using the same daphnia

Cloning Vs Nature Cloning: Nature vs. Man There is moral concern and laws against the murder of people. Murderers are of the lowest class of sinners and regrettably pay for their decisions the rest of their life. Just as taking the life of a man is wrong, so is the unnatural creation of man. As some would say the end justifies the mean, it is argued because the unique

Conductivity Of Water Abstract This experiment was designed to explore nature of water as it pertains to conductivity. It can be shown that the conductivity of a substance is directly related to the amount of dissolved salts in the substance, as salts are ions. One contributor to water conductivity, therefore, is soil, as it contains many minerals and other substances which, when diss

Continental Drift Continental Drift And Plate Tectonics The evidence which gave rise to the theory of continental drift -- more correctly called plate tectonics -- includes the following: · The coasts of the continents surrounding the Atlantic Ocean could fit together like a jigsaw puzzle. · Living animals in widely separated lands are similar. · Fossil plants and animals i
