  • Iodine - 721 words
    Iodine Iodine is an essential macromineral. Almost half the iodine is found in the thyroid gland which is located in the throat. Iodine is an important component of thyroid hormones, which control energy, metabolism in the body as well as the bodys temperature, reproduction, and growth. It is not found in the body so it is very important that you get about .15 mg. daily. Some foods such as vegetables, grains, table salt, dairy products, and especially seafood are the best sources of iodine. Breathing in sea air everyday will give you a sufficient amount of iodine to prevent a disease called goiter. There are two types of goiter: toxic and simple. Toxic goiter is caused by excess of thyroxin ...

  • Abortion: Freedom Of Choice - 349 words
    Abortion: Freedom Of Choice Freedom Of Choice Peter Farmer Period 6 Since 1973 abortion has been an important, controversial issue to the United States. The problem should it be a woman's choice whether or not to terminate her pregnancy or should it be the governments choice? This is where a woman looses her rights as a person. If abortion is not remained legal women will start performing them illegally. One half of all pregnancies in the United States end in abortion, 2,500 of these abortions will be performed illegally. Although some oppose abortion for being used as a form of birth control, Abortion should remain legal because it is a woman's choice and protects the privacy of an individu ...

    ... e of Hermetic theory and the consciousness in the alchemical mind that what might with success be applied to nature could also be applied to man with similar results. Says Mr. Waite, "The gold of the philosopher is not a metal, on the other hand, man is a being who possesses within himself the seeds of a perfection which he has never realized, and that he therefore corresponds to those metals which the Hermetic theory supposes to be capable of developing the latent possibilities in the subject man." At the same time, it must be admitted that the cryptic character of alchemical language was probably occasioned by a fear on the part of the alchemical mystic that he might lay himself open t ...

  • Amylase - 309 words
    Amylase The enzyme amylase will catalyze the hydrolysis of starch to maltose when the pH is near 7.0. But when the HCl is added to the solution the amylase will be denatured which results in the enzyme being deactivated. The iodine serves as an indicator for the presence of starch. Iodine (I2) will reach with iodide ion to produce the I3- ion. This ion will form a dark blue complex with the starch molecule. Like most chemical reactions, the rate of an enzyme-catalyzed reaction increases as the temperature is raised. A ten degree Centigrade rise in temperature will increase the activity of most enzymes by 50 to 100%. Variations in reaction temperature as small as 1 or 2 degrees may introduce ...

  • Bovine Tmb - 1,501 words
    Bovine TMB Bovine Tuberculosis Mycobacterium bovis (Bovine Tuberculosis) (or cattle Tuberculosis) was first discovered by Columella (Louis Junius Moderatus Columella) which was born in Cadiz, Spain and resided in Northern Italy when he discovered the bovine Tuberculosis in the year 14 A D. In 1882 Robert Koch discovered that the connection between human and animal Tuberculosis actually were established. When Koch realized that children were becoming infected from contaminated cows milk most nations brought out legal instruments designed to remove chronically infected animals and take a look at the public health aspect of the problem. The Disease Mycobacterium bovis is the bacterium that caus ...

  • Carbohydrates - 1,547 words
    Carbohydrates INTRODUCTION A theme that we have seen and studied in this class is that a particular form or structure of a molecule plays a significant role in the function of that molecule. Since we are interested in the function of molecules. it helps to study their structure. One of the major classes of organic compounds found in cells are carbohydrates. These carbohydrate are made of carbon, hydrogen, and oxygen in a ratio of 1:2:1 respectively with a general formula of X(CH2O)n. When the carbohydrates consists of one unit of sugar, X=1, it is called monosaccharide. If it consists of 2 units, X=2, the carbohydrate is called disaccharide. Carbohydrates made up of more than two units, X>2, ...

  • Chemical Equilibria - 1,497 words
    Chemical Equilibria Darryl Fagan Pd. 4 01-20-00 AP Chemistry An Activity Series Chemistry Lab 5 Introduction; In this experiment you will study some metals and some nonmetals to find their relative reactivity. A ranking according to reactivity is called an activity series. For example, an activity series containing the elements calcium, gold and iron would put the reactive calcium at the top, iron in the middle, and the unreactive gold at the bottom. If a piece of iron metal is placed in a solution of gold nitrate, the iron will dissolve forming positive ions while the solid gold metal appears. The more reactive metal will displace ions of the less reactive metal from solution. The less reac ...

  • Fingerprints - 246 words
    Fingerprints Fingerprints are one of the most important things that link a suspect with a crime scene. Even though that fingerprints are not always left by a criminal, the crime scene should still be examined for them. All people have distinct friction ridges on the skin of the fingers. In leaving an impression, an outline of the ridges is transferred and duplicated by oil, sweat and other substances on the object handled. The impression is usually not visible. Fingerprints not visible are called latent prints; so something must be done to make them visible. The most common way to make them visible is to "dust" an object with fingerprint powder. The color of the powder should contrast with t ...

  • Hormones - 1,052 words
    Hormones IntroductionHormones are organic substances that are secreted by plants and animals and that function in the regulation of physiological activities and in maintaining homeostasis. They carry out their functions by evoking responses from specific organs or tissues that are adapted to react to minute quantities of them. The classical view of hormones is that they are transmitted to their targets in the bloodstream after discharge from the glands that secrete them. This mode of discharge (directly into the bloodstream) is called endocrine secretion. The meaning of the term hormone has been extended beyond the original definition of a blood-borne secretion, however, to include similar r ...

  • Laser Technology - 761 words
    Laser Technology Laser Technology The laser is a device that a beam of light that is both scientifically and practically of great use because it is coherent light. The beam is produced by a process known as stimulated emission, and the word "laser" is an acronym for the phrase "light amplification by stimulated emission of radiation." Light is just like radio waves in the way that it can also carry information. The information is encoded in the beam as variations in the frequency or shape of the light wave. The good part is that since light waves have much higher frequencies they can also hold much more information. Not only is the particle the smallest light unit but it is a particle as wel ...

  • Manganese - 243 words
    Manganese Hi, I am Manganese. I am an element discovered in 1774 by the Swedish chemist Johan Gottlieb Gahn. My symbol was devised, coincidentally, by taking the first and third letters in the word manganese. My atomic number is 25, my atomic mass is 54.938, and my density is 7.2. I melt at 1245 C and then in turn I boil at 1962 C. A fact about my ionization energy currently escapes me, but I do have some uses and interesting facts in the rest of the paper. I am used as an antioxidant nutrient, I activate important enzymes that are needed in digestion, and I am the 12th most abundant element in the earths crust. And now I will switch into a third person perspective because I am bored of talk ...

    Memoirs of a Mountain High It was the summer of 94 when I took a Wilderness Leadership Semester from the Colorado Outward Bound School . Needless to say that it was the most emotional, challenging, and rewarding experience that I have had in all of my 19 ears of existence. One week spent running the Upper Green River in westernColorado and northern Utah. Through The Gates of the Ladour Canyon and Dinosaur National Monument, we floated to end where the Green meets the Colorado River just beyond Echo Canyon. The high desert canyons echoed with rapids ovarious classes; Hells Half Mile and Disaster Falls were the most memorable. Upon completion we headed to climbing camp in Wyoming at a place ca ...

    ... its manufacturing capabilities. (KBI, 1997, p.22) When a methamphetamine laboratory is seized, hazardous waste materials, such as chemicals and contaminated glassware and equipment, must be disposed of properly. Many of these materials are reactive, explosive, flammable, corrosive, and toxic. The danger is compounded by the fact that many federal, state, and local law enforcement officers lack adequate training in clandestine laboratory safety procedures and regulations, hazards, and other related health and safety issues. (University of Kansas, 1995, p.2) Although the quantities of hazardous materials found at a typical methamphetamine laboratory are relatively small when compared to w ...

  • Michael Faraday - 1,928 words
    Michael Faraday It is not my intention to lay before you a life of Faraday in the ordinary accepting of the term. The duty I have to perform is to give you some notion of what he has done in the world; dwelling incidentally on the spirit in which his work was executed, and introducing such personal traits as may be necessary to the completion of your picture of the philosopher, though by no means adequate to give you a complete idea of the man. Michael Faraday was born at Newington Butts, on September 22, 1791, and he died at Hampton Court, on August 25, 1867. When thirteen years old, that is to say in 1804, Faraday was apprenticed to a bookseller and bookbinder where he spent eight years of ...

    Mitosis Cell Lab I Mitosis Cell Lab II. Introduction Life exists almost every where on this planet and if we are to attempt to comprehend what life is in all of its magnificence we must look at its simplest forms. Even a cell, the smallest form of life known is extremely complex. All life begins as a single cell. I can not begin to understand the depth of what it takes for one cell to multiply and change until we become conscious of ourselves. There are two types of cell division, Meiosis and Mitosis. Meiosis is where a cell splits and becomes four different cells. Mitosis is the process that allows a cell to split into two identical cells. This happens by having all of the DNA replicate bef ...
