The Tower of Babel and the Nimrod Effect - The Tower of Babel and the Nimrod Effect The Tower of Babel and the Nimrod Effect which ensued are powerful reminders of the sovereignty of God. All too often, however, man's innate desire to be recognized as a god gives rise to a despot; a ruler who condones and advocates the dehumanization and enslavement of mankind. This common occurrence is referred to as the Nimrod Effect, with the ruler titled an Oriental Despot.

The Effect of Interferon on Infection and Disease - The Effect of Interferon on Infection and Disease Interferon is a natural occurring substance produced by the body in response to infection and disease. It is a protein belonging to the cytokines family and they are a form of chemical messengers that send signals from one cell to another. Manufactured forms of interferon have been shown to help the body's immune system fight off disease more effectively. The interferons we use are made with recombinant DNA techniques. This means that we put the genes for interferons into bacteria so that they now have the ability to make them....   [tags: Papers] 515 words

The Effect of Temperature on the Rate of Reaction - The Effect of Temperature on the Rate of Reaction Plan: We must produce a piece of coursework investigating the rates of reaction, and the effect different changes have on them. The rate of reaction is the rate of loss of a reactant or the rate of formation of a product during a chemical reaction. It is measured by dividing 1 by the time taken for the reaction to take place. There are five factors which affect the rate of a reaction, according to the collision theory of reacting particles: temperature, concentration (of solution), pressure (in gases), surface are (of solid reactants), and catalysts....   [tags: Papers] 970 words

In this case I am going to look at hydrochloric acid and sodium thiosulphate which is a precipitation reaction causing the solution to go 'cloudy'. They react as in the equations below: sodium thiosulphate + hydrochloric acid -> sodium chloride + sulphur + sulphur dioxide + water Na2S2O3(aq) + 2HCl(aq) -> 2NaCl(aq) + S(s) + SO2(g) + H2O(l) A reaction will only occur where the particles of the reactants meet and combine....   [tags: GCSE Chemistry Coursework Investigation] 2593 words

The Effect of Temperature on the Rate of Reaction - The effect of temperature on rates of reaction Aim: The aim of this experiment is to find out if the reaction rate of sodium thiosulphate solution and hydrochloric acid will be affected by a temperature change. Prediction: I predict that as a result of increasing the temperature of the sodium thiosulphate, the rate of reaction will be faster. Because of the increase in temperature, the particles will gain more kinetic energy. This will therefore cause them to move faster and produce more successful collisions, causing the rate to increase....   [tags: GCSE Chemistry Coursework Investigation] 1230 words

The Cause and Effect of HIV in Africa - The Cause and Effect of HIV in Africa The ubiquitous acronym HIV stands for Human Immunodeficiency Virus. It is a virus that gradually weakens the immune system until the body cannot fight off common infinitesimal infections such as pneumonia, diarrhea, the “flu”, and other illnesses. All of which can be part of the Acquired Immunodeficiency Syndrome, the final stage of HIV that usually develops between 2 to 10 years after the infection. This infection is frequently transmitted through unprotected intercourse with someone who has already been affected with HIV and is an increasing problem in Africa....   [tags: Biology Medical Biomedical Disease HIV AIDS]

The Effect of Underwater Acoustics on Whales - The Effect of Underwater Acoustics on Whales Whales utilize acoustic frequencies to communicate underwater. If the whales are unable to communicate their bi-annual migration can become perilous. Man-made low frequency sonarcan prevent whales from producing soundand sometimes causes them to take alternate routes. When the whales try to avoid the sonar they are in danger of running ashore and perishing after being beached.

The Effect of pH on Enzyme Activity - The Effect of pH on Enzyme Activity pH is a measure of the concentration of hydrogen ions in a solution. The higher the hydrogen ion concentration, the lower the pH. Most enzymes function efficiently over a narrow pH range. A change in pH above or below this range reduces the rate of enzyme reaction considerably. Changes in pH lead to the breaking of the ionic bonds that hold the tertiary structure of the enzyme in place. The enzyme begins to lose its functional shape, particularly the shape of the active site, such that the substrate will no longer fit into it, the enzyme is said to be denatured....   [tags: Papers] 602 words

The Effect of Temperature on Yeast Respiration - The Effect of Temperature on Yeast Respiration PLAN Aim: To determine the effect of temperature upon respiration of Yeast. Prediction: I predict that the respiratory rate of the yeast will increase in speed as the temperature of the water increases. However, it may reach a peak, and slowly decline as the temperature increases further. My reason for the above prediction is that, anyone who has cooked, knows that yeast is supposed to respond in warm water, so I believe that the warmer the water, the more bubbles of CO² produced....   [tags: Papers] 1406 words

Cause and Effect of the Fitness Movement - Cause and Effect of the Fitness Movement In our ever-changing society, the one common thread that now every American seems to possess is a desire to have a body that is not hour-glass (1950’s) nor waifish (1990’s), but one that is lean, trim, and can physically go the “extra mile”. I speculate that the all-around athletic look is so popular because it is probably one of the hardest body types to achieve.

The Simon Effect: A Case Study - Introduction: The Simon effect refers to the finding that people are faster and more accurate responding to stimuli that occur in the same relative location as the response, even though the location information is irrelevant to the actual task (Simon, 1969). In studying the Simon effect it is possible to understand response selection. There are three stages which must be taken into consideration: Stimulus identification, response selection and response execution. Thus, the focus of this experiment is to determine whether or not people are faster and perhaps more accurate responding to stimuli in the same relative location as the response, despite the fact that the location information...   [tags: essays research papers] 835 words
