My research was mostly conducted over the internet but by using newspaper articles on the subject of discussion or magazine articles that are online. I decided to look at dieting and obesity for my research task. I first thought about whether or not I thought dieting was good for a person and decided that it wasn’t good for people. Then I started to research more and found that what I believed was right. Dieting isn’t good for a person because once you lose weight; you put it back on when you stop

You may often get told to wear sunglasses to protect your eyes‚ but you may not know what can happen if you don’t wear them. Many people don’t realize how much damage the sun’s harsh rays really can do to their eyes‚ and sun damage to your eyes can show up immediately and later in life. Next time you plan to leave the house on a sunny day without your sunglasses‚ remember these ways you will be harming your eyes if you skip them. 1. You Can Get Sunburn on Your Corneas Now If someone told you that

Abstract This experiment investigated the kinetics of the enzyme glycogen phosphorylase b which is important to metabolism. AMP is an allosteric activator of the enzyme because it converts glycogen phosphorylase b from its T state to the R state which is the active form. Caffeine is an inhibitor because it binds the nucleoside inhibitor site. When it binds this site‚ it stabilizes the inactive T state and blocks the catalytic site which needs to be open for enzyme activity to occur. The glycogen

Advertisements clearly play a huge role in society today; it seems as if there is a promotion for a new product around every corner. Advertising is how many companies are able to sustain their businesses and to gain more profits. However‚ some have criticized advertisements for their influence on people. While advertisements can draw in new customers‚ they can also cause people to be less mindful about what they are actually buying. Sometimes advertisements can even be misleading‚ which is a cause

During‚ the period of the eighteenth century to the nineteenth century the Europeans held a strong belief in scientific proof. The belief in scientific proof is associated to the Age of Enlightenment‚ a period in Europe in which people thought their beliefs should depend on reason and scientific proof. This period is referred to a time when people “set out by means of reason and direct observation to discover the fundamental laws governing nature‚ humanity‚ and society. The Enlightenment Philosophers

In this quote‚ Mathabane describes his struggle to find meaning in school during the apartheid through his father’s comments about education. Mathabane uses parallel structure to demonstrate the contrast between his father’s view of the value of an educated man and the value of an uneducated man. His father‚ having grown up in an impoverished tribal reserve‚ is unable to understand the use of an education to his son’s wellbeing. He uses the word “books” (151)‚ as metonymy to represent education as

Grignard Synthesis of Tirphenylmethanol David Szuminsky Organic Chemistry Lab II Shaopeng Zhang Monday 1PM 2/10/14 & 2/24/14 - Abstract A sample of triphenylmethanol was prepared using Grignard synthesis techniques. Reflux was used in order to speed up the reaction and the final product was purified using recrystallization methods. The percent recovery and percent yield were 80.46% and 47.526%‚ respectively. A melting point range of 85-87oC was obtained from

One of the most known theories is the Activation Synthesis Theory. J. Allan Hobson developed this theory in the late 1970s after running an experimental study on cats focusing on rapid eye movement sleep (REM) (Domhoff‚ 2003). The Activation Synthesis Theory simply states that our cerebral cortex is trying to interpret random electrical activity we have while sleeping. Hobson argued and quoted that

follows a semi microscale technique even a small amount of lost product yields a great loss in the yield 4. These sources of error could be minimized by doing a larger reflux in order to increase the yield. However‚ as the purpose was to simply synthesis SnI4 in order to identify the stable oxidation states (the melting point range requires very little product) it would be advantageous to use the current method. This is due to the smaller quantity of materials needed for this type of reflux‚ thus

Introduction: Acetaminophen is a commonly used analgesic‚ which is essentially just a medicine that relieves pain (Prescott‚ 2000). Acetaminophen is created by synthesizing p-Aminophenol with Acetic anhydride. This reaction occurs when the amine group of the p-aminophenol is acetylated by the acetic anhydride. The resultant is an amide functional group (Ellis‚ 2002). However‚ the product that is obtained from this product is a crude solid which cannot be used as an analgesic and therefore the crude
