by the presence of Hydrogen ions‚ our cells cannot function properly. This experiment was conducted to determine if the reaction rate changes in response to a variation of acidic‚ neutral‚ and basic solutions. The experimental results indicated that the basic/high pH solution has a faster rate of reaction in the solution. Introduction Enzymes are proteins that catalyze and convert molecules into combinations of other molecules which is necessary for the functions of human life. These enzymes

Singular words and expressions are the building blocks of fiction. Good writers are constantly caring about their choice of words because they shape the readers reactions. In addition‚ describing daily details can also enhance the reader’s understanding of the story. David Richards uses general and simple words and language in his novel‚ Nights Below Station Street in order to give the readers a better understanding of the novel

2013 The Pleasure Scale As we go through life we will experience different events that will help shape the scales that we use in life. Biss talks about how pain is our own experience and no one else can feel the same intensity of pain that we feel at any given point in the day. I believe that it can also be turned around no one can feel the same type of pleasure that I feel. There is no way that I can write a scale of pleasure that fits every person that is on the earth; the only scale that I can make

Introduction: The purpose of this experiment is to test if altering the pH of the milk will trigger a hydrophobic reaction. It will also give me a better understanding of the scientific method‚ hydrophobic reactions‚ and how pH affects substances. If the vinegar and salt are added to the heated milk‚ then the milk will curdle. I came to this conclusion based on common knowledge and the text introducing the experiment. I have not made cheese at home before‚ but I have made Hamburger Helper meals

Beck Hopelessness Scale General Information The Beck Hopelessness Scale (BHS) was developed by Aaron T. Beck and Robert A. Steer. First published in 1988 and revised in 1993‚ the BHS is a 20 item scale measuring pessimism and optimism. The instrument is designed to be self-administered‚ or verbally administered if necessary‚ to individuals between the ages of 17 and 80 years of age and takes approximately five to ten minutes for completion. Individual’s true/false answers provide evidence to

Lab #6: pH Effects and Enzyme Concentration on Catecholase Activity Abstract: This experiment examined the effect on how the changes in pH balance of potato juice affected the enzyme activity‚ structural stability and solubility. Introduction: Enzymes are macromolecules that allow chemical reactions to occur. They function as biological catalysts. A catalyst is a substance that is involved in‚ but not changed by or consumed in‚ a chemical reaction. The amount of energy required for a reaction

CLASSROOM ACTIVITIES ART If you are the art area parent‚ it is very important for you to be on time. An important part of our school day is greeting each child at the door. If the art area parent is late‚ often the teacher must be in that area and cannot be at the door to greet the children. Also‚ many children run in and immediately want to do art. Children enjoy the process-- the doing-- experimenting with the art activity. The end product is not the important part of the activity.
