bridge where the characters and I met and and had an insane connection. My journey with Literature has brought me to a point where I would love to explore deeper into the subject. I would like your consideration to join the AP Literature and Composition class. Below‚ I will describe why I should be in the class‚ what I hope to gain from the class‚ and my favorite book. I hope that after reading this essay‚ you will be convinced why I would be a great contribution in the world of writing and in

For this experiment‚ there will be an optimal point for each factor. I believe that the optimal temperature for the enzyme sucrase will be 37°C because that is the point where the temperature increases the rate of reaction to its greatest point without denaturing it. For the pH test‚ I think that the optimal pH for sucrase will be the pH of 7 because it is neutral so it won’t affect the charge in a negative or positive way. For the denaturation test‚ I think that the optimal treatment for the enzyme

Title: Food Energy Lab Report Date of Activity: 8-28-13 through 8-29-13 Purpose: The purpose of the lab was to measure the amount of energy contained in a gram of certain foods. Hypothesis/Prediction: I hypothesize that some of the foods are going to be difficult to burn. Procedure: 1. Weigh the weight of empty can and food items. 2. Fill can approximately one third full of water. 3. Weigh the can after water is in the can. 4. Take the temperature of the water in the can. 5. Place the

LAB REPORT Introduction: In a chemical change‚ the identities of substances change and new substances form. In an equation the substances on the left are the reactants. The substances on the right are the products. In this experiment the objectives are to observe evidence that a chemical change has taken place. Infer from observations that a new substance has been formed. Identify and record observations that show energy is involved in chemical change observe the color‚ solubility of some substances

The chloride shift is basically an exchange of chloride ions through the capillaries of the system circuit. In the blood plasma‚ there is large amount of carbonic acid and when there is an increase in carbonic acid than the balance of hydrogen ions and carbonate ions dissociate to maintain a balance of homeostasis in the pH of the blood. The red blood cells help to maintain this system by buffering the system of carbonic acid and causing detachment of the above ions. The release and detachment is

Experiment 3 : Preparation of Solutions and Buffers Objectives : 1. To study and understand the principle theory and formula of preparation of buffer and solution. 2. To learn the methods of buffer and solution preparation. 3. To focus on concentration units of molarity‚ percentage of concentration‚ and dilution of solution. Introduction : When a substance‚ called a solute‚ is dissolved in another substance‚ called the solvent‚ a solution is formed. A solution is known as a homogeneous

2. How is the colour related to surface temperature of the star? The correlation between the surface temperature of a star and its colour is due to the phenomena known as black body radiation .A star is a black body‚where it aborbs all the radiation falling upon it.AS its temperatures gets hotter thanits surrounding‚the star radiates its on electromagnetic radiation‚known as black body radiation. This radiation is distributed unevenly but contionously through multiple wavelengths of the electromagnetic

Conclusion: The purpose of this lab was to synthesize and purify aspirin. The theoretical yield was calculated to 3.766g. The actual yield of pure aspirin was 2.863g with a yield of 76%. The percent yield indicates that our synthesis was a success but the yield is low and indicates that some of the aspirin was lost during synthesis. Some reasons for loss can result from human error such as loosing product from sticking on the spatula and the Buchner funnel and several weighings. Also‚ when transferring
