Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

Evaluation of antidiabetic and antimicrobial activity of jasminum grandiflorum leaves INTRODUTION 1.1. The pancreas and insulin formation The pancreas is an elongated organ situated next to the first part of the small intestine. It is both an endocrine gland that produces hormones‚ such as insulin and glucagon‚ and an exocrine gland producing digestive enzymes‚ such as trypsin and chymotrypsin (Martini‚ 2004). It is located behind the stomach‚ between the spleen and the duodenum (see Figure

The commandments are absolute pronouncements of right and wrong in all situations In Mormon 9:9 it says: "For do we not read that God is the same yesterday‚ today‚ and forever‚ and in him there is no variableness." This expresses that for every situation the commandments are the same. There is a clear example that shows that the commandments are the same regardless of the situation. We are commanded to be baptized for the remission of our sins. It is a requirement to enter the waters of baptism to

Enzyme Catalase Activity in Reaction with the Substrate Hydrogen Peroxide Abstract We performed these experiments to observe the effects of enzymes on the rate of reactions. We tested and compared the activity of the enzyme catalase on the substrate H2O2 in various states and percentages‚ and observed the absorption values of the enzyme-substrate relationship at different concentrations. Our results show that the more substrate available‚ the quicker the reaction will happen except in one test

your own words‚ describe the overall goal of the storyboarding activity. The storyboarding was to demonstrate of how a muscle contracts and how it goes back to relaxation‚ but more importantly how each part does it function for this to happen. I was a little confuse about how the process happens‚ but I’m the type of person that can learn more when I have a visual so I think it was really helpful to to do the storyboarding. In today’s labs I learned how the channels open and releases and let in the

My lab group studied the effect of PH on reaction rate/ enzyme activity measured by foam height. PH is the measure of the concentration of hydrogen ions in a solution. The higher the hydrogen ion concentration‚ the lower the pH. Every enzyme has an optimal PH‚ meaning they have a very small window in which they are most active. Our enzyme (potato smoothie) had an optimal PH of 7.0-7.5. We know this because we measured the enzyme’s reaction rate by measuring foam height. The largest foam height we

Factors Affecting the Rate of Enzyme Activity Justin Hunter G. Kim September 16‚ 2011 September 26‚ 2011 Abstract Catalase is a common enzyme found in nearly all living organisms that is frequently used by cells to rapidly catalyze the decomposition of hydrogen peroxide into less reactive oxygen and water molecules. Catalase is a protein that is most commonly found in the liver. The purpose of this experiment was to determine the effect that changes in temperature and pH have on the function

called the sarcomere‚ these are what gives the tissue of a skeletal muscle its appearance. The mechanism within muscle contraction is known as binding and ratcheting this allows the muscle to shorten and contract. If the specific muscle doesn’t need to contract‚ the strands of proteins that are not needed wrap themselves around
