------------------------------------------------- Enzyme Pre-Lab Harry Kang 9/26/12 1) The purpose of this lab was to determine the rate of enzyme activity under variety of different conditions‚ such as‚ different amount of drops of enzymes and different temperature of water. The class measured the pressure in the test tube during the reaction of the substance with‚ 1.5 ml of H2O2‚ 1.5ml of H2O and different amounts of enzyme drops‚ to determine how much oxygen gas is produced during the reaction

The Origin of the Chicken and Chicken nuggets Exposition Chickenlandia was a quiet village in Ancient Greece with only a handful of inhabitants. Its main focus‚ for girls and boys‚ was archery. They valued it because of its uses in hunting and self protection. In the village‚ there was. In the village there was one main dirt road‚ and there was one blacksmith‚ for making bow and arrows of course‚ and for no reason the whole village smelled of chutney. The elders of the village always spoke when

change‚ means there is no net loss or gain of water. Introduction This study shares the results of an effort to understand diffusion and osmosis in general. It focused more into osmosis in plants cell‚ and how to indirectly measure osmolarity in potato tuber tissue. Osmosis is the diffusion specifically of water across a membrane. Diffusion occurs when certain substance‚ such as an ion‚ is more concentrated on one side of membrane. If the membrane allows this ion through‚ the ions will move from

Running head: LAB 5: INVESTIGATING AN ENZYME-CATALYZED REACTION Lab 5: Investigating an Enzyme-Catalyzed Reaction September 24‚ 2014 Principles of Biology 120.601 Mrs. Annemarie Duncan Abstract: (Burmania) This experiment was performed in order to examine ways in which a potato catalase enzyme reacts to various assays with differing variables. To do so a baseline assay (undiluted extract and room temperature H2O2) was used within the experiment with only one other variable changed in

THE IRISH POTATO FAMINE Pre-Famine History The potato was introduced to Europe sometime in the 16th century. There are many theories on how it arrived‚ but the one with the most credibility is from a case study done by Theresa Purcell. She explains how the white potato‚ also known as the Irish potato‚ originated in the Andean Mountains and was brought to Europe by the Spaniards. The potato was originally classified in the same family as the poisonous nightshade so people refrained from eating

increase the reaction. As I increase the surface area of the potato the gas given off from the reaction will increase. Therefore to sum things up‚ my hypothesis is when the Independent variable increases so will the dependant variable. Independent variable: - Surface area of potato Dependant variable: - Gas Controlled variable: - Equal size of potatoes used - Using measuring cylinder Equipment used: - Gas collecting kit - Potato - Stop watch - Test tube - Distilled water - Hydrogen

How do our Reactions to Obstacles and Hardships Help to define us as Individuals? As our fragile minds go through adolescence and on to adulthood‚ we face obstacles that are put in our way that shape and define us as human beings. Some people tend to crack under the pressure others trudge through it challenging and pushing themselves to their limits. We aren’t always alone we have people that are there to help us along the way and sometimes they leave their mark on you like on the last shot in

Chlamydia is the most common bacterial sexually transmitted infection (STI) in Canada. When left untreated‚ it can lead to painful physiological problems and sterility defects. Despite being in decline for many years‚ rates of chlamydia infection have risen steadily since 1997. These rising rates show that people are not using safer sex methods on a consistent basis. This STI is transmitted through vaginal‚ anal‚ or oral sex‚ and can also be transmitted from mother to child during childbirth. Chlamydia
