tutor for all subjects including physics and math. This has taught me how to work with others efficiently and has given me a deeper understanding to these subjects. Moreover‚ I am currently participating in the M3 Math Challenge that takes large problems and gives them to small groups of students to solve using knowledge and creativity. Doing this challenge helps me understand teamwork and how it is necessary for large projects and how to lead these teams. During all of my school years I have been a High

Brooke Strowd AP Biology Ms. Butler 28 January 2013 I. Title: Effect of a Catalyst on Reaction Rate II. Introduction: The basis of the experiment is the enzyme; an enzyme is a biological molecule that acts as a highly selective catalyst. By combining with a substrate‚ an enzyme is able to create a new product that helps the body function. (Ex. Lactose/Lactase) A substrate is a molecule an enzyme acts upon‚ the two combine at an area called an active site. This active site allows induced fit

Dengue fever can be caused by any one of four types of dengue virus: DEN-1‚ DEN-2‚ DEN-3‚ and DEN-4. You can be infected by at least two‚ if not all four types at different times during your lifetime‚ but only once by the same type. You can get dengue virus infections from the bite of an infected Aedes mosquito. Mosquitoes become infected when they bite infected humans‚ and later transmit infection to other people they bite. Two main species of mosquito‚ Aedes aegypti and Aedes albopictus‚ have

Effects of SO2 On Fermentation Rates Purpose SO2 is the primary inhibitor for natural microbiological growth in wine. It prevents the browning of juice by inhibiting phenol oxidase activity and kills the natural yeast cells for the utilization of fermentation-controlled commercial Saccharomyce strands (Boulton et al. 1996). SO2 is pH and temperature dependent and can exist as several forms. The bisulfate form (HSO3-) can complex with soluble solids such as anthocyanins and acetaldehydes to become

Part I: Briefly evaluate how Google’s Prediction Markets have worked to date. To what extent have the markets been successful or unsuccessful? 250 When the five Googlers got together to start with this project‚ their main objective was to launch an internal prediction market and test if crowds would make more accurate predictions than individuals’. To determine if this project was a success or not we need to determine our parameters of success. Moreover‚ we also think that the success will be
