The Effects of Caffeine on the Heart Rate of Daphnia This lab was designed to show how caffeine affected the heart rate of daphnia after exposing them to different concentrations of caffeine for ten minutes. Caffeine is a stimulant‚ which‚ in humans‚ causes heart rates and blood pressure to increase. Its effects range from mild alertness to heightened anxiety and body tension. We wanted to see if caffeine affected the daphnia’s heart rate in the same way. We filled three containers with three different

Introduction: Heart Rate is defined as the amount of times a person’s heart beats in one minute. A resting heart rate is the person’s heart rate prior to any activity or exercise. As activity increases‚ the heart rate will increase in speed. An increased heart rate is essential as it replaces oxygen in the muscles that is used during said activity and gets rid of excess carbon dioxide through the blood stream. Blood pressure is the force of the blood pushing on the walls of the veins and arteries

Determination of a Rate Law Megan Gilleland 10.11.2012 Dr. Charles J. Horn Abstract: This two part experiment is designed to determine the rate law of the following reaction‚ 2I-(aq) + H2O2(aq) + 2H+I2(aq) + 2H2O(L)‚ and to then determine if a change in temperature has an effect on that rate of this reaction. It was found that the reaction rate=k[I-]^1[H2O2+]^1‚ and the experimental activation energy is 60.62 KJ/mol. Introduction The rate of a chemical reaction often

taxes investors pay on dividend income. Currently‚ any money an investor receives when a stock she owns pays a dividend to its investors is added to her total income at tax time. So dividend income is treated the same way‚ and is taxed at the same rate‚ as income from working. If the Bush plan becomes law‚ dividend income will no longer be added to an investor’s total income. As a result the dividends become exempt from taxation. The exact details of the plan are not currently known‚ because it has
