Purpose: The purpose of this lab was to see how the changes in exercise intensity affect the rate of metabolism within the body. Methods: In this lab‚ indirect calorimetry was used to measure metabolic rate by calculating caloric expenditure by the measurements of oxygen consumption. The variables measured were the fraction of oxygen expired‚ the fraction of carbon dioxide expired‚ and the total volume of air inspired. This experiment required the participation of two volunteers. First‚ the variables

Some control variables were the amount of seeds given for each solution‚ amount of sunlight‚ and the amount of days allowed to grow. 3) The effect of pH on seed germination was an obvious pattern. The solution that had a pH closer to seven such as water (7) and coffee (7.5) germinated all five of their

Introduction In this experiment‚ the environment of the enzyme was altered‚ by increasing or decreasing the temperature‚ pH and concentration. The purpose was to observe if and how the enzyme would react to such changes. This experiment tested whether heating or cooling a catalase would increase

Engineering B45 Concrete Lab Report Introduction: Concrete is a mixture of sand and rock or similar inert material (aggregates) held together by a cementing material. Usually the cementing material is Portland cement‚ but sometimes binders such as asphalt or gypsum are used‚ in which case the concrete may be called asphaltic concrete or gypsum concrete. Properties of concrete are governed not only by the properties of its ingredients (cement‚ water‚ sand‚ and coarse aggregate) but also‚ to a great

Lab Ex#8: "Enzymes: Catalysts of Life" INTRODUCTION Enzymes are protein organelles where chemical reactions take place to generate energy within our cells. Without the energy produced from the cell enzyme activity‚ we would not possess the catalyst activity necessary for energy to produce movement. Each enzyme performs a specific function within our bodies. Those functions performed can be significantly altered with the introduction of variables outside their environment. Variables‚ such as temperature

9/23/12 Lab Report #1 Meter Reading Summary The objective of this experiment was to learn how to read different meters like the D.C. volt meter and the D.C. amperes meter. In all meters each big line is a major division and each little line in between is a minor division‚ and if there is a line smaller than the minor division lines then that would be a sub minor division. Each meter has a low‚ medium‚ and high range. For example on the D.C. volt meter the ranges go from top to bottom 150‚ 15‚
