PEES 4200W- Physiology of Exercise Lab #2: Metabolism and Energy Expenditure 1. The Respiratory exchange ratio is the ratio of the volume of carbon dioxide produced and oxygen consumed. The ratio indicates the energy that the subject is expending for indirect calorimetry‚ how efficient the subject ’s body is at utilizing the oxygen inhaled‚ as well as the main substrate being used for energy during varying intensities of exercise. During rest the volume of carbon dioxide was 0.73L/min‚ the volume

Service - Our Responsibility Water and Sewerage Authority (WASA) was established by an Act of Parliament in 1965 to manage the water and sewerage sector of Trinidad and Tobago. An essential component of this mandate is the delivery of a safe‚ reliable and efficient water supply to satisfy the demand of all sectors of the economy. Whilst over the ensuing years there has been a steady increase in demand‚ there has not been the commensurate investment in infrastructure and the identification of alternative

Purpose: To find out the densities and to find out the name of the unknown metals. (Based on the extensive and intensive properties) Check up the words mass‚ volume‚ density‚ extensive properties‚ and intensive properties. Where do the units for mass and volume) come from and what do they mean? What is the density of distilled water? What is Archimedes principle? Does temperature affect the density of a solid? Liquid? Gas? Materials: Safety glasses‚ 10‚ 25 or 50 mL graduated cylinders

1. Introduction: The goal of this lab was to demonstrate the microbiology technique of serial dilutions and how they can effectively be used in experiments. E. coli cells were exposed to UV light for various amounts of time in order to asses the effect on growth and thereby mutations since this cell was modified to not have photolyse no uvr genes for DNA repair and thus can only use the SOS response. Each group then diluted the cells accordingly based on their UV exposure time and counted the cells

Organic Chemistry II Lab 9 Fermentation of a Carbohydrate: Ethanol from Sucrose * Introduction Ethanol is one of the oldest alcohols and also the least toxic one. Industrially‚ ethanol is made most economically by hydration of ethylene. However‚ ethanol that is intended for human consumption must‚ by law‚ be prepared by fermentation. By either method‚ ethanol‚ of course‚ has the same formula‚ structure‚ and properties. The fermentation takes place with the assistance of enzymes from yeast

1. The overall goal of this lab was to carry out experiments that clearly demonstrate the different ways DNA genetic information‚ specifically transduction and conjugation. The first half of this experiment focused on exploring the mechanisms of transduction. This was done by creating a spot titer plate for phage carrying kanamycin resistance and E. coli. E. coli was then proven to have gained kanamycin resistance throughout transduction as demonstrated by its ability to grow on a medium containing
