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

Laboratory Report The Plasma Membrane I. Introduction The Plasma membrane is the edge of life‚ the boundary that separates the cell from its surroundings. It controls the traffic of materials in and out of the cell. (Reece‚ 2011). It is incredibly thin that is very vital in maintaining the integrity of the cell. Not only does the plasma membrane bind the other organelles‚ it also forms a dynamic structure which gives them their remarkable activity and selectivity. (Hickman‚ 2008). Diffusion

Wave Nature of Light Objective: The purpose of this lab is to investigate interference‚ otherwise known as the diffraction of light. A beam of light acts a wave‚ and we are able to use equations so calculate the wavelength of the light used. The diffraction of a straight edge demonstrates that light waves bend around straight edges‚ allowing light to enter an area of shadow. When waves are superposed‚ they reinforce each other when crests are in phase and cancel out when they are not in phase

Black Rat Biology Honors Paper The Rattus Rattus (black rat) is one of the most problematic invasive species in the world. Covering 80% of all archipelagos and are found on six continents. Black rats are mainly found on tropical islands such as the Galapagos‚ Hawaii and most of the islands in Central America. Rats prefer to live in areas filled with forests and shrubland‚ but can live on minimal vegetation. Scientists have been able to exterminate this invasive species from most temperate and sub

RAT POW Problem Statement: I this POW we were assigned to find the population of the exponential growth of a rat population‚ residing on a perfect‚ utopian island after a year. Organisms will flourish prosperity on the Island and no deaths would occur. The journey began when merely 2 full-grown rats‚ the one original male and female‚ arrived on the island. Their offspring would be determined by the following: Every day from January 1st‚ the original mother would give birth to a liter of

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
