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

TITLE OF EXPERIMENT 2 : DILUTION 2.1: OBJECTIVES Upon completion of this experiment‚ students should be able to: 1. determine the concentration of coloured solution such as FeCl3 by using dilution and colour differentiating (colorimetric) techniques. 2.2: INTRODUCTION Concentration can be expressed in many different ways such as percentage volume and percentage weight etc. In laboratory‚ normally concentrations were expressed as molarity and normality. Molarity is the

Introduction! ! The Michelson Interferometer is commonly used to determine the wavelength of light or measure very small distances. It was invented by Albert Abraham Michelson and is commonly used in optical interferometry‚ a branch of physics involving a family of techniques one could use to extract information about waves by superimposing them. ! ! The original application of the Michelson Interferometer was to the famous Michelson-Morley experiment in 1887. Prior to Einstein’s

“The Rat Trap” Literary Analysis Plot Summary: “The Rat Trap” by Selma Lagerlöf describes the life of a man who sells rat traps. The-rat trap peddler realizes that the whole world is a rat-trap. He falls into life’s rat-trap‚ starting when he stays at an old man’s house and succumbs to the temptation of stealing the man’s money. He avoids the town and wanders through the woods to escape being caught by the police. The rat-trap peddler stays at a furnace‚ where the ironmaster talks to him‚ thinking

healthy five-week old albino Sprague Dawley® Outbred rats: (24 females) and (24 males) purchased from Taconic Biosciences‚ Inc. one month prior to the experiment. The rats were purchased one month prior so that they can be examined by a veterinarian to make sure they are healthy before the start of the experiment. Once the rats were deemed to be healthy they were then separated into their according groups in order to start the experiment. The female rats were separated into four groups‚ three experimental

Conclusion As previously discussed throughout our report Red Stone is currently facing many issues within their company‚ they are unable to deliver their finishing projects on time and remain on budget. A number of gaps have been identified; these gaps have been that cause of all the issues. By determining where the gaps are we are able to act efficiently and effectively to complete all projects successfully and on or before the due date of the project. After analyzing the survey data and compiling

The Charge/Mass (e/m) Ratio of the Electron PHYS 0212: Introduction to Laboratory Physics Fall 2012 Abstract The experiment conducted demonstrated correlation between the charge and mass of an electron and the behavior of magnetic fields. The lab was divided into four parts. The first three parts were conducted with a compass that was used to locate the magnetic field lines around a bar magnet‚ a solenoid and then a pair of Helmholtz coils. As a result of these trials‚ our observations found

eat almost anything they can swallow‚ including household scraps and pet food‚ but most of their diet consists of living insects. Rats are medium-sized rodents that are part of the mammal family. Rats are quite similar to mice but with a more distinct look. Their fur colour and differ between white to a black. The average length of a rat is between 13-18 cm. Rats can eat pretty much everything humans eat‚ meaning that the rat’s diet consists of household scraps‚ grains‚ seeds‚ and other small
