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

technique is: Number Moles Concentrated Solution = Number Moles Dilute Solution. An instrument called a spectrophotometer detects the amount of light that passes through the sample and the percent transmittance can be recorded from the meter. In the lab‚ multiple homogeneous solutions are made. There was not a way to determine the differences in concentrations‚ but the Spec 20 made it possible to measure the difference. The Beer-Lambert Law is a graph used to record

An operating system is a considered a set of programs that schedule tasks‚ assign storage and presenting an interface to the user. There are many operating systems to choose from. Some are created for personal use‚ some for business use‚ and some can be used for both. One of the biggest differences is whether the operating system is open source or closed source. Operating systems are created with programming code. Programmers are responsible for writing the source code‚ which is compiled into executable

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

Closed adoptions are adoptions in which the birthparents of the adopted child have no contact with the child after he/she is adopted or with the adoptive parents. No identifying information is provided to the adoptive family or the adopted child. Closed adoptions are controversial because they basically cut off all connections between the child and the birthparents. The child may never know who their birthparents are and they may have many questions that may remain unanswered. Many people think

reproductive. Orientation is when the organism is placed in their beneficial environment consisting of two behaviors‚ taxis (movement directly towards or away something) and kinesis (random movement). Reproductive is detected using drosophila in this lab‚ it consists of finding courting and mating with another of the species Agnostic behavior is found in a situation where the animal feels threated by another‚ leading to the organism looking bigger or more threatening to the opponent. Within the Agnostic

April 19‚ 2011 The choice of an open vs. closed adoption is one of the most important decisions a mother can make during the adoption process. For both processes an agreement is crafted to detail the rights of the birth parents in the life of the baby following the adoption. There are many pros and cons to both options. Both can be seen and evaluated in the following articles that clearly explain and discuss these two options. Also‚ another form of clarification is the textbook‚ Marriages and Families
