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

LSM1102 Lab Report Introduction Transformation is a process which involves plasmid DNA being bound to the cell surface and the subsequent uptake of DNA by the cell (Panja et al.‚ 2008). For artificial transformation of E. coli cells with plasmids‚ plasmid DNA has to be extracted from bacterial cells using the High-Speed Plasmid Mini Kit‚ which is then mixed with competent E. coli cells followed by heat shock and the streaking of transformed cells on two different types of agar plate (LB and LB+ampicillin)

Chapter 1 Vectors‚ Forces‚ and Equilibrium 1.1 Purpose The purpose of this experiment is to give you a qualitative and quantitative feel for vectors and forces in equilibrium. 1.2 Introduction An object that is not accelerating falls into one of three categories: • The object is static and is subjected to a number of different forces which cancel each other out. • The object is static and is not being subjected to any forces. (This is unlikely since all objects are subject to the force

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

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

is involved with the cannon being fired then the force of gravity would cause the cannon to start to slow down‚ wouldn’t go as far and the direction or trajectory of the cannon ball would be a curved line going down. Purpose: The purpose of this lab is to give the student a better understanding about projectile motion and to understand Newtons theories and laws of motion. We will be firing the plastic ball from the projectile launcher three times from eight different angles from the ground &
