Banana Oil Lab Report Jesse Bradford 7/10/14 MTWR Section Introduction In the banana oil lab we began with isopentyl alcohol + acetic acid isopentyl acetate + Water. We needed for this experiment a hot plate‚ clamps‚ pipette‚ 5mL vial‚ caps‚ hoses and a thermometer. Upon starting‚ our group set up an open system experiment that allowed gases to be released to avoid pressure build up. We mixed together to molecules‚ 1.0mL of isopentyl alcohol‚ 1.5mL of acetic acid

F3.3 – LIMITING FACTORS • a factor that causes popn growth to decrease • two basic types: 1. density-independent factors 2. density-dependent factors 1. Density-independent factors • an abiotic event that affects all popn’s in the same way‚ regardless of popn density • e.g. fires‚ earthquakes‚ storms‚ temperature extremes… 2. Density-dependent Factors • a biotic interaction that varies in its effect on popn size‚ depending on the density of the popn involved • have greater impact on denser popn’s

EXPERIMENT NO. 1 INTRODUCTION TO LAB INSTRUMENTS. 1. BREADBOARD We should be familiar to the following things about a breadboard: * What is a breadboard and what is it used for? * How does it work? * Setting Up. * Limitations. What is a breadboard and what is it used for? A breadboard (or protoboard) is usually a construction base for prototyping of electronics. The term "breadboard" is commonly used to refer to a solderless breadboard (plugboard). It was designed by

Purpose: To determine the percent magnesium by mass in magnesium oxide and to observe if the percentage composition is constant by comparing class results. Hypothesis/Prediction: The percent composition by mass of magnesium in magnesium oxide will not change significantly with each group that conducted the experiment. The composition of each substance should stay the same and any differences must be due to some error.

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

INTERPRETATION OF RESULTS: This experiment circles around with the Newton’s second condition of equilibrium in rotational motion. It describes by net torque acting on a body which is zero. The ability of the body to rotate in a certain direction is varied according on how much torque is applied. To prove that‚ a beam that is subjected to two forces is balanced by adjusting the perpendicular distances. When applied force is weight‚ modification in masses added is also done. Once equilibrium is achieved

Effects of Electrical Stimuli and Injected Reagents on Frog Hearts Melissa Higdon Section 05‚ Group 01 November 19‚ 2013 Introduction: The heart is a very complex muscle for all species. It is responsible for sending oxygenated blood throughout the body as well as sending deoxygenated blood to the lungs‚ and continuously circulate this way for as long as we are alive. Many things can be effected‚ for example how fast the heart beats or how much

cheese. Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress

Unknown Lab Report #1 Unknown #1 April 25‚ 2012 Microbiology Spring 2012 MCB2010C Unknown #1 Introduction Identity of a microorganism has proven to be very significant. Doing so can help identify diseases and created treatment and cures for such diseases. As a result‚ various laboratory tests were performed to an unknown microbe (Unknown #1) found in the water of a nearby pond. By identify the microbe‚ the safety of the water will be known to those around it. Materials and Methods
