Meiosis and Genetic Diversity in Sordaria 979554296 Biology 110 Lab Introduction: In Israel there exists multiple spots in the mountains called Evolution Canyons‚ which are all located between a southern facing slope (SFS) and a northern facing slope (NFS). What’s particularly interesting about these locations is that despite the two slopes being on opposite sides of a small canyon‚ they exhibit extremely contrasting conditions. The SFS receives multiple times the UV radiation from the sun

Analysis There were in total of 37 dots recorded on the piece of the Ticker Tape. Every

Introduction During the course of this lab‚ we explored whether or not certain processed foods contained Genetically Modified Organisms. Genetically modified food is an important subject in the world today. Ever since Flavr Savr came out with their tomatoes grown from genetically modified seeds in 1994 genetically modified foods has become ever more popular amongst distributors of produce (Mestel‚ 2013). The world’s population has grown by around one billion in the last decade (US Bureau of the

Thermodynamics- Enthalpy of Reaction and Hess’s Law December 5‚ 2011 Kylie Case‚ Emma McKee‚ Rebecca Smith Purpose: In this lab‚ the purpose was to verify Hess’s Law. Theory: Four main topics were covered during this experiment including enthalpy of reaction‚ heat of formation‚ Hess’s Law‚ and calorimetry. The first being enthalpy of reaction‚ ΔHrxn‚ which is the heat or enthalpy change for a chemical reaction. The energy change is equal to the amount of heat transferred at a constant

water will be measured using a graduated cylinder. The 50g of catalase and the 50ml of distilled water will be put into a blender and blended until liquefied. The catalase solution will then be introduced to a Buchner funnel filtration system to separate the catalase extract from any solid particles left over from the blending process. This step will be repeated until all of the catalases have been blended and filtered. Next‚ 5 ml of hydrogen peroxide will be measured out using a graduated cylinder

Impurity Lab Report Aim: To find out the difference of the boiling point and melting point when adding impurity (salt) to water. Diagram: Method: 1.Set up the apparatus as shown in the diagram 2. Get a known amount of ice in the beaker (half full)‚ and a known amount of salt in another beaker 3. Measure the temperature (melting point) of the ice without adding any impurity (salt). 4. Measure the temperature (melting point) of the ice after adding the salt into the beaker. 5. Heat up

April 04‚ 2014 Fisher Esterification Introduction: Esters are one of the most common derivatives of carboxylic acids and are widely distributed in both nature and industry. A Fischer Esterification is the formation of an ester and water from alcohol and an acid. It is the simplest means of synthesizing an ester and requires the reaction of a carboxylic acid and an alcohol. The general reaction of Fischer esterification is‚ CH3CO2H + ROH ↔ CH3CO2R + H2O (reaction1) CH3COOH + ROH ↔

Lab Report Procedure 6.1: Perform Benedict’s test for reducing sugars. Introduction: Benedict’s tests allows for the detection of the presence of reducing sugars. All monosaccharides are reducing sugars since all of them have active carbonyl group. Some disaccharides that are exposed to a carbonyl group are also reducing sugars but less reactive than monosaccharides. By mixing the sugar solution with Benedict’s solution and heating them‚ a redox reaction will occur. The copper (II) sulphate

pretty unpopular in the British press‚ quite aside from the fact that he’s been convicted of a felony. (His scandalous lifestyle is straightforwardly presented here.) Whatever the man’s personal flaws‚ however‚ his first book‚ Not a Penny More‚ Not a Penny Less‚ is a lot of fun. The story begins wheh Harvey Metcalfe‚ a self-made American millionaire‚ finalizes an elaborate scam in which he cheats four strangers out of a million dollars. All four of them thought they would be rich; the

This lab experiment investigates the effect of listening to different types of music on one’s pulse. The experiment relates the circulatory system to the pulse as it measures how quickly the heart contracts and releases blood. Pulse is measured in beats per minute (bpm). One’s pulse is loudest near the heart‚ because there is more pressure closer to the heart. In contrast‚ one’s pulse is quieter the further away it is measured from the heart‚ because there is less pressure the further the distance
