marshmallow because of the fat content of the peanut as opposed to the marshmallow. We will measure it in calories which is the heat required to raise 1 gram of pure water 1 degree C. There is a “calories per gram” on the label of each item and we are also testing to see if those are true. The calories per gram for the marshmallow are 3.2 cal/g. the calories per gram for the peanut are 6 cal/g. Materials and Methods: The materials needed for the experiment are peanuts‚ marshmallows‚ a beaker with ice‚ wire

Organism Paper The unknown organism tested in the Mesa lab was collected from in between the toes of my puppy‚ Riley. The original culture grown consisted of dozens of visibly different organisms of varying colony colors and growth patterns. I chose to test a smaller‚ red colony for my experiments. Based on its gram reaction and oxygen requirements‚ the following tests were performed to reach my presumptive ID: Test Performed Result Gram Stain + Fluid Thioglycollate Strict aerobe Catalase + Nitrate

1. Introduction Microscopy is an essential technique not only in cell biology but natural science as a whole. We compared different types of microscopic techniques ‚ according to the specimen used and the scope of the experiment. Two specimens‚ stained and unstained‚ containing CHO cells‚ were prepared‚ examined and analyzed under the microscope using bright field (HF)‚ dark field (DF) and phase contrast (PH) settings. In addition‚ the four phases of cell division cycle were estimated.. Bright

November 3‚ 2014 Chemistry 1411- 106 Pre Lab Experiment #8 Objective: This Lab will help us to understand oxidation reduction and double displacement through finding the percent composition of pennies. We will also once again be working with titration in this lab. We will titrate the solution until we are only left with a solid form which will tell us about the composition of pennies. Introduction: The weight of a post 1982 penny is 2.5 grams‚ and the percent of zinc is 97.5% leaving only 2.5% copper

Formula of a Hydrate Lab Wednesday October 29‚ 2014 Chemistry Honors Purpose This lab was done to determine the percentage of water in a hydrate‚ which was CuSO4 ?H20. Not only the percentage of water can be found‚ the moles of water can be found per one mole of anhydrous salt. An anhydrous salt is a hydrate that lost its water. Using various lab equipment such as burners‚ crucible‚ and balance‚ and techniques such as the mass-to-mole ratio and mass to percentage‚ the percentage of water in a hydrate

results in the Lab Report. You answered: 426 ml O2/hr 1i. Now that you have calculated the oxygen consumption per hour for this rat‚ you can calculate the metabolic rate per kilogram of body weight with the following equation (note that you need to convert the weight data from grams to kilograms to use this equation). Metabolic rate = (ml O2/hr)/(weight in kg) = ml O2/kg/hr Enter the metabolic rate in the field below and then click Submit Data to display your results in the Lab Report. You answered:

Diffusion and osmosis go hand-in-hand. Osmosis is generally the same as diffusion‚ however‚ deals solely with water. Osmotic pressure is the pressure of a solution against a semi-permeable membrane to prevent water from flowing into the membrane. In this lab‚ we are going to study tonicity; tonicity is the measure of this osmotic pressure and is the differential of pressure between two solutions separated by a selective membrane. To help identify the relative concentrations of solute particles of different

Mystery Blood Typing Lab Scenario: Police are called to a house where they discover a body near the back door. There is a fresh pool of blood by the victim’s head. Officers question the neighbors and learn that a plumber and an electrician made service calls to the house just hours before. They were able to trace both. They recover a shirt with a dark stains from the service van of the plumber and rags with similar dark stains from electrician’s van. Your forensics lab receives the following
