The Purpose of lab 1.4 Measuring Volume by Displacement of Water was to determine the fraction of air in different granulated solids. The lab cocised of one test done on four different granular solid; with up to 3 trials on each solid. When all tests are done and put in tables‚ and the calculations are made‚ the conclusion is that grain size does not affect that fraction of air. To be able to find the fraction of air‚ 3 measurement had to be taken‚ the volume of the solid with air‚ the volume of

fractionation is a very important procedure in cell biology and can be very useful for studying different organelles. By fractionating‚ we mean separating or dividing the cell into different component parts. Fractionation results in a series of fractions with only one highly purified organelle or protein present in each one ideally. Fractionation can be done by many different methods including size exclusion chromatography‚ charge‚ density‚ and immunoprecipitation; these are just a few. The two most

Ali A. Mohammed Cell Structure and Function 16 October 2014 Gel Filtration and Electrophoresis Objective The essential goal of the experiment was to separate proteins in a solution based on size in different fractions. The relative protein content for each one fraction was found through the utilization of an amido black-based protein assay. Later in the trial polyacrylamide gel electrophoresis was utilized to separate BSA from hemoglobin. Methods I. Gel Filtration and Protein Assay: 1. A slurry

to. So I chose to design my unit plan was based on fractions. My intention was to use what would seem as minute concepts seen in fractions and show how these minute concepts are applied to everyday life. After teaching this lesson I wanted my students to be able to recognize and understand fractions when they came in contact with them whether in school or out of school. Learning about fractions is important because they will encounter fractions in all walks of life. Based on Jean Piaget’s theory

where P and Q are simpler expressions (usually polynomials)‚ and the denominator Q is not zero. A rational number is any number that can be written in the form a/b‚ where a and b are integers and b ≠ 0. it is necessary to exclude 0 because the fraction represents a ÷ b‚ and division by zero is undefined. A rational expression is an expression that can be written in the form P/Q where P and Q are polynomials and the value of Q is not zero. Some examples of rational expressions: -5/3; (x^2

of these elements shifted the equilibrium to the right‚ ultimately increasing the yield of alkene‚ this is also known as Le Chatelier’s Principle. Then both fractions were washed with 1.5mL of 5% aqueous sodium bicarbonate‚ the reason or this is that the sodium bicarbonate gets rid of the excess acid present. In order to analyze the fractions‚ both were put through gas
