Findings Analysis to determine the sex of our case study AFA was done using a physical exam karyotyping and PCR-based sex testing. The results from our physical exams on AFA showed well-developed female external genitalia‚ presence of breasts‚ no menstrual cycle‚ and no facial or chest hair. This led to a conclusion that AFA is a sterile female. The results from the Karyotype Analysis showed presence of 22 pairs of autosomes chromosomes and two X’s revealing that she is female. Lastly the PCR-based

THE GRAVIMETRIC DETERMINATION OF SULFATE Learning Goals. 1. To determine the amount of Sulfate in an Unknown sulphate sample. 2. To perform and develop skills in precipitation Gravimetric method of quantitative analysis. DISCUSSION: Gravimetric analysis is one of the oldest analytical techniques and for this reason is referred to as a "classical method." Gravimetric procedures are usually very accurate‚ but more tedious than other methods. The only major equipment needed

Determination of a Rate Law and Temperature Dependence of a Rate Constant By Marvin Coleman March 7‚ 2011 Abstract: From the shown calculations & graphical analysis‚ the experimentally determined rate law is rate = K[I-].969 [H2O2].991 and the experimentally determined activation energy is 59.50 kJ/mole. Introduction: The rate of a reaction varies at different temperatures and reactant concentrations. In this experiment‚ the orders and dependence of the rate constant of the products

Partner’s Name: Shanygne Swann Lab Report #2 Title of Experiment: Static Friction and Limiting Equilibrium Brief Theory of Experiment: In limiting equilibrium‚ the sum of the forces on block X and on the hanging masses (load) Y is zero. The load is increased to a value until block X just slides at constant speed when the table is tapped. Tapping the table destroys the limiting equilibrium condition momentarily by altering the balance between tension (T) in the string and the maximum force

Arjun Pahwa Math Research Paper The Application of the Nash Equilibrium in Game Theory to Microeconomics ! One of the most challenging problems a business owner comes across is the amount of a certain item he or she should stock and the price at which to sell it. Many factors play into finding this appropriate price. These include the cost of stocking the item‚ the projected demand‚ and what the competition is pricing the same item at. The latter of the three factors is considered to be the most

Chemistry Dr. Isotone Lab 1: Determination of the Empirical Formula of Silver Oxide Lab Objective: In this experiment‚ the percent composition and empirical formula of silver oxide will be determined. Silver oxide will be heated until it decomposes to silver metal and oxygen‚ and the percent calculation and empirical formula can be calculated based on combining the ratios of silver and oxygen in the reaction. Summary of Lab Procedure: 1. Set up Bunsen burner on a ring stand
