Joe Schmoe Period 3 March 8‚ 2013 Lab Report: Empirical Formula of Zinc Chloride (ZnCl) * Purpose The purpose of this experiment was to learn how to determine the empirical formula. Empirical means “based on experimental evidence.” * Experimental Design The reaction that occurred was the reaction of the elements Zinc (Zn) and Chloride (Cl) by mixing a piece(s) of Zinc and 50mL of Hydrochloric Acid (HCl). The amount of Zinc was determined to be between 1.00g and 1.25g. As the reaction

Lab Report 1: Natural Selection Introduction: In today’s lab we learned how natural selection and survival of the fitness took place in Darwin theory by testing it out with four different utensils which were Spoon‚ Fork‚ chopstick‚ and clothespin which represent the four different types of bird beaks. Our goal was to see which one utensil ( bird beak) would outcome the other four utensil ( bird beak) by being able to survive with the limit amount of food‚ the environmental chances‚ and see who

I started out as an ignorant 7th grader who barely made AIME to a slightly less ignorant 8th grader who barely made USAJMO. In 7th grade‚ I did not even know what the nine-point circle was‚ and now in 8th grade‚ I am able to prove its existence. In 7th grade‚ I could not work with polynomials and roots very well‚ and now in 8th grade‚ I can use polynomials quite efficiently. In 7th grade‚ I failed the AMC 10 with a pathetic score of 123‚ and now in 8th grade‚ I was able to score well enough on the

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

duties from both the Patrol and CRT sides of the Division‚ I have a complete understanding of how a Patrol Division operates. This includes budgetary considerations‚ staffing‚ personnel issues‚ logistical considerations‚ morale‚ monthly/quarterly reports‚ special projects‚ and significant event response. Other Divisions throughout the agency require their commanders to consider and address these same issues. Having already handled each of these facets myself‚ I will be well prepared to address them

The Virtual Lab – ELISA Test Lab: Immunology 09/04/2013 Instructors: Dr. Charlie Wilson Written by: Dipen Patel I. Objective: The purpose of the lab was to learn the procedure of performing an ELISA test to determine whether a particular antibody is present in a patient’s blood sample. ELISA is an abbreviation for “Enzyme-linked Immunosorbent Assay." II. Introduction: The interaction of antigen and antibody outside the body can be used to determine if patient
