Morgan Kimmerle Monday Lab Dr. McCorkell Abstract The purpose of this study was to cross and analyze the reciprocal crosses of wild flies and mutant flies. In this lab Drosophila melanogaster commonly known as fruit flies were used to understand some important genetic principles that were once proposed by Gregor Mendel. Mutant traits can be autosomal dominant‚ autosomal recessive traits‚ or even sex-linked dominant and sex-linked recessive. F1 and F2 generations were obtained by performing

Title: Esterification Objective: To synthesis acetylsalicylic acid by esterification. Introduction: A pleasant‚ often fruity‚ odor is characteristic of some of the simpler esters. Ethyl butyrate smells similar to pineapples‚ the odor of n-propyl acetate is reminiscent of pears and isopentyl acetate has a strong banana fragrance. Esters are derivatives of the carboxylic acids and contain the following functional group: The synthesis of an ester can be accomplished in one of several ways. An esterification

recording the mass‚ volume‚ temperature‚ and volume. This provided the mass of 1.6 grams which was found by subtracting the mass of the Erlenmeyer flask‚ aluminum cover‚ and rubber band from the mass of the Erlenmeyer flask‚ aluminum cover and rubber band and unknown gas after heating. Then the temperature of the gas was determined by taking the temperature of the hot water which was 94 and converting it to Kelvin by adding 273.15. This is because the gas was heated to the same temperature of the water

Hugh Kim Lab Report: Stoichiometry Lab 1. Prelab Part1. 1) Create no waste = The principle that encourages chemists to not create waste at the first place rather than cleaning it up afterwards effectively shifts the chemistry more environmentally conscious‚ as creating no waste would make the experiment efficient; the reactants will be reduced to only the essential ones and the product will be maximized‚ a change that would make the experiment economic. Also‚ if chemists aim to

Heat capacity of a body is the quantity of heat required to raise the temperature of the body by 1oC. The specific heat of a substance is the heat capacity per unit mass. Thus‚ heat capacity = mass x specific heat. The specific heat is essentially a measure of how thermally insensitive a substance is to the addition of energy. Heat and temperature are really different quantities. Heat is a quantity of thermal energy‚ while temperature determines the direction and rate of heat transfer to the surroundings

The quality of the silver catalytic surface determine the amount of air used. The following reactions take place CH_3 OH+ 1/2 O_2→HCHO+H_2 O CH_3 OH→HCHO+H_2 The conversion of methanol will be 65 – 75% per pas Silver catalyst process:

Dynamics and the Cardiovascular Physiology experiments both have multiple goals. The first experiment aims to understand how blood flow‚ pressure gradient‚ and resistance relate to one another. To understand this‚ resistance and contributing factors‚ such as vessel radius‚ viscosity‚ and vessel length must be studied. The effects of vessel radius and stroke volume on the ventricular pump should also examined. The experiment also calls for an understanding of cardiovascular compensation. Pump mechanics

Genetically Modified Organisms INTRODUCTION: The purpose of this lab was to identify if non-labeled food products are actually genetically modified foods. Before we could begin testing this theory we first had to gain an understanding about genetically modified organisms in general. This was rather easy because if you have been to any grocery store lately you have without a doubt seen products with labels saying "GMO-free" or even "contains only non-GMO ingredients." GMO actually stands for

The goal in this experiment was to test the effect of adenosine triphosphate in lighting the firefly’s lantern in temperature effects‚ pH effects‚ and salt effect. Materials and Methods Powdered firefly lanterns were obtained from Carolina Biological. The lights in the room were turned off. The dropper from the bottle of ATP powder was removed. A pipette was used

I. Introduction: The purpose of this lab report is to differentiate between of Newton’s Third Law and Newton’s Second Law. Newton’s Third Law states that all forces come in pairs and that the two forces in a pair act on different objects and are equal in strength and opposite in direction. Newton’s Second Law states that the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object being accelerated. Using calculation equations for acceleration
