Toxicology Lab 1. In this investigation‚ a wide range of concentrations of Sodium Chloride (NaCl) solution were created and the effects that they had on radish seeds were tested. This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. The goal of this experiment was to determine a correlation between toxicity and seed germination/radicle

Cross-Cultural Communication Research Paper Bulgaria versus Japan Ivan Ivanov November 30‚ 2011 MBA 501: Business Communications & Research Methods According to Benjamin Whorf’s theory (1956)‚ the nature of the language we speak affects and determines our behavior and way of thinking. Japanese is a very good example of how this theory works. Japanese people use their language in a completely different way from anyone else and their behavior makes sharp contrast to the rest

garden pees in carefully planned experiments. He chose to work with peas‚ because they come in several varieties and had many different traits about them. Mendel was focused on controlling mating between the plants (Campbell). Through the selective cross-breeding of common pea plants (Pisum sativum) over many generations‚ Mendel discovered that certain traits show up in offspring without any blending of parent characteristics. Each variety has a different color flower‚ one purple and one white. This

Cross contamination is critical matter and does go unnoticed. It’s not something many think about when out eating out‚ or preparing there own food at home. The remainder of this essay will include what is cross contamination and its symptoms‚ what prevention methods should be taken along with examples of food being contaminated. When an individual decides to eat out or eat at fast food restaurant’s they do not think of the harmful effects that could occur when an individual’s food is being handled

Lab 5 The Diffraction Grating Chinua McDonald Objective: To measure the wavelength of light with a diffraction grating. Theory: The two types of diffraction gratings are the transmission and reflection gratings. They are made by ruling on a piece of glass or metal a number of evenly spaced lines with a fine diamond point. Diffraction phenomena can be analyzed in terms of Huygens’ principle‚ according to which every point on the wave front of a wave should be considered as a source

indicated by a very pale pink color. To calculate the molarity of NaOH‚ the following equation was used MNaOH x VNaOH = MKHP x VKHP therefore the molarity was .125 M. INTRODUCTION This lab experiment covers the preparation of standard solution and the acid/base titration. The first part of the lab is to prepare a standard solution of Potassium hydrogen per. A standard solution is a solution of known concentration‚ in which it is prepared using exacting techniques to make sure that the molarity

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

This lab was the study of monohybrid as well as dihybrid crosses. A monohybrid cross is the study of a certain trait whereas a dihybrid cross is the study of the mating experiment between two organisms that are identically hybrid for two traits. ( Reference 1 ) This lab was done to determine the genetic mutations after each generation and to observe the ratios. As each generation of fruit
