Experiment 4A: Determination of a Partition Coefficient for Benzoic Acid in Methylene Chloride and Water Experiment 4B: Solvent Extraction I: Acid-Base Extraction Using the System Benzoic Acid‚ Methylene Chloride‚ and Sodium Bicarbonate Solution Objective A: To accustom participants (students) to general procedures that are used to obtain a partition coefficient at the microscale level. We will gain experience in such practices as the transfer of microliter volumes of solutions with a Pasteur filter

Introduction to Microbiology – Case Study 1 Kristen Alejos You are working as an emergency room nurse in Topeka when a mother brings in her 8 year old son because of severe‚ bloody diarrhea. When questioned‚ the boy said that it hurts when he goes to the bathroom and his mother said he had vomited in the previous two days. When asked about their previous movements‚ the mother and son both mentioned a backyard barbeque that had taken place 6 days earlier. The boy complained that his mother

Name Class Date Guided Inquiry • Skills Lab Chapter 11 Lab Modeling Meiosis Problem How does meiosis increase genetic variation? Introduction Most cells in organisms that reproduce sexually are diploid. They have two sets of chromosomes and two complete sets of genes. Gametes are an exception. Gametes are the cells that combine during sexual reproduction. In animals‚ these cells are called sperm and eggs. Gametes are haploid cells with only one set of chromosomes. Meiosis

Biology was fascinated me tremendously particularly when I was introduced to field of microbiology. I used to wonder how these primitive microbes grow and communicate with each other. Theoretical knowledge of microbiology grabbed my attention and made me curious about these tiny microbes which we cannot be seen through our naked eyes. Therefore I decided to pursue my higher studies and specialisation in microbiology. I started my graduation

Family: Enterobacteriaceae Genus: Serratia Species: Marcescens Abstract Microorganisms are constantly finding ways to resists to antibiotics. For this reason‚ it is important to test and observe unknown organisms in the lab to continually improve the health and well being of society. The objective of this report was to first isolate a single colony of an unknown culture on a LB agar plate. From here‚ a slant was made and used for multiple types of testing in order to

Objective: One objective was to figure out if the burnt Mg ashes weigh more than the product which is Magnesium Metal. Another objective was determining the formula of the compound that results when Magnesium and Oxygen react. Theory: The purpose of this lab was to confirm the chemical formula of magnesium oxide by comparing the masses of pure magnesium solid prior to any reaction and magnesium oxide solid after a reaction between all of the magnesium and oxygen from the air when heated from a Bunsen burner

Pets as carriers of soil inhabitant microbes into our homes GIZELL VASQUEZ Biology department‚ Pathogenic microbiology‚ Crosby Jones‚ Angelo State University‚ San Angelo‚ TX 76909 There are approximately 78.2 million owned dogs in the United States (1)‚ and according to the United States government the current population of the nation is 308.7 million. The portion of dogs to humans is 4:1. These statistics are of importance because these pets physiologically observed their environment by smell
