Microbiology Laboratory Report Identification of Unknown Bacteria 03/10/05- 04/01/05 Authors: Richard Hendricks‚ Jessica Prebish; NMU Abstract: Broth culture 16 was randomly selected by our group and subjected to qualitative tests for taxonomic identification. The culture did appear homogenous throughout the testing period and is currently retained by Northern Michigan University’s department of Microbiology. We suggest that culture 16 is an example of Escherichia coli. Background: Techniques

Lab report As part of my module Nip1002 I was required to perform a set of observational skills which included; pulse‚ blood pressure‚ respirations‚ hand washing and urinalysis and then compare them to previous results. In this lab report I am going to discuss blood pressure in detail. Procedure * Explain the procedure to the patient and gain consent * Wash hands thoroughly following the hand wash technique to prevent the transfer of bacteria * Clean equipment e.g. blood pressure cuff

Acids & Bases Lab Write Up Lab 2 Introduction There are many acids and bases all around us. An acid is known as a hydrogen ion donor (H¯)‚ and a base is known as a hydrogen ion acceptor (H⁺). Acids and bases are represented by the pH scale. The pH scale shows the strength that an acid or base has. This scale ranges from 0-14‚ with 0-6 being acids‚ 8-14 being bases‚ and 7 being neutral‚ such as water. This is defined as the negative log of an ion atom (pH=

- BIOLOGY ASSIGNMENT Aim: To investigate the types of producers and animals in the tidal rock-shelf ecosystem and the adaptations of organisms in that environment. Also‚ to measure biotic and abiotic components and the distribution and abundance of organisms to the tidal rock- shelf ecosystem. Introduction: Long Reef Marine Reserve was established in the 1980’s to protect the extremely diverse marine life that makes the most of this environment. The Marine reserve covers the large rocky

ABSTRACT. In this experiment‚ we test factors which affect friction. We pulled a wood block across a surface to determine whetherthe surface area ofthe block orthe type ofsurface affectsfriction. We found that the surface area of the block did not change the coefficient of kinetic friction‚ while the types of materialsin contact were directly related to the coefficient of kinetic friction. INTRODUCTION Friction is a part of our everyday life. Nearly every movement we make involves friction

Chemistry Lab Report Water Hydration Introduction: A hydrated crystal or hydrated occurs when water becomes tightly attracted to a metal salt base on it’s polarity. The water molecules maintain integrity as molecules‚ however they are considered to be part of the formula of the hydrate. When the hydrate metal salt crystal is heated‚ the attractions to the water are broken by the heat energy and the water escape from the crystal. After heating the salt crystal is called as anhydrous‚ which

Lab Report An enzyme is a protein that speeds up the rates of chemical reactions. They recognize‚ bind‚ and change specific reactants. They do not change so they can catalyze the same reaction again and again. Activation energy is the amount of energy needed in order to begin a chemical reaction. A Catalyst is a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change. Catalysts are substances or a substance that configures another substance
