Maura Gongora 12th December‚ 2014 MCB 3020L- Section 018 Unknown #16 Abstract This report contains the background information on gram positive and gram negative bacteria‚ which will aid in understanding the use of specific laboratory experiments to distinguish between the two types of bacteria. Included are the materials and methods used to identify the gram positive and gram negative bacteria and methods which also differentiate between microbes of each group. The implications of the methods of

Rachel Bohnenberger Professor Van Doorn ENVS 150-002 27 April 2015 GMOs Lab Report Introduction As the population of Earth increases exponentially‚ so does the demand for more food. One of the solutions to the question of how more food can be produced is Genetically Modified Organisms‚ or GMOs. There is an ongoing debate about whether or not GMOs are more beneficial or harmful to society. Some of the benefits to GMOs are: growing plants‚ such as corn‚ that are resistant to weeds and pests‚ larger

differences of each is vital to treat a patient correctly. The purpose of this report is to explain the process and steps used to identify a certain microorganism referred to as the unknown. Materials and Methods A test tube with an unknown microorganism will be retrieved. Once the test tube is retrieved‚ a steak for isolation will be completed in order to produce isolated colonies of the organism on an agar plate. The unknown test tube with the bacteria is flame sterilized using a Bunsen burner. Once

audio oscillator to the vertical input of the oscillator. Adjust the sweep and triggering controls until a stable pattern is observed. Positive slope means that triggering can take place only on an increasing voltage‚ even if the value or level is negative. Selection of the appropriate slope and level can help to trigger the sweep at any point like on the input signal. Use the oscilloscope to measure the peak to peak amplitude of the voltage from the audio oscillator. The amplitude of the voltage

illustration of pure bending is given in Fig. 1b‚ where the cantilever beam AB is subjected to a clockwise couple M2 at the free end. There are no shear forces in this beam‚ and the bending moment M is constant throughout its length. The bending moment is negative (M = - M2). The symmetrically loaded simple beam of Fig. 2a is an example of a beam that is partly in pure bending and partly in nonuniform bending‚ as seen from the shear-force and bending-moment diagrams (Figs. 2b and c). The central

Introduction Memory is defined as the faculty by which the mind stores and remembers information(Eysenck & keane‚ 2010). Atkinson and Shiffrin (1968) (Cowan‚ Rouder‚ & Stadler‚ 2000)‚ came up with a model of sensory memory which stated not everything we perceive we process. Craik and Tulving (1975) developed an opposing theory in which they proposed the levels of processing theory‚ stating its not the processing but the type of quality of the processing that is performed‚ that determines the retention

The objective of this macromolecules lab was to identify the presence any of the major macromolecules in various every day food items. The three macromolecules that this lab was carried out for were carbohydrates‚ lipids‚ and proteins. There were five different experiments conducted and each of those experiments had one factor in common‚ they all had the same controls. The controls in this lab activity were already set for the lab activity. The controls were the distilled water and the baking soda

TITLE OF EXPERIMENT 2 : DILUTION 2.1: OBJECTIVES Upon completion of this experiment‚ students should be able to: 1. determine the concentration of coloured solution such as FeCl3 by using dilution and colour differentiating (colorimetric) techniques. 2.2: INTRODUCTION Concentration can be expressed in many different ways such as percentage volume and percentage weight etc. In laboratory‚ normally concentrations were expressed as molarity and normality. Molarity is the

Inorganic Chemistry 1. A subatomic particle with a single positive electrical charge is protons. 2. A subatomic particle with a single negative electrical charge is electrons. 3. A subatomic particle which is electrically neutral is neutrons. 4. The nucleus of an atom is made up of _protons_ and _neutrons. 5. The number of electrons forming a charge cloud around the nucleus is (pick one of the following) greater than; equal to; smaller than the number of protons in the nucleus of the atom.
