What Is Microbiology? Microbiology is the study (logy) of very small (micro) living (bio) things. Microbiology is the study of microorganisms. These "bugs" include: bacteria (that’s the Latin plural for bacterium); viruses (that’s the non-Latin plural for virus - virii sounds weird‚ so I don’t say it); and‚ fungi (that’s the Latin plural for fungus - which by now you have guessed‚ or already knew‚ and may not be all that interested to know‚ anyway). Microbiology is actually made up of several

per gram of substance‚ the greater the temperature change. The relationship between the heat added‚ the mass of a substance‚ and the temperature change it undergoes is known as specific heat. Specific heat is defined as the amount of energy necessary to produce a temperature change of 1°C per gram of substance. The specific heats of different substances vary‚ and therefore this quantity may be useful in identifying an unknown. The measurement of heat changes is called calorimetry. In this lab activity

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

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

the product can be stained with the gram staining. Gram staining is the method of differentiating bacteria into 2 large groups of Gram-positive bacteria and Gram-negative bacteria based on their cell wall. Most of the bacteria or yeast in the starter cultures used are Gram-positive. Gram staining requires 4 types of solutions used in the procedure: crystal violet‚ mordant‚ alcohol and safranin. The Gram-positive microbes will have blue stain while Gram-negative stains pink after the procedure. Methylene

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
