Lab 1 – Ubiquity of Microbes Bacteria are the most widely distributed organisms in the biosphere. They are found in all different types of soil‚ water and even in the bodies of other living organisms. Every single place that humans have explored on the Earth‚ have shown to contain microbes. Bacteria are living organisms and like all living organisms‚ they require energy and carbon sources in order to metabolize and reproduce. And like all living organisms they respond to changes in their environment

22648860 OBSERVATIONS AND CHARACTERISTICS OF THE SOMBRERO GALAXY (M104/NGC 4594) DOMINIC J. TAN ABSTRACT The Sombrero Galaxy (M104/NGC 4594) is an unbarred spiral galaxy and a suspected member of the galaxy group within the southern regions of the Virgo cluster. It is a nearby galaxy with a very distinctive appearance making it easy to identify. Despite being easily recognisable‚ it is still not completely understood. The exact process involved in its formation is unclear and it is not

Clare Worley 6S 4 - 16 - 18 What Surface in OLV has the most Germs? Introduction I have tested several surfaces in Our Lady of Victory to see which surface has the most germs. I tested ten surfaces and let the petri dishes grow for five days. Over the five days I counted the spores each day and took pictures every other day. It is amazing how things can look and feel clean but they are actually filthy. It is also crazy how many surfaces we touch every day and how one

The sun by definition is the star that is "the central body of the solar system‚ around which the planets revolve and from which they receive light and heat." This self-luminous star is not only the largest object in the solar system containing 99.8 percent of the total mass but is also a fundamental necessity to every human and living thing’s life. The position of the in relationship to the sun‚ Earth determines the time of the year or season. The problem states "assume that at this time of

Microbiology UNKNOWN LAB REPORT Kateryna Petrakova INTRODUCTION Microorganisms cause a great amount of diseases. For healthcare providers it is very important to be aware of what organisms are pathogenic and cause a disease and‚ therefore‚ to find an appropriate treatment. Different microorganisms require various environments in order to replicate and to become dangerous for a person’s health. An integral part of any medical treatment is to be able to recognize and

Connor Lauffenburger 3/17/13 pGlo Transformation Lab Report I Introduction The purpose of this experiment was to show the genetic transformation of E. coli bacteria with a plasmid that codes for Green Fluorescent Protein (GFP) and contains a gene regulatory system that confers ampicillin resistance. A plasmid is a genetic structure in a cell that can replicate independently of chromosomes. In this lab‚ the Green Fluorescent Protein‚ which is typically found in the bioluminescent jellyfish Aequorea

Introduction: Antimicrobial agents are chemicals that are used against bacteria. There are many such agents available. Because there are many different situations where bacterial control is important‚ no antimicrobial agent is effective in all situations. For example‚ you wouldn’t use the same compound to fight an ear infection as you would use to sterilize surfaces in an Operating room. The situations are completely different. In one case‚ you are trying to assist the body to fight off an internal

Hand Washing Experiment Outline I. Introduction a. This lab was conducted in order to understand and apply the scientific method. The experiment tested the effectiveness of reducing microorganism (bacteria) with the use of various hand soaps. b. Hypothesis: If the Harris Teeter Foaming Hand Soap is more effective in reducing bacterial growth than the Soft Soap hand soap‚ then there will be less bacterial/microorganism growth present on the agar plate for the Harris Teeter Foaming
