Woodlice Investigation Introduction: The ecological niche of the woodlice Porcellio scaber. The woodlouse Porcellio scaber is native to Europe but also commonly found in New Zealand. They live in cool‚ dark‚ damp microhabitats such as in rotting wood‚ under rocks‚ in caves and leaf litter. Small insectivorous rodents and birds as well as some spiders feed on woodlice. In the rotting log from which I gathered my specimens there were also millipedes‚ crickets‚ weta and spiders living. Woodlice

artists‚ was pursuing his pet theory--that his own nasal mucus had antibacterial effects--when he left a culture plate smeared with Staphylococcus bacteria on his lab bench while he went on a two-week holiday. When he returned‚ he noticed a clear halo surrounding the yellow-green growth of a mold that had accidentally contaminated the plate. Unknown to him‚ a spore of a rare variant called Penicillium notatum had drifted in from a mycology lab one floor below. Luck would have it that Fleming had

Coccus is a term used to describe a type of morphology that helps us distinguish different kinds of bacteria. The cell’s morphology is only one of the many ways we can differentiate the different species. Looking at these bacterium underneath the microscope is an important step to determine which kind of species it is. All cocci bacteria are not gram positive‚ but this lab will examine only this kind because of their influence in human health. Staphylococcus Aureus is a gram-positive coccus bacterium

CHM 116 Lab Investigations of Buffers I. Purpose The purpose of this experiment was to get an understanding as to how to properly prepare chemical buffers. Also part of this experiment was to gauge the effectiveness of the buffers by measuring their pH levels in various titration solutions‚ using a pH meter. II. Procedure To start our experiment we had to prepare Buffer B‚ which was the .060 M Ammonia/Ammonium solution. Using 3.0 M ammonia‚ we had to calculate

Science February 6 2009 - February 19 2009 Conductor Investigation Calvin Chang 8.2 Stage 1: Planning the Experiment Introduction ! By “electric current”‚ I mean by the rate at which electric charges moves through a circuit‚ the electric charges can either be ions or electrons. They are measured in ammeters and the unit that is measured in is ampere which is the number of charges that passes through per second. There are many factors which would affect the electric current‚ like the voltage of

Who normally conducts the preliminary investigation? What are some of the actions the first responders can take once they arrive at the scene of the crime? Since the preliminary investigation starts when the first emergency call is received‚ it is typically administered by the patrol officers who are first to respond to the scene. First responders can either preserve or contaminate the crime scene‚ which can possibly result in either the success or failure of the prosecution. Accordingly‚ the steps

Science Coursework Trypsin Investigation Aim I am going to prove that temperature effects the rate in which the enzyme Trypsin breaks down milk substrate into amino acids. Investigation "We strongly recommend the use of Vanish Stain Removal Tablets in conjunction with a 900 spin wash at 70°C" This was found on a milk carton of a well-known drinks company‚ Nesquick. The major food group constituent of milk is‚ of course‚ milk. For my Science Investigation‚ I am going to test different temperatures

Franklin 1 Jonathan Franklin Allen Layne Criminal Investigations 18.OCT.2013 Investigations And The Principles A successful crime scene investigation depends deeply on the collection and analysis of various kinds of evidence. Forensic scientists rely on the classification of certain evidence and they have different ways of dealing with it. One major difference is biological and physical. Physical evidence refers to the collection of anything at the crime scene that comes

Aim. The aim of this investigation is to find out how Slaters react to an increase or decrease of the temperature in its surroundings. Hypothesis The speed of the Slaters will increase when the temperature of its environment is increased or decreased from its preferred range‚ so it ensures that they spend less time in unfavorable conditions to avoid desiccation. Method 1. This experiment is done using a water bath to change and control the temperature being trialed. The water bath will have
