that can assist in identification of bacteria are their ecological habitats and more advanced methods such as genetic and molecular composition. Using various techniques one is able to distinguish and ultimately assign then genus and species of the unknown bacteria. Methods: Gram Staining: The Gram stain separates bacteria in two distinct classes and is also useful in distinguishing morphology. Through this technique one is able to identify bacteria as either gram positive or gram negative. The gram-negative

Direction and concentration gradients Bradley Benton ABSTRACT In this experiment‚ we will investigate the effect of solute concentration on osmosis. A semi‐permeable membrane (dialysis tubing) and sucrose will create an osmotic environment similar to that of a cell. Using different concentrations of sucrose (which is unable to cross the membrane) will allow us to examine the net movement of water across the membrane. INTRODUCTION A major determinant of diffusion in a biological system is membrane

experiment was used to examine the hypothesis that: Osmosis is dependent on the concentrations of the substances involved. Diffusion is the passage of solute molecules from an area of high concentration to an area of low concentration (Campbell & Reece‚ 2005). An example is ammonia diffusing throughout a room. A solute is one of two components in a chemical solution. The solute is the substance dissolved in the solution. The solvent‚ the other component‚ is any liquid in which the solute can be

Unknown Microorganism: #5 Report Callie Schalk Microbiology Professor Quave November 24‚ 2015 The unknown microorganism #5 is Pseudomonas aeruginosa. It can survive in a variety of environments and at temperatures found in clinical settings (Murray et al‚ 1999). Clinical setting is referring to temperatures such as those in the hospital environment. P. aeruginosa can also survive in aqueous environments. Pseudomonas aeruginosa is found at several different sources. Nosocomial

THE EFFECT OF CONCENTRATION ON REACTION RATE INTRODUCTION • Concentration is one factor which has an effect o the rate of a chemical reaction. In chemistry we describe concentration in terms of the number of moles of a substance there are in every cubic decimetre (litre) of solution‚ written as moles.dm-3 of M for short. • In this experiment you will find out how increasing the concentration of the acid solution changes the rate of the reaction between dilute hydrochloric acid and magnesium

It is because Auden gives the poem such a title that the whole poem sounds so dramatic and pompous‚ as if it is dedicated to some citizen who have sacrificed so much for the nation. The citizen‚ to my dismay‚ is never named and remains as the unknown one throughout the whole poem. The citizen is referred
