NAME: PRAJWAL BHARADWAJ Ampicillin‚ Vancomycin‚ and Tetracycline Effectiveness on Gram Positive and Gram Negative Bacteria. INTRODUCTION: Bacteria are microbial organisms which are present in various environments. Many bacteria are good and help humans synthesize materials and assist in biological processes‚ such as digestion. However‚ some bacteria can cause harmful diseases. When harmful bacteria infects the body‚ people take antibiotics in order to suppress bacteria. Different antibiotics have

Gram Stain: The important part of this experiment is being able to determine a bacterium based on its cell wall structure. It also helps indentify if the unknown organism is a Gram positive or Gram negative. This is the initial step that must be taken before any other lab procedure may continue on to ensure the purity is present‚ the arrangement of the cells‚ and the shape the cell has. The staining of the cell starts off with using the primary stain‚ Crystal Violet which is a purple color‚ to begin

Introduction: The gram stain is one of several laboratory procedures that can be used to narrow down the identities of unknown bacteria. Bacteria have three different shapes; cocci‚ bacilli‚ and spirilla. Since bacteria pretty much have the same reflective index as water‚ a bacteria cell must be dyed so that these shapes can be seen. Materials: Petri dish Dropper Cleansing solution Slides Bibulous paper Inoculation loop Crystal violet dye‚ Iodine Acetone Safranin Water from the sink

Verbal bullying can affect someone’s psychological and emotional life and cause depression‚ low self-esteem etc. Gesture bullying contains treating messages through non-verbal frightening gestures which can result with anger‚ powerless and exhaust. Physical bullying affects victim and the bully as well. It is presented by hitting‚ pushing‚ slapping‚ tripping etc. The exclusion is isolating the person in work activities

Introduction:The objective throughout the gram staining experiment was to classify bacteria through their chemical nature as well as the physical structure of their cell walls. Through this experiment one would be able to observe either a thick or thin layer of peptidoglycan by the appearance of the bacteria staining either gram-positive blue-purple or gram-negative pink. Question: Is there a subsequent effect of the bacteria when decolorizing with alcohol? Hypothesis: If there is either a removal

where and how health care related resources should be spent‚ “cost-per-QALY” is one of them that have received considerate academic attention over the last few decades (Alder‚ 2006). As such‚ it is key to investigate if this particular criteria has a legitimate weight in this allocation decision process‚ and if so‚ within which boundaries. To do so‚ in a first section I will briefly define

change is not seen as so urgent as it is stressed when it is viewed in a small span of time but when this span is enlarged‚ the cost of remedying climate change greatly increases. As CO2 increases‚ the damage it will do to the world increases as well which will also lead to money needed to fix whatever damages might occur. In order to pay for an amount that will be incurred over time‚ economists use the discount rate so they can account for a future value. The reason this rate is used is because an amount

The question being addressed in this lab is which ingredient will produce the most bubbles? If baking powder‚ baking soda‚ and salt are added to different test tubes of sugar water‚ then baking soda will have the most effect on the rate of fermentation (create the most bubbles). This hypothesis is rejected. Based off of data‚ the hypothesis was rejected. The ingredient that produced the most bubbles was baking powder. In the experiment finishing at 20 min.‚ the control had 2.5 cm of bubbles produced

Which pressure groups are the most powerful? Some pressure groups are clearly more powerful than others. Some succeed while others fail. But what does ‘success’ mean? How can we weigh up pressure-group power or influence? These are difficult questions because ‘success’ may be measured in different ways. Success may mean: * Affecting government policy – policy-making power. * Pushing an issue up the political agenda – agenda-setting power. * Changing people’s values‚ perceptions and

difference between a gram positive bacteria and gram negative bacteria is the differences in cell wall composition. Prokaryotes known as eubacteria have three basic forms: rods‚ cocci and spiral. The bacterial cell wall is the single most important contributor to cell shape. In addition to shape of cell wall‚ presence or absence of flagellum‚ and if present‚ positions of flagellum‚ the eubacteria can be classified according to Gram Stain. First and foremost‚ gram positive bacteria are
