Fast Food Noura Adel Al Bader Gust University for Science and Technology Each day one in four Americans visit a fast food restaurant. If you regularly eat fast food it will diminish your health and all consumers should be more aware of that. Every fast food restaurant should put a sign that shows the harmful effect it has on the wellbeing of a human being. Taking care of what you eat should be part of your lifestyle. Fast food advertisements should be strictly controlled, consuming it

CONCLUSION When you put an egg in vinegar, we see that the shell dissolves, but do you ever wonder why? An egg is made mostly out of calcium carbonate which reacts with an ingredient in vinegar, acetic acid. Acetic acid is about 4% of the vinegar and what breaks apart the solid calcium carbonate crystals. The bubbles we see, from the egg, is the carbonate that make carbon dioxide and the other calcium ions float free. This is the equation: CaCO3 (s) + 2 HC2H3O2 (aq) → Ca(C2H3O2)2 (aq) + H2O

Our results from the PCR process were very unexpected, even to the point the control colony had some rather odd outcomes. The goal of this experiment was to choose three colonies from the petri dish that has been exposed to +Amp, and look for any signs of the +Amp resistant gene, blaTEM, within the colonies and decide if this gene does have an impact on bacterial resistance towards the antibiotic. My partner and I decided to utilize a bacterial colony sample that does have blaTEM genes as our control

unknowns the tests I conducted were the Gram Stain Test, Endospore stain test, Urease test, Lactase test, and lastly the MRVP Methyl Red test. The first test conducted was the Gram Stain test. This test was used to determine if the two bacteria were either Gram Negative or Gram Positive. There are four main steps in the gram stain process that all affect the outcome and overall stain and accuracy of the test. The Primary stain is the first step in the gram stain. This process includes staining the

the gram stain. This was done to determine if the bacteria was gram positive or gram negative. After completing the stain and observing the slide through a compound microscope it appeared that the unknown bacteria was purple and rod shaped. At this time it was known the bacteria was a gram positive bacillus. The gram stain was followed with a mixture and then with a simple

and lastly ,a Gelatin test, the unknown bacterium was narrowed down to E. coli. Important conclusions of this experiment were that many tests can be used for identification besides a simple gram stain. Introduction There are several ways to identify unknown bacteria. The first way of identification is gram stains. When a cell is

INTRODUCTION Bacterial diseases is any type of disease caused by bacteria. Bacteria 's are a kind of microorganism, which are tiny forms of life that cannot see by easy only be seen with a microscope. The bacteria that cause disease are called pathogenic bacteria. Bacterial diseases happen when pathogenic bacteria inter the body and begin to reproduce and grow in tissues. Pathogenic bacteria may also emit toxins that damage the body. Common pathogenic bacteria and the types of bacterial diseases

Abstract/Background: This experiment was to observe the interaction of Isopods with abiotic and biotic factors. The Isopods were found in a garden and brought in the the lab. In the lab, each group of students pick a control variable and a dependent variable. Problem: In this experiment, Isopods will be observed to see if paper saturated with the color blue is preferred over paper that is saturated with the color green. Hypothesis: The Isopods will prefer the paper saturated with the color

Microscopes are tools used to enlarge small objects so as they can be studied. Microscopes range from a simple magnifying

The career I have chosen is a microbiologist, some of the main characteristics of the job are working with research teams, and other scientists and technicians. Studying microorganisms like bacteria, viruses, algae, fungi, and several other parasites. They do their work, and studies to learn, or figure out how these organisms live, grow, and interact with their environments. Planning, and conducting complex research projects, you can develop new drugs to combat infectious diseases, and any infection

Music is a huge part of people’s lives because when you cannot find words to describe what is going in life music speaks to you. For instance in Chris Cagle song “My Life’s Been a Country Song” the lyrics “My life’s been a country song; it’s been the words when I couldn’t find ‘em. A friend when I’ve been alone. It’s been the toast to remember, the strength for moving on....” describe how music is always there for people. What exactly is country music? According to the Webster Dictionary, it defined

This study was conducted with a partner, since some parts of the experiment were able to be done simultaneously. One partner prepared a TLC developing jar by pouring a small layer of 4:1:1 propanol/acetic acid/water into a developing jar. A solvent wick was made by wetting a piece of filter with the solvent, and it was placed in the jar. A silica coated TLC plate was obtained, and a spotting line was carefully drawn approximately 1.5 cm from the bottom of the plate using a pencil. Extra care was

The first part of this lab was to get a chromatography, spinach and a quarter. The next step was to draw a line of the chromatography and rub the spinach leaf on it with the quarter. After this, the next step was to place the chromatography paper inside the tube and allow the solvent to rise to the paper. The final step was to remove the paper and mark the spots where the colors had shown up as they would disappear soon after. By doing this lab, it was possible to see all the different accessory

1. Describe the main characteristics of Alcaligenes faecalis. Where is this bacterium naturally found? How large is the genome of Alcaligenes faecalis? Alcaligenes faecalis is an aerobic nonfermentative, oxidase-positive, nonencapsulated, gram-negative rod. It is so named for its ability to produce an alkaline reaction in certain media. Microscopic analyses revealed that the bacteria are located in the esophagus and intestine of the nematodes Steinernema feltiae, S. carpocapsae, and H. bacteriophora

completed in lab, a basic understanding of each type of bacteria was used to create a flow chart that would aid the process of identifying the unknown bacteria within the culture. A gram stain that is performed initially will narrow down the types of tests certain bacteria will and will not respond to. In addition to the gram stain, some of the tests that were used include, a catalase test, an Eosin methylene blue (EMB) agar test, a bile esculin test, and a 6.5% sodium chloride (NaCl) test. If the catalase

the plate for 24 hours. The second step performed was the Gram Stain test. The Gram Stain was used to determine whether the unknown bacterium was gram-positive or gram-negative. First, the unknown sample was smeared onto a slide along with a drop of distilled water. Second, the unknown was air dried and was heat fixed. Third, a series of stains/solution such as crystal violet, iodine, ethanol, and Safranin were used to complete the Gram Stain. During this process each stain/solution was left on

Yousef Hariri Professor Fowler Bio 10 September 24, 2017 Writing Assignment 1 1) A simple way to check whether the cells are bacterial, plant, or animal would be to examine the characteristics of a single cell. A big difference that bacterial cells have that is not found in plant or animal cells is a Nucleoid, which is a certain area whether the genome of the bacteria lies. To differentiate a plant cell from the other two types, one can look for either a cell wall and/or chloroplast, which is what

In experiment three, Gram staining was used to characterize bacteria, either gram positive or gram negative. The Bacillus slide was Gram positive for the results displaying that it had a strong affinity for crystal violet on applying the iodine. The Bacillus slide stained the color of violet because the thicker and richer the layer of the peptidoglycan walls, the more retention of the stain. While the Pseudomonas slide stained the color of red. The Pseudomonas slide was Gram negative due to the lack

enumerating Salmonella spp. in a food sample. 1.2 Hypothesis To achieve a negative results in food sample with the absence of Salmonella spp. 1.3 Introduction The genus Salmonella belong in the family of Enterobacteriaceae is a group of rod-shaped, Gram-negative, and facultative anaerobic bacteria, which grow with or without oxygen. It is also a non-spore forming and a motile or non-motile bacterium with exception of S.gallinarum and S.pullorum. The genus Salmonella consist of two species, S. enterica
