-2 – Hexoxyethanol: 2- Hexoxyethanol is produced by the reaction of ethylene oxide with 1 hexanol. The product is isolated from the reaction mixed by vacuum distillation. Uses for 2 – Hexoxyethanol only pertain to cleaning products.…
Microbiology Final exam Study reference 1. Gram Stain * Verify if bacteria are present or not. * Controls – positive (purple) – S.aureus negative ( red/pink) – E.coli 2.…
To begin this experiment, one should take the sharpie and one plate case, and draw a line straight down the middle. Label one side "phone without hand washing" and the other "phone with hand washing ". On the second plate label it as "control group (hand washing only)". Also, make sure the name of the experimenter and the date is labeled on each of the plates. Turn the Bunsen burner on to a blue flame and put the plates around it on a table. Take the top of the control group plate off and lay it around the Bunsen burner. Then wash the hands used in the experiment using…

The most important fact that should come out of microbiology is the “profound influence” that microorganisms have on the aspects of earth (Cowan, 2012).…

By slowly narrowing down the bacteria by each test, I will be able to conclude the unknown bacteria by its special characteristics.…
There are three types of environments in which cells are located which include isotonic, hypotonic and hypertonic. In an isotonic environment, the amount of water and solute are the same both inside and outside of the cell. As water drifts into the a cell, the same amount flows out creating a balanced environment both inside and outside of the cell. When there is a high level of water on the outside of the cell and a high amount of solute inside the cell, water will be drawn inside of the cell creating a hypotonic solution. The increase in water inside the cell causes the cell to become engorged and erupt. In a hypertonic environment, water will leave the cell, as the amount of water in the cell is higher than that outside of the cell. As a cell looses water in a hypertonic environment it becomes smaller in size and withers. Isotonic environments are preferred by most microbes for the most advantageous growth, although some live in slightly hypotonic solutions. (Alonzo, 2008)…
I have learned so many things this semester that I never thought I would learn. I learned how to measure vital signs, how to identify what kind of food poisoning someone has, what the percentage is for a child of someone with Huntington’s disease, and so much more. I don’t think that I will end up in a biomedical science career, but who knows what the future will bring?…
My long-term goal is to become a forensic pathologist. Through a lot of real world experience in this field, I haves decided that this is the career for me. To become a forensic pathologist, I must become a doctor. Biology has always been a science that is interested me. It will also thoroughly prepare me for medical school and beyond. This academic program will give me opportunities to research during my undergraduate years which will allow me to get the most out of my education. Biology is the perfect major to help me reach my goals and be as successful as I can be in the…
Some common mechanisms by which antimicrobial resistance emerges are incomplete dosing where the bacteria adapts, random mutations that are beneficial are conserved in the species, previous exposure to antibiotics, and some bacteria are naturally transformable; meaning they can absorb the genomic material of other bacteria into their own.…
Growing up, seeing my mother and godmother aspiring to become medical assistants began to enhance my interest in the medical field. Skimming through their textbooks intrigued me on how the human body is extremely complex yet I found it to be so captivating. As time progressed, I became even more intrigued in pursuing a career in the medical field. Thus, when I was accepted to Hillcrest High School’s Pre-Med Program I was elated to see that I was now one step closer. Taking rigorous science courses such as Anatomy, Med-Lab and Microbiology, heightened my enthusiasm as I had finally begun to prepare for my future endeavours. Conducting experiments such as pig dissections, growing bacteria on a petri dish and others intoxicated me with excitement for…
I have always had a curiosity about the complexity of life and how it all works. Ever since I was a young child I have laid awake in bed thinking about how bizarre it is to be alive. This is why I think that biomedical science is the right course for me. I believe it will allow me to further explore topics I find interesting and open doors for me to be able to use my knowledge to improve the lives of others through research and testing. I feel that the skills I have obtained throughout my education will aid me in this course.…
The purpose of this report was to identify an unknown bacterium by applying methods that were previously learned and conducted in microbiology lab class. It is possible to identify a mixed culture by running experiments on the unknown bacteria and taking what we already know and applying it to the results. It helps to slowly eliminate any bacteria that do not correspond with the results of certain tests. An unknown test tube labeled 94 was given to me b my instructor.…
