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…

I was introduced to the field I am interested in from my 9th grade biology class. Prior to the course, I had never taken biology or any science, for that matter, that had captured my attention such as this year-long experience. I was intrigued by the subject and fascinated with all the advances in society that have been made by scientists throughout the years. The possibility of being able to do this in the future kept me engaged and I further pursued this interest by currently taking AP Biology. In addition, I was inspired by the change that scientists can make through research and…
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?…
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.…
One of my most vivid memories from my childhood was the day I received a plastic toy stethoscope from my grandfather. Years later, I realize how it was not only a new plaything, but one that would inspire me to choose my future career path. While medicine is a tough field of study, I know that it is tougher still to toil the earth as my grandfather did in the hot indian summers. At his side after a long day’s work, I would help him at the night clinic he opened for free vaccinations. As I entered high school, I strived to embody such initiative and leadership by running for the Student Council and serving as Class Representative. Taking AP Biology and AP Environmental Science ignited my fascination about how living organisms and cellular systems effortlessly work together, grow, and adapt to their environment,…
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…
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…
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.…
