The Unknown

The objective of this activity was to use the knowledge that we obtained throughout the semester, with the goal to correctly identify two unknown bacteria. Organism number thirteen is Escherichia coli. On the first day, I conducted a gram stain and noticed that the bacteria were pink, meaning that the bacteria are gram negative. I also recognized that the bacteria were rod shaped therefore they were bacillus. I also noticed that the arrangement appeared to be single celled. I also put the…

This section will be a narrative summary of the characteristic of my unknown bacterium that’ll touch base on the morphology, cell well structure, temperature tolerance, antibiotic resistance, physiology and other interesting experiment results. First is going through the morphology of my unknown bacterium; will be talking about the shape, cell wall structure, and other characteristic using the results from tests such as gram staining, simple staining, and spore staining. According to my lab…

The purpose of the whole lab is to use my knowledge of the periodic table to determine the identity and physical properties of each unknown element. To find the unknown elements we looked at the characteristics of the other elements and grouped the ones that were similar and belonged in the same column. By looking at the characteristics of the unknown elements if it seemed to belong in a group with others with a blank we assumed it belonged there. Mendeleev was a scientist who came up with the…

the patient by using the correct antibiotics to kill off the host. In this unknown lab report, techniques and procedures learned in the microbiology laboratory during the semester that was performed to test ones practical understanding of microbiology. The sole purpose of the unknown lab is to demonstrate understanding of the experimental methods and lab techniques learned during…

would be quitting his job at our school, so he planned a very good trip for our 8th grade class. We would be doing a few extra things on our trip than past years, one thing extra was a wreath laying at the Tomb of the Unknown Soldiers. Laying the wreath at the Tomb of the Unknown Soldiers is a great honor, and four…

INTRODUCTION Being able to identify an unknown specimen in microbiology is vital in the laboratory. The goal of this experiment was to isolate bacteria on a nutrient agar (NA) plate to obtain pure colonies of the unknown specimen. This study was done by applying the methods learned in Professor Sprenkles microbiology lab in determining the unknown bacterial growth present with use of pure culture colony morphology, cell morphology and arrangement, and Gram reaction. MATERIALS AND METHODS The…

In the novel Book of Unknown American, Christina Henriquez brought to light multiple stories of immigrants who betted their lives on a future in the United States. Unfortunately, some did not come to fully realize this future. Instead, the immigrants experienced a rude awakening upon arriving in the United States. Although not as grand a scale as to crossing country borders, I also had betted on false dreams. From rumors to blogs, I dreamed college to be a place of great freedom. I could spend…

As Australian Citizens, we remember and honour the Unknown Soldier because he represented all the young men of the British empire who were unfortunately killed during the Great War. During World War I, many unknown soldiers sacrificed their life in either killed during battle, due to bombs, lost when ships sink or many more. The burial of an Unknown Soldier honours the memory and sacrifice of those young men and women who laid down their lives for Australia. His tomb reminds Australians of what…

be inoculated from a mixed broth culture. Multiple tests will be performed in order to eliminate all organisms from the list that do not provide significant results for the identification of the unknown specimens. Journal Entries: April 17, 2018. Today we began the unknown project. I obtained the unknown broth tube #15. I used two Tryptic Soy Agar (TSA) plates in order to make a streak plate. The streak plate is used to separate the two different bacterial organisms that were present in the…

Goals The overall goal of this project was to identify an unknown ionic compound; each group was assigned a small container filled with 5 grams of an unknown ionic compound. In order to be able to identify the unknown compound, we had to do several preliminary tests, cation tests, anion tests, and a reactivity test. Throughout these three weeks, we will identify a compound and its qualities just by looking at it. We also made quantitative and qualitative solutions and tested the compounds' pH,…
