the middle. The sticky end of the tape was adhered to nail polish on the leaf. Then by using the tape handle, the nail polish from the leaf was removed carefully and placed on a slide. The same procedure was applied to the second leaf as well. Peels were made from similar locations on each leaf. After by using microscope number оf stоmata per field оf view was counted for ten non-overlapping fields оf view fоr eаch pееl. All data was recorded on the data sheet. By using this formula the all…

Proteus Mirabilis Proteus mirabilis is defined by the slide share website as a disease caused by microbial invasion of the genitourinary track that extends from the renal cortex of the kidney to the urethral meatus. Proteus mirabilis can be laboratory diagnosed by the specimen collection, transported and storage and laboratory methods, but the laboratory methods that would be focused on is specimen collection. It is often the first determine diagnosis and treatment which would give a more…

The gram stain appeared purple so I concluded that bacteria two was gram positive. When observing it under the microscope it appeared to be coccus, in other words circles. They also seemed to be arranged in clusters. I performed the same tests on bacteria two, that I had performed on bacteria one. The first one was the SIM test, my results showed that this bacteria…

figuring out the causative agent in a diseased patient, to knowing the correct microorganism to use when making certain foods and antibiotics. Unknown labs are a key to testing the knowledge a student has gained throughout the course.

the main problem in visualizing neurons was not due to their minuteness, but it was because of the way they are constructed. Neurons are so tightly packed and intertwined together through one another, that when you try to look at them through a microscope, you cannot see anything clearly. With the discovery of the neuroanatomical techniques, the Golgi stain method and the Nissl stain methods; this has allowed neuroscientists to see the complex network of structures differently. It now made it…

Goals E. coli is a type of bacteria that sense and swim towards sugar, amino acids, pyrimidines and electron acceptors. Thus, the goal of this experiment was to determine whether E. coli has a direct motion or random motion when a chemoattractant (glucose) was present. This was done by observing the velocity before and after the chemoattractant and by making Log-Log Plot. Theoretical Chemotaxis refers to the ability of organisms to move in response to the presence of a chemical. The movement…

Conclusion: The the precipitation reactions lab eight out of the fourteen occurring reactions were precipitates. A precipitate means that a solid substance was formed or a substance that is not aqueous was formed. The reactions that did not form a precipitate were DNR, which means that they did not react. At station one barium chloride and potassium nitrate did not react but barium chloride and silver nitrate reacted to form barium nitrate and silver chloride. The precipitate at station one was…

Brains were sectioned at 16 µm in a cryostat, mounted on Super-Frost Plus slides with embedding medium and stored at -80℃. Signals of ISH were detected by digoxigenin (DIG) labeled single strand cRNA probes. The DIG-labeled cRNA probes were transcribed in vitro from cDNAs of rat GR (~0.4 kb) and rat SERT (~0.7 kb) in pGEM-3Zf…
