Stain

laboratory four through simple staining. Single staining consists of a single dye which informs only about cell shape and size, rather than differences between cell components. Through the simple stain, it was found that the unknown is a staphylococcus microorganism which is spherical and in clusters. The gram stain was performed in laboratory six and this helped determine whether the…

12 August 2015 In the chapter called “What Do You Do With The Kid Who Can’t Read?”, we find out that Faunia absolutely loves crows and that she almost considers them family. Faunia says that she is a crow in a human’s body and she hopes that she will turn back into a crow after she dies. This obsession with the birds reveals several things about Faunia and the story as a whole. First off, Faunia says that most people see the crows as ugly scavengers, which means she also implies that people see…

Albert Einstein once said “The definition of insanity is doing the same thing over and over again and expecting different results.”In the story the narrator tells us how he watches an old man in his sleep planning to kill him when his eye is open.The narrator kills the old man and hides his dead body under some floor boards.The police come and the man feels guilt and admits his deed. The narrator isn’t crazy because he says he isn’t crazy and he planned the murder.Nevertheless the narrator…

organisms. Under microscopic examination for my unknown 16 broth, it appears to be a coccus shape and a gram positive. Gram staining can determine cell morphology, size, and arrangement. In a positive gram stain, a primary stain called crystal violet is used to stain the cell. For every new stain, mordant, decolorizing agent, and counterstain, it must be rinsed with distilled water. Then mordant is added, creating a crystal violet-iodine complex. The slide’s then rinsed with 95% ethanol until it…

observed. There were multiple tiny whittish isolated colonies present, all of which showed the same growth pattern. Three colonies were chosen at random and Gram stains were performed on each (procedure for the Gram stain was used according to laboratory manual ex. 9). Each of the three Gram stains showed positive rods. After the Gram stain was determined, I began to do more research on microorganisms that had that identification and narrowing down all the possible tests to continue for…

identity is not as hard at all. Just as long as someone knows what he or she is doing these will go smoothly. First, we have to grow them in differential medium for culture separation. Then after 48 hours of incubation we started to identify the gram stain. From that, different tests were performed to be able to find the specific identity of bacteria further tests will be explained in each specific method…

back with water. Make sure that forget about cleaning soap residue exists. Make use of the towels to dry the ground and dry sponges to recover its shine. For those who have a persistent stain that simply will not disappear regardless of how that which you do. Then use a stain remover like a latter. Don't use a stain remover regularly because this may cause permanent injury to your marble floors. Again, just make certain the items you utilize don't contain acidity as this can seriously harm your…

As homes with larger kitchens have become more and more accepted, many homes now have a kitchen/dining area with overhang counters.

for you. Laser Teeth Whitening Laser whitening uses peroxide and a laser to remove stains from food and yellow discoloration from smoking. It is much more effective than products you use at home because the peroxide is stronger and using the laser makes the treatment more effective. When laser whitening works, you can see results after a single…

Identifying a bacteria based off of physical characteristics is almost impossible due to the commonality of shapes and physical features. Because of this, a wide range of biochemical tests were preformed in order to better identify the bacteria. Being able to identify an unknown was the most interesting part of the microbiology lab this semester, as well as, being able to preform the various tests. Proper aseptic technique was used throughout the semester and followed during all biochemical…
