lens paper‚ bibulous paper‚ regular tap water‚ along with reagents Crystal violet‚ Gram’s Iodine‚ 95% ethyl alcohol‚ and safranin. The first test I conducted was the gram stain. In preparation for the actual gram staining process I had to make a smear. To do this‚ I acquired a clean glass slide. I then placed one drop of water onto the center of the slide. Using the flame from my Bunsen burner I sterilized my loop by passing the malleable end through the flame‚ making sure that the flame went

Calculated gas volume using this distance along with radius of tube tail. o Why is alcohol fermentation needed in yeast to carry out glycolysis In an environment absent of oxygen‚ yeast undergoes alcohol fermentation in order to continue ATP production but also to recycle NAD+ that is needed for glycolysis. Without this recycling‚ glycolysis and therefore cellular respiration cannot proceed and organism

Identification of A Mixed Culture Unknown An experiment such as this one serves the purpose of allowing us‚ the students‚ to apply what we already know about any organism and any laboratory procedure to the difficult task at hand. It is possible to identify a mixed culture by running familiar experiments on the unknown bacteria and taking information already known about specific bacteria and applying it to the results. This helps to slowly eliminate any bacteria that do not correspond with the

At first‚ I thought that Oreos would not have plant cells in them and that we would not be able to extract DNA. However‚ I was surprised to see that there were bands on the gel. On the gel‚ there is one smear that is slightly lighter blue than its surroundings in the sixth lane. This smear is the plant chloroplast gene‚ which barely showed up on the positive control(Lane 2) and lanes 5 and 6. Lane 1 was the ladder‚ which showed DNA fragments of different sizes so we could compare. The third lane
