Lab 11 Methodology By using aseptic‚ a little cultured bacteria was inoculated on the TSA agar. A quadric streak was making. Inoculation loop was heated and keep it cold for a while before the next quadratic streak. Six agar plates were observed for 24 hour at temperature of 30ºC. Choose one from the dense colony and make a sub-culture on the new agar plate. The step was repeated to get a single colony‚ which is pure colony. a) Sequestration of bacteria from fish organs Methodology

Plate boundaries Plate Boundaries is a theory of the global movement over a period of time. There are three main types of plate boundaries they are‚ transform boundaries‚ convergent boundaries‚ and divergent boundaries. Transform boundaries are where two plates are sliding past each other. These areas are also known as faults. Most transform boundaries are found on the ocean floor‚ a few however are found on land. Since these boundaries do not crunch together they to not tear or break

Plate tectonics Intro: The word tectonic represents the meaning of plates and boundaries. As an example of activity is an earthquake‚ which is caused by two plates like the Eurasian and pacific plate pushing towards each other‚ pushing the land upwards causing a mountain as well as an earthquake. The plates are pieces of land that make up the outer crust‚ these could move together‚ move apart or move alongside each other resulting in mountains‚ volcanoes and earthquakes‚ this happens deep

sterilizing it with 70% ethanol. Then trypticase soy agar (TSA) was poured into six groups of 60 Petri dishes (See Appendix 1). The dishes were labeled based on the antibiotic used and were left to dry and solidify at room temperature. After an hour‚ the dishes were placed in a refrigerator at three degrees Celsius. If there was visible condensation on the agar plate‚ they were flipped to avoid the contact of heat that drove the moisture out of the agar dishes. The contents of the broth culture of E.

Plate Tectonics Paper Michelle Tillman GLG/220 1/12/15 Jessica Terrien Dunn First and most important hazard is the ground actually shaking. This causes building to be damaged or the ground/foundation to settle different than it was. If the soil is liquefied then the building can actually sink into the ground. This can make the buildings also tip and lean. Los Angeles was built on a myriad of transform faults that include Santa Monica fault‚ the San Fernando fault‚ and Northridge/Santa Barbara fault

4 sterile cotton swab‚ sterile water in test tube‚ 4 agar plates and 2 blood agar plates‚ wax pencil and labels. Procedure: Appropriately label the cover of each plate as indicated in lab. 1. Determine 2 sampling sources‚ one from your body and one from the surrounding environment. 2. For the first agar plate‚ for sampling from air‚ remove the lids from the plate and allow it to sit uncovered for 15 minutes. 1. For second agar plate‚ open the “stick” end of the sterile cotton swabs to avoid

facilitates the handling of large numbers of bacterial clones for classification on a variety of media. METHODS Replica plating. A frequent chore in bacteriological work is the transfer of isolates from one substrate to other selective or indicator agar media. In place of an inoculating needle‚ one might imagine a device consisting of many needle tips in fixed array‚ so that one operation would substitute for repeated transfers with a single needle. The requirements of this design are met by pile

In this lab you will test the idea that microbes are ubiquitous or present everywhere at all times. Materials One Triptic Soy Agar (TSA) plate per student One sterile swab Procedure 1. Decide on an area to test for the ubiquity of microbes. List your area on the white board in front of the classroom. 2. Obtain one TSA plate and label it on the bottom (side with the agar) with your name‚ class section and the surface you will sample. 3. Obtain one sterile swab. 4. To obtain a sample‚ roll the sterile
