Microtiter plate

Three agar slants and three nutrient broths were inoculated with Staphylococcus epidermidis using aseptic techniques for transferring samples from broth, agar, and plate cultures. A sterile inoculating loop was used to transfer a loopful of culture from the culture to the sterile media. The lip of the culture tube and inoculated media tube was flamed before and after transfer. The inoculating loop was reserialized after transfer was complete. An agar deep transfer of S. epidermidis was also done…

The search for the legendary lost island known as Atlantis has been grabbing the attention of explorers, historians and philosophers for over 2,000 years. People to this day still argue about its location. Plato, the Greek philosopher, wrote about this ancient civilization in two of his dialogues. Although some argue that this place is fictional, there are scientific and geographical explanations as to why the city would have sunken. Also, there have been relics that were found that suggest they…

loop and sterilized the neck of the tub with heat from before use and before put the cape on. II. To learn how to do a simple streak of an E. coli culture on a nutrient agar plate with one stroke from start to end like a “Z”. III. To learn how to do a complex streak where we grow E. coli culture on the nutrient agar plate for differential the isolate colonies presence. IV. To learn how to know whether the culture is a selective or differential media. The culture bacteria that will be using are…

do to the loop in between streak patterns (on the same plate)? a. After your first streak pattern you should flame the loop again and let it cool. Then you follow the same procedure of lifting the Petri plate, streaking it across the first streak pattern onto the second quadrant of the plate, flame the loop again, etc. 6. How much of the plate do we cover with the primary inoculum? a. We should cover between a quarter and third of the plate in total…

In can be seen from the above that the key to an earthquake-resistant building is strength and flexibility in the materials and structure, and of course the quality of the materials used is important. That is why earthquakes in parts of the world where houses are built in stone, such as North Africa, Nepal and Iran, are so deadly.” An 8.8 magnitude earthquake in Chile killed more than 700 people, whereas in Haiti, a less powerful earthquake measuring 7.0, killed more than 200,000.” (Imagination…

VMS deposits occur in a diversity of shapes ranging from flat lens shaped to large sheet-like sulphide mineral rich bodies (Allen, et al., 2002). The preferred environment for these deposits to form in is submarine near a seafloor opening i.e. black smokers, where hydrothermal fluids escape and precipitate on the ocean bottom (Evans & Moon, 2006). The mineralogy of Kidd Creek VMS deposits often consists out of more than 60 different ore minerals and ore-related gangue minerals, of which 90% or…

movements of our continents is called Continental Drift. This theory is supported by plate tectonics, a relatively new idea that explains the constant movement of Earth's crust. Two-hundred million years ago, our seven continents fitted together, as if part of a puzzle. These continents made up one supercontinent, known as Pangea. When Pangea began to disperse into the current continental positions the process of plate tectonics began. The first to notice the fitting of the continents was…

The Caribbean tectonic plate has a wide variety of height and depth within its borders. While all the land and islands are quite tall, the middle of the plate, that is mostly sea, is much more deep in some areas than others. Around the Yucatan Peninsula, Central America, and all the islands are gradual slopes that gain more depth the further from land-above-sea-level you get, however, from Honduras and Nicaragua to Jamaica, where there should be deeper sea, there is quite a lot of height but…

WARNING! There has been word that the Yellowstone supervolcano is about to blow. A supervolcano is like a regular volcano but the eruption is thousands of time greater than a regular explosion. The last time this volcano erupted was about 174,000 years ago. Yellowstone is still active and another eruption is possible but very unlikely. If it does happen to erupt it could end civilization. There is huge volcano under Yellowstone National Park, which is being watched 24/7. If or when this…

where the North American, Pacific, Eurasian, and Philippine plate meet, also known as plate boundaries. Japan is also located where the Pacific plate and the Philippine plate are subducting. This results in the stress building up where the two plates are subducting. How do plates move? Well, plates move when uneven heating in the mantle creates currents. This current is a convection current, and these currents create different types of plate boundaries. Divergent boundaries split apart from…
