Purpose: This is a section that kind of combines introduction, motivation, and some background information. In that respect, in this section, I would like to see brief answers to the following questions: - what did you do in the lab (purpose), and - how did you do it? (The effects that rotation has on motion of geophysical fluids (ocean, atmosphere) was investigated through comparison of motions in a stationary tank (no rotation), and a rotating tank (to simulate rotation of the Earth). This

Coppertone sport spray with an SPF of 30, an expired bottle of Coppertone sport spray with an SPF of 50, a foundation primer produced by Mary Kay with an SPF of 15, and a tinted moisturizer also produced by Mary Kay with an SPF of 20. We were given five petri dishes with nutritional agar that were used to test the correlation between SPF product and yeast strain, as well as sanitized cotton

“Choose your unknown wisely” were the words that our instructor used when we were picking our unknown bacterial microorganism. Each person was paired with another member of the class, and was expected to work as a team to figure out the unknown that was chosen. Using steps and experiments from the Bergey’s Manual, we were suppose to figure out the unknown and how the bacteria we had chosen was classified and characterized. My hypothesis when first starting the test was that this unknown was going

technology advanced medicine since 1750 was the development of penicillin. In 1928, Alexander Fleming whilst studying influenza noticed that mold had developed accidently and completely by chance on a set of culture petri dishes used to grow staphylococci germ. The mold on the petri dishes created a bacteria free circle around itself. He then experimented further and made the mold into some sort of medicine and named the substance penicillin. Fleming wrote down his discovery and published it. However

Bean Beatle Competition Lab RESULTS: In the two control petri dish that consisted of 20 beans with eggs previously on them, the females laid two to three eggs. In the two control petri dish that consisted of 20 beans without eggs previously on them, the females laid to 2 to 6 eggs. The average number of eggs laid on the eggs that already had eggs on them was 1.25 eggs and the standard error was 0.5522. The average number of eggs laid on the eggs that did not already have eggs on them was

washed under running tap water. Then, they were surface sterilized with 0.1% mercuric chloride for a minute and rinsed three times with distilled water. They were further dried on filter paper and put on solidified Potato Dextrose Agar (PDA) in a Petri plate after cutting into small pieces (1 cm). The plates were then put under incubation for 6-8 days at 25±2°C. The mycelial growth of the fungus in the plates were observed for the association of M. phaseolina with the infected roots and was further

the desired destination (Tunneling, 2011). The Opened Systems Interconnect (OSI) Model is a great example of tunneling. The OSI model is divided into seven layers and each layer provides a different task. The below chart is the OSI model (Petri, 2009). In the above chart data is transmitted and received. The user creates the data and now the user wants to send the data to another user or the desired destination. The data has to go through fourteen steps in order to reach its destination

experiment conducted, four sowbugs were placed in a Petri-dish with the options to choose between natural or artificial flavoring found in potatoes and grapes. A combination of instant potatoes and potatoes were used as well as grape jam and grape to figure out the preference of the sowbugs. The potatoes and grapes were thinly diced in order to accommodate similar shape and size to the artificial sample. Placed on opposite ends from each other in the Petri-dish, the sowbugs were then

Abstract Plant-based antimicrobials represent a vast untapped source of medicines and further exploration of plant antimicrobials needs to occur. Antimicrobials of plant origin have enormous therapeutic potential. . Antimicrobials of plant origin have enormous therapeutic potential. They are effective un treatment of infectious disease while simultaneously mitigating many of the side effects that are often associated with synthetic antimicrobials. Present study was executed to mainly investigate
