These materials are: seeds of specific phenotypes, seed-collecting pan, small envelopes, several wicks, opaque tape, Styrofoam quads, fluorescent light bank, water reservoir, water, water dropper, potting soil mix, fertilized pellets watering tray, petri dish w/ filter paper, and a paint brush. Methods Start by pulling out a four-celled Styrofoam quad, using the opaque tape labeling the quad with the name of the group, the date, and plant name Brassica rapa. Add potting soil to each celled quad

grown in the appropriate substrate, it would release a substance with antibiotic properties. Fleming admitted his discovery of penicillin was an accident. (he accidentally left a Petri dish open) Black and white image of Alexander Fleming in his laboratory. Fleming accidentally discovered penicillin when he left a petri dish open over night. 9. Cotton Gin The cotton gin was invented by Eli Whitney in 1793 and revolutionised the cotton industry in the United States. The machine quickly and easily

Regeneration is a process that regrows and repairs parts of the body that are lost or injured. This process mostly occurs in certain types of animals like worms, starfish and sea cucumbers, but regeneration can occur in every species. The type of regeneration differs, as planaria can regenerate their entire body, as humans can only regenerate cells and certain body organs, such as the liver (Chen et al. 1991). Regeneration is important to the animal because it is involved in functionality, and without

scarlet fever, from infections of the bones, throat, stomach or, brain. Many of us would not be here today had it not been for the discovery of penicillin. In 1928, Alexander Fleming made a chance discovery from an already discarded, contaminated Petri dish. The mold that had contaminated the experiment turned out to contain powerful antibiotic, penicillin. However, though Fleming was credited with the discovery, it was over a decade before someone else turned penicillin into the miracle drug for

The mystery organism was inserted onto the petri dish on February 10, 2015 and took approximately 2 months to development and become visible without the use of a microscope. In the first observation, striations were visible on the brown, rounded seed/spore like organism under 10x magnification. In the second observation, green pigments were visible on the organism and clear, root/hair like structures were visible under 10x magnification. The spores have germinated and has begun to develop into

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

“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
