It prevents contamination from unknown cultures. 3. Does your lab report contain any messages when your inoculation was not complete? What change in the traffic signals indicates an unsuccessful inoculation? Answer: The lab report does not contain any messages about inoculation. There’s only a reference if auto-inoculation was used. The traffic signal light will turn red if the inoculation was unsuccessful. 4. Does you lab report contain any messages when you don’t follow aseptic procedures

Density (Linearized plot) TA: Blue Rex rex Group Members: Billy and Mandy Tuesday; 1200-1350 Abstract: In this lab the density of hand-made clay balls were calculated to understand how scientists model physical effects and to understand logarithmic plots. The hand-made balls ranged from diameters of 2cm to 6cm and were measured with vernier calipers by each member of the group. A total of 6 independent measures of each diameter were taken to establish uncertainty. The clay balls were then

In this TLC lab‚ we explored the relative polarities of Acetylsalicylic Acid‚ Ibuprofen‚ Acetaminophen‚ and Caffeine based on their functional groups. The most overall polar analgesic is considered to be the analgesic that contained the most polar function groups. The amine and amide functional groups are the most polar. In this experiment‚ we found that both these functional groups are found in Caffeine. As a result‚ Caffeine was the most polar out of Acetylsalicylic Acid‚ Ibuprofen‚ Acetaminophen

One of the major results of the Great Awakening was it unified most of the Americans in a common understanding of the Christian faith and life. Education also was a major result of the Awakening. The colleges of Princeton‚ Brown‚ Rutgers‚ and Dartmouth were all founded because of the Awakening. It also led most evangelicals to denounce
