When selecting specific bacteria, I looked for the best combination of variation and choosing across all five of my plates for both agars. Through using morphological observation I was able to determine different bacteria such as colonies that are irregular and circular continuing

Chemistry Exploration Topic: determining the activation energy of a chemical reaction Research Question: What effect does temperature of the chemical reaction have on the activation energy ? ICT: Microsoft Word Autograph Microsoft Excel Introduction This experiment is designed to help in estimating the activation energy of the rate-limiting step in the acid catalyzed reaction of acetone with iodine. This is achieved by measuring the reaction rates at different reaction temperatures over

cotton swab and a petri dish and searching for a collection site in the Biology Department that would have bacteria. The unknown sample was collected at a recycling bin in Biology Building East. We swabbed the recycling bin using the sterile cotton swab and gently streaked the swab across the surface of the petri dish and immediately covered it with the lid. The petri dish was then placed in an incubator at 37C for two days. Two other petri dishes were obtained air and skin. The air petri dish lid was

E. Discussion: In order to synthesize the polymer, Nylon 6,10, we had to complete a few steps to create the chemical reaction that combined sebacoyl chloride and hexamethylenediamine. First we measured the mass of the two graduated cylinders when they were empty, and measured it again after they were filled with sebacoyl chloride and hexamethylenediamine. We did this in order to find the measurements of the reactants. When we measured the graduated cylinder when they were emptied, one weighed at

Spearman (general intelligence), Gardner (multiple intelligence) and Goleman (emotional intelligence) have all looked into further research regarding intelligence, where 3 different theories were formed regarding what intelligence

Human beings have strived to uncover fundamental truths about human nature for centuries – even millennia – but humor itself is still yet to be pinpointed. Henri Bergson is only one of many who has attempted this feat, and his essay Laughter: an essay on the meaning of the comic from 1911 breaks
