A. Introduction Title: The effect of reading Shakespeare on reaction time Research Question: Does reading a passage of Shakespeare decrease a person’s reaction time while completing a puzzle? One day in class‚ I was reading an interesting article about how people who read and are exposed to Shakespeare and Wordsworth and other renowned writers have better brain activity‚ attention spans‚ and can have more moments of beneficial self-reflection. In the article‚ scientists and psychologists at Liverpool

rights of minorities within their borders. Although some groups such as the Inuit still feel underrepresented‚ Canada still provides substantial aid and protections for every group and makes cultural acceptance an important consideration when passing legislation. In the wake of the recent US elections‚ I definitely admire the advantages of having representatives that actually consider the rights of all citizens‚ especially when discussing potential legislation. Considering the rights of minorities during

The experiment did not contain any form of reaction mechanism since no chemical identity had been changed. The lab demonstrates the use of chemical molecular behavior to isolate a particular set of molecules. Caffeine had already existed in the leaf itself but needed to be separated from the other chemicals. Caffeine’s chemical structure is relatively similar to the nucleic acid purine in that they use nitrogen and is bicyclic but lacks an alkene‚ amine and an amide. Caffeine has a solubility of

a product. Moles are numbers that are in front of formulae. E.g.‚ 6NaCl‚ 6 is the equation for this formula. A mole would help you balance a skeleton equation‚ and also allows you to calculate how many moles are needed to take part in a chemical reaction. In the laboratory experiment‚ we are investigate the following equation and how they react: HCl(aq)+NaHCO3(s) reacts to produce NaCl(aq)+H2O(I)+CO2(G) (Note*this chemical equation is already balanced in either side of the equation) When HCl(aq)+NaHCO3(s)reacts

Introduction DNA‚ or deoxyribonucleic acid‚ is a double stranded helical structure used to store genetic information in cellular organisms. DNA usually consists of two strands made up of nucleotides‚ each with a backbone of repeating units of phosphate groups and the sugar‚ deoxyribose‚ bonded by phosphodiester linkages. Since the deoxyribose has a specific orientation‚ DNA molecules have directionality so that DNA sequences are read 5’ to 3’. The 5’ end of DNA is characterized by the deoxyribose

MOVIE REPORT: “Percy Jackson: Sea of Monsters” Last Thursday‚ November 14‚ 2013‚ we watched Percy Jackson: Sea of Monsters‚ a movie adaptation from the book entitled the same. Basically‚ the movie is about mythology‚ specifically‚ Greek Mythology. It tackles of the different “gods” of the past‚ their powers‚ origin‚ life‚ and more. Different creatures such as Titans‚ Cyclops‚ and Hecatoncheires were also shown. The movie‚ therefore‚ is truly a great way for people to be entertained while giving
