Genetic Variation are the differences within individuals in a population. They are what make us genetically different from one another. Genetic variation occur because of mutations in our DNA and recombination. There are multiple types of mutation such as point mutations or chromosome mutations. Point mutations are the most common where only a single DNA nucleotide is affected. Within point mutations are frameshift and substitution. Frameshift mutations are when a base is either added or deleted

October 9‚ 2013 Partner(s): Acetylsalicylic Acid Synthesis Theory. This experiment was carried out to see how the hydroxyl group on the benzene ring in salicylic acid reacts with acetic anhydride to form an ester‚ and to make aspirin. Synthesis of Acetylsalicylic Acid occurs by protonation of carbonyl (C=O) group‚ and a nucleophilic attack of OH on the acetic anhydride. The ferric chloride test and melting point were used to test the purity of the results. A hypothesized recovery rater of above

The Carbon Cycle Poppy Matless Carbon is present in all living organisms. When organisms die‚ the carbon is recycled for future generations. 1. Carbon is released as CO2 via respiration and combustion 2. CO2 is absorbed by producers (grass‚ plants etc) 3. Animals feed off of the plant‚ passing on carbon throughout the food chain‚ losing some carbon as CO2 respiration. 4. When the animal dies‚ it is eaten by decomposers‚ and the carbon returns to the atmosphere 5. If decomposition

Explain what is meant by cultural imperialism Cultural imperialism‚ the practice of promoting the culture or language of one nation in another‚ has emerged in the 1960s along with other terms of radical criticism. It can take various forms‚ such as an attitude‚ a formal policy‚ military action‚ so long as it reinforces cultural hegemony. The term “cultural imperialism” is mainly shaped by the three postcolonial theorists Foucalt‚ Derrida and Said. Within their view‚ cultural imperialism can be

BUFFERS By: Luis P. Bazan‚ RPh.‚ Ph.D. A buffer solution is a solution of: 1. A weak acid or a weak base and 2. The salt of the weak acid or weak base Both must be present! A buffer solution has the ability to resist changes in pH upon the addition of small amounts of either acid or base. Consider an equal molar mixture of CH3COOH and CH3COONa CH3COOH (aq) H+ (aq) + CH3COO- (aq) Adding more acid creates a shift left IF enough acetate ions are present 16.3 Which of the following

There are many reasons why Confederation happened but amongst them there are three that I think are the most important: The Chesapeake Incident‚ The Reciprocity Treaty‚ and The Civil War. Confederation is the uniting of all colonies that were in British North America (Ontario‚ Quebec‚ Nova Scotia‚ and New Brunswick). My first reason is The Reciprocity Treaty. The Treaty is made to eliminate all tariffs for bringing American goods into Canada. The treaty was signed on June 5th 1854 and ended in

To detect an acid‚ the scientists use indicators. Litmus is one indicator. An acid turns blue‚ litmus red. Acids are a group of chemicals with very similar properties. An acid is a sour-tasting substance. Lemons taste sour because they contain citric acid. The sour milk contains lactic acid while the sour taste of vinegar is due to acetic acid. Acetic acid‚ which is an ingredient of vinegar‚ releases only a limited number of ions and is not a strong acid. All these are weak acids. This is the reason
