Art has had a great number of different functions throughout its history‚ making its purpose difficult to abstract or quantify to any single concept. This does not imply that the purpose of Art is "vague"‚ but that it has had many unique‚ different reasons for being created. Some of these functions of Art are provided in the following outline. The different purposes of art may be grouped according to those that are non-motivated‚ and those that are motivated (Levi-Strauss). Non-motivated functions

What is art? Can we give a current definition of something so abstractive and unboundless like that? In our modern world‚ everything which is not understandable for the mass audience automatically receives the label "Art" from his creator. Maybe art is something which is not for everyone. You can find lots of popular definitions on the internet‚ on google.com and wikipedia.com‚ also lots of quotes of famous people of art. But what is art for the normal people? The people who don’t know what "linocut"

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

Purpose Determine which kinds of reactions involve electron transfer as the driving force. Background Redox (reduction-oxidation) reactions include all chemical reactions in which atoms have their oxidation state changed. So‚ when a metal and a nonmetal react‚ there is an ionic bond formed‚ which means one of them loses electrons while the other gains them. Since this reaction involves the exchange of electrons it is termed as a redox reaction. The oxidation states in a metal- nonmetal are simple

Introduction: A chemical reaction involves the breaking and forming of bonds in order to create the necessary energy required to cause movement. Each reaction is catalyzed (an increase in rate because of a present catalyst) by a specific enzyme. Enzymes are able to denature proteins‚ meaning that a protein loses its original shape by uncoiling‚ giving it a random‚ unstructured shape. The pineapple plant contains bromelain which‚ because of its unique characteristics‚ keeps gelatin from thickening

In this lab my group and I tested to see how yeast would react to different substances. Yeast is a fungi that releases carbon dioxide which can be used in the process of bread making. During this lab we used sugar‚ warm water‚ cornstarch‚ yeast‚ a gas sensor‚ plastic cylinders‚ and a laptop. The process of this lab was to create cellular respiration‚ which is what cells do to break up sugars into a form that the cell can use as energy. When yeast and a certain substance were combined‚ this substance

All chemical reactions are processed through energy exchanges. Chemical reactions either absorb energy or release energy into their surroundings. In thermodynamics‚ endothermic reactions absorb energy where exothermic reactions release energy. In this experiment‚ we will be observing the chemical reactions that occur when a specific liquid is combined with a specific solid. We will measure the temperature of the liquid before the solid is added. Then we will measure the temperature of the liquid

Demonstration of the Rates of Reaction Between Sulphuric Acid (25mL ±0.5mL) and Magnesium (0.02g ±0.01g) Changing Due to Different Surface Areas By Chania Baldwin Introduction: When sulphuric acid and magnesium are added together‚ magnesium sulphate and hydrogen gas is created. To create such a reaction the atoms must collide with a sufficient amount of energy. Every reaction requires a different amount of energy to create the reaction‚ which is called the activation energy; when there is not enough

by Georg Wittig in 1954‚ the Wittig reaction is a robust organic synthesis method for preparing stereospecific alkenes. In general‚ Wittig reactions involve an aldehyde or ketone and a Wittig reagent (triphenylphosphonium ylide) and result in the formation of an alkene product and triphenylphosphine oxide (side product). Stereospecific alkene products can be synthesized by adjusting the reaction reagents and conditions. In the 60 years since the Wittig reaction was discovered‚ many articles have

CHEM111AC‚ Experiment#9 - Ionic Reactions Discussion/Error Analysis In the first part of this experiment‚ the student was presented with 7 unique and unidentified bottles of solutions labeled A-G and was expected to be able to analyze the 7 solutions through trial and error and mixing them with one another. For solution A: mixing A + B formed a precipitate‚ A + C generated heat‚ A + D gave no reaction‚ A + E gave no reaction‚ A + F gave no reaction‚ A + G formed a precipitate. For solution B: mixing
