Are sustainable: Biomimicry follows Life’s Principles. Life’s Principles instruct us to: build from the bottom up‚ self-assemble‚ optimize rather than maximize‚ use free energy‚ cross-pollinate‚ embrace diversity‚ adapt and evolve‚ use life-friendly materials and processes‚ engage in symbiotic relationships‚ and enhance the bio-sphere. By following the principles life uses‚ you can create products and processes that are well adapted to life on earth. Perform well: In nature‚ if a design strategy

MODULE 2: GENETICS‚ VARIATION AND NATURAL SELECTION SPECIFIC OBJECTIVES & EXPLANATORY NOTES 1. Structure and Roles of Nucleic Acids 1.1 illustrate the structure of RNA and DNA using simple labelled diagrams; The genetic substance found in all organisms called DNA or deoxyribonucleic acid is a kind of nucleic acid. Nucleic acids consist of two long polymers of simpler units‚ called nucleotides; that are composed of three (3) main units as shown below: 1) A pentose sugar (deoxyribose

Acid-Base Titration and Volumetric Analysis The purpose of this experiment is to determine the [NaOH] of a solution by titrating it with standard HCl solution‚ to neutralize a known mass of an unknown acid using the NaOH solution as a standard‚ to determine the moles of NaOH required to neutralize the unknown acid‚ and to calculate the molecular mass of the unknown acid. Procedure: Part A: Standarized 0.10M HCl solution and unknown NaOH solution were poured into two beakers. The burets

13‚ 2013 Saftee Acid In order to complete a shoulder mount for a taxidermy animal the hide must go through several processes. First of which involves removing all of the flesh from the hide‚ once this is complete the hide goes into a solution known as the pickling processes. Once to this stage there are several products that may be used in order to complete a pickled fur. There are three main components to creating a pickling solution; these consist of sulfuric acid‚ non-iodized salt‚

phosphoric acid‚ and 1mL of concentrated sulfuric acid was added to a 250 mL round bottom flask and mixed thoroughly with a magnetic stirrer. A simple distillation set up was installed with a 250mL round bottom flask‚ jack‚ stirrer‚ heating mantle‚ and variac. The solution was heated gently with a small heating mantle to distill the crude product while keeping the vapor temperature around 100C or less. The crude product was collected which contained water‚ 4-methylcyclohexene‚ and trace acid. D

Acid Rain Webquest Name: ________Jacob Rough_________________________ Date: _____3/25/13________ Sulfur dioxide and nitrogen oxides are gases released by the burning of fossil fuels. These gases can react with water and oxygen to form acids. Normally‚ rainwater is slightly acidic. But the additional acid that enters the air when fuels are burned makes it even more acidic. Acid rain can have a harmful effect on fish and other wildlife and upsets the delicate balance

Carboxylic acids are compounds which contain a carboxyl group‚ -COOH group‚ where the -COOH group is attached either to a hydrogen atom or to an alkyl group. One of the example of carboxylic acid is benzoic acid( benzene carboxylic acid) which has a benzene connected to the carboxyl carboxyl group‚ -COOH group. It has a formula of C6H5COOH. The carbon atom of a carboxyl group has a high oxidation state. Therefore‚ that many of the chemical reactions used for their preparation are oxidations. In
