the reagent in the 1940s. His 1951 paper describing the technique is the most-highly cited paper ever in the scientific literature‚ cited over 200‚000 times. The method combines the reactions of copper ions with the peptide bonds under alkaline conditions (the Biuret test) with the oxidation of aromatic protein residues. The Lowry method is best used with protein concentrations of 0.01–1.0 mg/mL and is based on the reaction of Cu+‚ produced by the oxidation of peptide bonds‚ with Folin–Ciocalteu reagent (a

1. What is the phenomenon of interest and is it clearly stated for the reader? The phenomenon of interest is the experiences of children undergoing stressful testing such as colonoscopies. It is important to obtain information about their experiences in an effort to minimize anxiety. 2. What is the justification for using a qualitative method? A quantitative study cannot be used because information cannot be obtained objectively and results being tested cannot be measured. The qualitative method

Question: investigate the water potential of potato tissue? Introduction All cells require essential materials to ensure their survival. Chemical‚ physical‚ and biological processes are used to move these materials inside of cells. Similar processes move waste materials outside of cells. These processes can be passive‚ occurring as a result of basic physical laws and requiring no outside energy from the cell or they can be active‚ requiring energy expenditure. Since all molecules possess kinetic
