All the reagents and solvents used for synthesizing the title compound were of Analar grade (Merck) and were used as such without further purification. The 2-naphthol derived Mannich base 1-((4-methylpiperazin-1-yl)(phenyl)methyl)naphthalen-2-ol (MPN) was synthesized according to the general procedure described in the literatures [13‚ 14]. The 2-naphthol (4.33 g‚ 0.03 mol) was dissolved in 30ml of ethanol and it was mixed with N-methylpiperizine (3.0 mL‚ 0.03 mol) by continuous stirrer at room temperature

reasons on why the resting heart rate can fluctuate over time. Factors can include things like the temperature of the room we were in‚ or what we ate/ drank for breakfast. Also volume of liquid or chemicals in the cell can impact the heart rate. 2) Is the average resting heart rate for the exercise and non-exercising group different? Provide a physiological explanation for why they are similar or different. In the data that our class collected‚ the average heart rates for the exercising and non-exercising

Introduction Allozyme analysis is a technique which is used in study of genetics because it reveals the genetic variation that exists within a wide range of organisms (Gómez‚ 1998). Allozymes are different forms of an enzyme expressed by alternative alleles on the same gene locus (Micales & Bonde‚ 1995). Analysis of these allozymes can be done by protein electrophoresis. Protein electrophoresis involves the movement of proteins within an electric field with mobility being dependent on factors such

Analysis of Commercial Bleach Lab I. Purpose In this experiment‚ the amount of sodium hypochlorite in a commercial bleach will be determined by reacting it with sodium thiosulfate in the presence of iodide ions and starch. A solution of sodium thiosulfate of known concentration will be added to the bleach using a buret in a titration procedure. The disappearance of the dark blue color of the starch-iodine complex will signal the end point. II. Procedures Pre-Lab Questions 1. What is
