The Effects of pH on Slime Mold Dg Nicole Harris BIOL181 – 059 1 December 2011 The theory that slime mold is attracted to acidic solutions was examined by the slime mold‚ Dg. Dg’s preference of pH was examined by using a variety of pH solutions in a petri dish. The data suggests that the growth of fruiting bodies observed in pH 9 was comparable to that of pH 4.

Introduction! ! The Michelson Interferometer is commonly used to determine the wavelength of light or measure very small distances. It was invented by Albert Abraham Michelson and is commonly used in optical interferometry‚ a branch of physics involving a family of techniques one could use to extract information about waves by superimposing them. ! ! The original application of the Michelson Interferometer was to the famous Michelson-Morley experiment in 1887. Prior to Einstein’s

cheese. Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress

TITLE OF EXPERIMENT 2 : DILUTION 2.1: OBJECTIVES Upon completion of this experiment‚ students should be able to: 1. determine the concentration of coloured solution such as FeCl3 by using dilution and colour differentiating (colorimetric) techniques. 2.2: INTRODUCTION Concentration can be expressed in many different ways such as percentage volume and percentage weight etc. In laboratory‚ normally concentrations were expressed as molarity and normality. Molarity is the

OLD COINS TURN TO GOLD DESIGN: Problem or Research Question: How does zinc effects the color change in a copper penny? Hypothesis: If copper and zinc comes together‚ then it will form brass‚ which gives gold color to copper penny. Variables: There were no variables at this experiment PROCEDURES: Materials: Zinc (SN) filling‚ 3M NaOH solution‚ Copper penny‚ tongs‚ Hot plate‚ 100 ml beaker‚ 250 ml beaker‚ Bunsen burner‚ Water‚ Spoon. Procedure: First‚ we turned on the hot plate.

Lauren Sullivan Plants Imperfections Abstract The purpose of this experiment was to plant different crosses and observe the different phenotypic ratios the plants present. The procedure of this experiment was plant six different crosses and water them correctly so that we could observe the different phenotypes and compare them to Mendel’s proposed ratios. Mendel‚ who had studied peas‚ did a similar experiment and came up with specific ratios that a monohybrid and dihybrid cross should show. His

Investigation Investigate the amount of heat evolved when magnesium reacts with dilute acids. Planning What I am going to do I am going to find out how much heat is given out when magnesium reacts with a variety of dilute acids. In order to make comparisons between the acids‚ I shall use my results to work out how much heat would be given out if 1 mole of magnesium reacted with an excess of each acid. The acids I shall use are hydrochloric acid‚ sulphuric acid‚ nitric acid and ethanoic acid
