The total protein content was estimated as proposed by Lowry et al. A bovine serum albumin stock solution (1mg/ml) was prepared in sodium hydroxide (1N). Five different concentrations (0.2‚ 0.4‚ 0.6‚ 0.8‚ 1 ml) of the prepared solution were taken in different test tubes. In another set of test tubes‚ 0.1 and 0.2 ml of the extract were taken. In each test tube‚ the volume was made up to 1 ml‚ followed by addition of the prepared alkaline solution (5 ml) at room temperature. The solutions were left

Water Wheel Work‚ Power‚ and Efficiency Pre-Lab Preparation: Purpose: The purpose of this lab was to create an efficient water wheel that would produce a productive time in lifting the cup of nuts and bolts that was attached to the pipe used in rotating out water wheel. The more efficient our wheel was the better the time we would have in lifting our cup. We were then able to observe the work that was needed to turn the axel‚ the time that is taken to bring the cup of washers to the axel‚ and

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
