With the use of criticism‚ this press release is used to satirize how advertisement is degrading to Americans‚ and to mock the ordeal methods used by marketers to sell products to consumers as absurd. By using obvious fictional fads‚ and somewhat surprisingly effective persuasive writing skills‚ this article is humorous and completely irrelevant. However with the correct use of persuasive writing techniques‚ mixed with irrelevant‚ and unrealistic factual information the authors create a humorous

Discussion: We have made four set-ups in two different specimens. Onion and Boat of Moses skin with water‚ 2%‚ 5% and 10% salt (NaCl) Solution. Based on our experiment‚ the result of the set up explains that the presence of the salt solution results in outward diffusion of water and the collapse of the protoplast. In table 1‚ we have observed under the microscope that the onionskin mounted with water has no results of plasmolyzed cell (0%). This time‚ we have repeated the procedure with 2% salt solution

Since the Grignard reagent can easily react with water‚ all glassware including the 25 ml round bottom flask‚ magnetic stir bar‚ 3 and 5 ml conical vial‚ 50 mL Erlenmeyer flask‚ claisen adapter‚ drying tube and 5 glass pasteur pipets were first added to a 250mL beaker and placed in the oven for 30 minutes. After the completion of the thirty minutes‚ 0.150 g of shiny magnesium turnings and a stir bar was first added to the round bottom flask and the claisen adapter along with the drying tube packed

Lab Report Microscopic Study: Investigating Osmosis in Red Blood Cells Lab Report Investigating Osmosis in Red Blood Cells Introduction: The flow of water across a permeable membrane is called osmosis‚ and during this process‚ water moves down its concentration gradient. A solution surrounding a cell is hypertonic if it contains more solute particles than the inside of the cell‚ and the water will move out of the cell into the surrounding hypertonic solution by osmosis. If the solution

Abstract: This report presents the reason why the ocean does not freeze in the winter. Since the ocean consists of salt water‚ an experiment was done to test the effect of freezing on salt water compared to pure water. The experiment was conducted three times in order to obtain accurate results and eliminate errors. In addition to the salt and pure water experiment‚ a variation of this experiment was created to test other options. In the variation experiment the effect of freezing on sugar water

Water Analysis Lab Report Purpose: In this lab we will be testing a number of water samples. These water samples come from various water sources. Each of these water samples will undergo four different tests. The four tests include a pH test‚ a conductivity test‚ a total and phenolphthalein and alkalinity test‚ and a total hardness test. This lab requires comprehension of lab material and techniques learned in prior labs (Kippenhan‚ 2012). Procedure: Each
