Final Solution

Before The “Final Solution”, is an article that primarily focusses on anti-Semitism in Eastern Europe. Within the first few sentences of the article, the author, William Hagen, demonstrates his belief that German and Polish Jews received the worst treatment. What’s interesting is the author’s differentiation of treatment amongst nations. Upon elaborating upon his views, the author writes about Neville Laski, of the Board of Deputies of British Jews, had gone to Austria, Poland, and Danzig. He…

difference in salt and other particles in solution and in their cell bodies. The salinity and osmolality in an environment triggers a series of regulatory responses in the organism to maintain equilibrium. The equilibrium is essential to its cell’s life and ultimately the life of the organism. The response to maintain such equilibrium is an osmotic regulation, the regulation of the solutes in solution and the cell bodies. When a cell is in an aquatic solution, water, ions, salts, and other…

How does the concentration of salt solution affect the percent change in the mass of potato cells? Hypothesis: If the concentration of salt is increased, then the percent change in the mass of potatoes cells will decrease. Abstract: In this experiment we will be testing how salt concentrations affects potatoes. First, potatoes were peeled and prepped for the experiment; while a salt water solution was being obtained. Potatoes were submerged and left in the solution for two hours, and during…

was 11.09 ounces. We left in a beaker of tap water for 45 minutes and the final weight was 17.98 ounces. The dialysis had a semipermeable membrane and the water soaked through the bag of the syrup. This created a solution of water and syrup 2. The plant takes up water by osmosis and starts to swell. The cell wall prevents it from bursting. Animal cells don’t have a cell wall so the cells will burst in a hypotonic solutions. 3. A wilted plant would have vacuoles are unreplenished. The lack of…

The purpose of the diaper lab was to see if the concentration of solutes in a solution has an effect on the amount of liquid absorbed by a diaper. The experiment tested how well the diaper would retain liquids with a different solute concentration. The hypothesis driving the experiment was if a hypertonic solution is added to a diaper, then the diaper will be less absorbent because the water will be drawn out of the sodium polyacrylate (powder) in the diaper due to osmosis. Sodium polyacrylate…

Standard solution is the solution that is been made by dissolving a precise mass of reactant meaning the starting substance in a chemical reaction, and it is important that the mass is weighed accurately into distinguish volume of water that will be used. This tells us that if the concentration of standard solution is accurate then it can also be used to work the concentration of a different solution that it can also react with. Its concentration is generally given in mol dm-3. Standard solution…

accurate, it should be performed it at least three times, with all the precise measurement of the materials needed, to avoid any kind of error. The control variable would be the solutions; corn syrup and distilled water. The mass of the egg would be tested throughout the experiment. Before placing the egg into the solutions, weigh the mass. After you have the mass recorded, place the eggs into different beakers that each has 150 ml of vinegar filled into it for around two days to remove the…

better blank to use in this experiment. The better blank solution would have been the one with active enzyme because it would cause the spectrophotometer to measure the absorbance of every component in the blank except the substrate, creating a 100% transmittance. This allow the spectrophotometer to read everything that was not in the blank when the actual sample is inserted in because it would “blank” out all the components in the “blank” solution and only read the “uncommon” component. With…

consider supporting his daughter business by using her products in the Triple Plus restaurants. Due to the fact that Wasson helped him when becoming CEO, he decided to present the idea himself to Triple’s purchasing manager, Deidre Hall and left the final decision up to her. Deidre’s Decision…

“I’ll begin at the leisure of those above me, please give me a wink, a nod, a sign of life? I’m sorry, this is student congress after all.” I flashback to the final day of my English class. I look out at the lecture hall am greeted by sea of people. All I can think is that a psychological study done in the early 70’s found that people are more afraid of public speaking then of death. There’s a small chuckle in the room but I don’t hear it. All I can hear is my heart hammering away in my chest,…
