  • Sweet Potatoes Osmosis

    Analysis In part one, the varied amounts of surface area and volume had an effect on the diffusion rates of the trials. The greater the ratio was between surface area to volume, the rate of diffusion would increase as well. For example, in cell three the surface area to volume ratio was 11.5 cm which resulted in a diffusion rate of .30 cm/min while cell one had a surface to volume ratio of 3 cm had a diffusion rate of .015 cm/min. This shows that when the surface area and volume are…

  • Osmosis And Hypertonic Solution

    Diffusion is the process in which molecules blend together because of their kinetic energy (Hyperphysics, n.d.). It is a type of transport located in the cell membrane. Diffusion could also be described as the movement of molecules from areas of high concentration to areas of low concentration. The molecules do this because all molecules are constantly moving, so in enough time the molecules will spread evenly. According to figure 1, the cell will make the outside solution the same…

  • Technological Uncertainty Analysis

    5. The techniques using reducing uncertainty In innovation weather it incremental or radical there are some situations organization can’t predict. It always has high risk involvement. When the organization not known the addition information that require for the new innovation product it is uncertainty. There are three types of uncertainty. They are technical uncertainty, market uncertainty and business uncertainty. The following factors help to reduce the uncertainty. 1. technological trajectory…

  • Kitty Genovese Research Paper

    Can someone intentionally walk away from a person in distress on the street? People assume that onlookers nearby will help the distressed person by assisting or phoning emergency services. Yet, most people will not lend a helping hand. For example, in 1964, there was a bizarre crime in New York City; a young woman named Catherine Genovese, commonly called Kitty, was murdered and thirty-eight onlookers witnessed the act and yet nobody came to her assistance or phoned the emergency services.…

  • Lord Of The Flies And Milgram Comparison Essay

    Stanley Milgram was a psychologist professor and in June 1961 he wanted to test people’s obedience to authority. John Darley and Bibb Latane were psychologists who wanted to know why people ignore others cries for help. Both these experiments tie into “Lord of the Flies” by William Goulding in my opinion. And both of the experiments are alike and different in many ways. Milgram wanted to test how well we react to leaders, even if they tell us to do bad things that will hurt others. And Darley…

  • Water Concentration Lab Report

    As stated in the introduction the hypothesis for this experiment was that the solution beginning with the higher concentration of KMnO4 and placed in water with the warmer temperature will diffuse through the artificial membrane quicker than the solutions beginning with the already diluted solutions and placed in water at a cooler temperature. This occurring because all of the solutions are trying to diffuse to where it is less concentrated because they are eager to diffuse down its…

  • Genocide In Horror Movies

    Everybody wants to be a hero, and everyone has what it takes. No, I’m not talking about some ability to grow and become highly skilled or knowledgeable, I’m talking about the ability to obey one’s genes. In horror movies, I find myself constantly wondering why the victim would scream when the killer is right around the corner. Shouldn’t their body, their subconscious, know that it has a better chance of survival if it doesn’t scream? We can thank our species’ progression for that. Over the…
