“Sorry for the loss” Bullying is a serious issue‚ and it might have severe psychological consequences for the victims. Victims might ‘snap’ at the maximum point of tolerance and do something that they will later regret‚ such as murdering their bullies. The short story “Sorry for the loss” by Bridget Keehan deals with the psychological consequences of bullying and the consequences of victims snapping. The main character of the short story is Evie who is a catholic prison chaplain. Even though she

Diffusion and Osmosis Experiment Methods/Materials: 7.1 Experiment: Rate of Diffusion of Solutes In the initial set up of this experiment I had 2 sets of 3 screw-cap test tubes that had each been half-filled with 5% gelatin and 1-mL of the correct dye (either potassium dichromate‚ aniline blue‚ or Janus green) in each of the test tubes. I labeled the 3 test tubes of set 1 with which die they contained and marked them “5 ˚C”. Then with the other set I did the same exact thing‚ except I labeled

Title: Osmosis in quails’ egg Aim: To observe the effect of different concentrations of sodium chloride on a de-shelled quail’s egg To explain the effects in terms of osmosis Research Questions: Does the different concentrations of sodium chloride on a de-shelled quail’s egg effect the final mass of quail’s eggs that is measured by using electronic weighing balance? Introduction: “If a cell is to perform its functions‚ it must maintain a steady state in the midst of an ever-changing

because the lower the concentration of sugar the greater its water potential and consequently the faster the rate of osmosis. The results show that in each of the five sugar solutions‚ the rate of osmosis decreased with time. This happened because the difference in water potential between the inside and the outside of the beetroot time decreased as the experiment proceeded. Osmosis occurred most in distilled water because this contained the highest water potential when compared with the other beakers

9/17/2013‚ Lois Andersen & Claire Ma “The Power of Osmosis” The purpose of the lab was to discover‚ through osmosis‚ the concentration of sugar water in a potato. First‚ potatoes were cut into strips about 3 centimetres in length and six strips were individually massed. Next‚ the six strips were placed in 6 different Dixie cups‚ labelled A‚ B‚ Q‚ X‚ Y‚ and Z. Each of the Dixie cups were then filled just enough to cover the potato strips‚ with substances that matched the letters of the cups

Introduction In this experiment‚ I measured the impact of two different topical chemicals on growing bacteria over the course of a week. Bleach‚ water‚ hand sanitizer and hand soap were all variables used to observe the effects of the bacteria swabbed from my palm and fingers. Bleach has been the go to product for killing germs and it is because of the similar effects it has with high temperature on the proteins in bacteria. I hypothesized that bleach would be the most efficient way for killing the

shows the higher the concentration of salt the higher the drop in mass. This happened because the potato slices in the 0% and 5% salt concentration became turgid which means it had swollen and became hard. This occurred because of the process called osmosis in which plant cells take up water and they start to swell‚ but the cell wall prevents them from bursting. Evaluation In my opinion the experiment was very successful‚ went according to plan and produced a lot of good results. The timing‚ weighing

concentration of the reactants and products does not change with time. Before this experiment‚ we were educated on how osmosis functions. Osmosis is a process which molecules and water take to usually get through a selectively permeable membrane in order to reach equilibrium. It is a passive transport which requires no ATF and water moves from high to low water concentration. When osmosis is completed‚ there should be an equal concentration o water on both sides of the experiment. We have also learned

Osmosis and Water Potential Year 11 Emary Venter INTRODUCTION: The cell is the basic unit of living things‚ and is made up of multiple organelles. Organelles are membrane bound subdivisions‚ each specialised for a specific function. This experiment looks at the Plasma Membrane‚ which is a semipermeable layer surrounding the cell. It’s primary job is to control what goes in and out of the cell. Molecules can move across this membrane in either an active movement or a passive movement
