Controlled Assessment: Osmosis of a Potato [pic] Osmosis: Osmosis is the movement of substances through a partially/semi permeable membrane from an area of high concentration to an area of low concentration to balance of the concentration of the two sides. Biological membranes do allow water to pass through‚ but water will have no net movement unless osmosis takes place. Preliminary Method I have chosen to investigate the factor of the weight of potato strips after set amounts of time

The book “Night” and its topic of the concentration camps of Auschwitz and Buchenwald is very essential to the story. Wiesel describes these camps with great detail and emotion which got my attention and curiosity. With the research I have collected I learned that Auschwitz and Buchenwald were two major concentration camps to the Nazis in Germany that were mainly for either executing prisoners or forcing them to work in a variety of different fields. These two camps were known more as complexes

very being caves in and you breathe one’s last. This is how isolation in concentration camps transforms your tranquil soul into a raving madman. Night‚ a memoir by holocaust survivor and professor‚ Elie Wiesel‚ paints the horrors of isolation and how its knives will carve away your flesh and hope until there’s nothing but a vile corpse. In order to avoid the assured effects of this ‘solitary confinement’ in the concentration camps‚ having loved ones were beneficial because they needed one another

Effects of the Bottleneck and the Founders effect Cecil Smith GS102 Grantham University Online The bottleneck effect happens when something of a great devastation has happened‚ causing a great amount of people to lose their lives and leave behind very few people at the most. The bottleneck effect happens at random and can kill of a whole population and with it can also wipe out the gene pool by doing so. An example of the bottleneck effect would be something like a tsunami‚ or an earthquake‚ which

perceived the next years of their lives much differently than the brutal torture they would endure in their time during the Concentration camps. The formation of these camps were notorious for being one of the most unnerving events in not only WWII‚ but even world history. What was truly intriguing about concentration camps were the ignorance about it’s existence considering concentration camps alone killed nearly a million of their prisoners. The treatment that citizens like Jews had to experience still

Does concentration affect the speed of chemical reactions? Problem: We are proving that “concentration” (the amount of reactants) is one of the things that can affect the speed of chemical reactions. We are also finding a way to keep the lid on the film canister for the longest period of time. We are using vinegar and water as reactants and changing the concentration every time to see the difference between the rates of reactions speed. Materials: - 1 graduated cylinder - 1 film canister

Research Question Does the concentration of substrate (H2O2 (hydrogen peroxide)) have an effect on the activity of the enzyme (catalase)? Theory The higher the substrate concentration the more quickly product is produced (rate of reaction increases) until enzyme saturation is reached at which time more substrate has no further effect. Enzymes such as Catalase are protein molecules which are found in living cells. They are used to speed up specific reactions in the cells. They are all

observe how molarity concentration affects diffusion.The lab was primarily based on osmosis and diffusion. Diffusion is when the movement of molecules from a high concentration that go to a low concentration to a high concentration to eventually reach an equilibrium. Osmosis is when water will diffuse from high water concentration to low water concentration to reach equilibrium. When the solutions are different the lower concentration solute is hypotonic while the higher concentration solute is hypertonic
