No Sugar No Sugar (1986)‚ a play exploring the treatment of Aboriginal people in the 1930’s‚ was written by Jack Davis‚ an Aboriginal Western Australian who grew up in Yarloop and the Moore River Settlement. No Sugar is told from the point of view of an Aboriginal family who are coerced into living at an Aboriginal reserve because the white people in their community didn’t like them living close to them. The authority at the settlement are very abusive creating conflict between the Millimurra family

| Stage 2 Biology | | Adelaide High School | [Osmosis Practical Report] Abstract: | The purpose of this investigation is to see if the concentration of Sodium chloride (NaCl) solution will affect the mass of the potato cylinder hence the rate of osmosis. This can be done by placing 5‚ identical in length (3cm) but different in weight‚ tubes of potato in 5 different beakers. Each containing an altered NaCl concentration. The concentrations used in this experiment were‚ 0%‚ 2%‚

Rate of Osmosis vs Solute Concentration Introduction: In nature‚ the quest to reach equilibrium‚ or the state of rest or balance due to the equal action of opposing forces (http://www.dictionary.com). Osmosis and diffusion are two ways that cells reach this equilibrium‚ without exerting energy. Due to the unique nature of the phospholipid bilayer‚ small molecules can pass through the semipermeable membrane easily‚ through diffusion (https://www.biologycorner.com). Water‚ however‚ has a slightly more

Effect of osmosis rate on different surface areas‚ depending on different types of water solution An investigation showing the effect of surface area on osmosis rate‚ including some different types of water concentration. Osmosis is a type of passive (not requiring energy) transport of water molecules across partially permeable membrane‚ from an area of high water concentration into area of low water concentration. But how does surface area affect rate of osmosis? Surface area plays important
Premium Osmosis Semipermeable membrane Diffusion
Discussion: Osmosis is a passive process by which water molecules move through a partially permeable membrane from a region of high concentration to a region of low concentration‚ creating an equal amount of molecules from both regions on each side of the membrane. This process is the result of a downhill energy system known as water potential. Water potential is the potential energy of water (per unit volume) that allows it to move from one area to another by osmosis. This system causes the water

Abstract - The experiments done in class served for multiple purposes. It helped identify that diffusion is the shifting of molecules from one part to another that takes no energy‚ and that osmosis is just the flow of water through the cell membrane. The main purpose of the first experiment was to examine the movement of H2O and other materials in living and simulate systems. This was done through the dialysis tubing to mimic the cell membrane and measure the change of mass inside the tube filled

Sugar By Mackenzie Bolland 11P Miss White Sugar‚ a fatty tastes substance that is now in all are foods at a high level. We know that when we eat it‚ its makes are foods taste better‚ but also at the same time. But what do we really know about it. What do we really know about what it does to our body‚ and our lifestyle? Many people argue that’s with the increase sugar intake we are now taking‚ is leading the increase in lifestyle disease’s epidemic. I believe this statement is true‚ with the

DIFFUSION AND OSMOSIS: WHAT’S TO EXPECT? Diffusion and osmosis are very important in biological process. Diffusion is the movement of molecules or ions from a region of their high concentration to a region of their low concentration. Osmosis is the diffusion of water molecules across a semipermeable membrane. To gain a better understanding of diffusion and osmosis‚ we examine multiple experiments to show diffusion and osmosis in animal cell‚ plant cell and synthetic cell. In our first experiment

No Sugar shows us a range of responses adopted by Aboriginal people toward white authority. Discuss. The play No Sugar by Jack Davis which is set in the 1930’s‚ explores and evaluates the way Aborigines were treated unjustly and how they responded to this treatment. Jack Davis presents to us the Milimurra family who are essentially the main characters in the play. They are the minority group fighting against the discriminations laid upon on them by white authorities. Without a doubt‚ Davis positions
