molecules of the food coloring equally distributed in the area of the water. Osmosis is a special type of diffusion where only the water molecules move. This happens through a selectively permeable membrane. It allows water and oxygen to move freely across the membrane. Osmosis only has an effect when the cell is in a hypotonic or hypertonic solution. A hypotonic solution is when the salt concentration

How is Osmosis Affected By the Concentration PLANNING Independent Variable The independent variable in this experiment is the thing that I will be changing in the experiment. This is the range of concentrations that have been obtained by diluting the original 1M solution of Sucrose. This is therefore the only thing that is going to be altered as I am investigating how different percentage of water molecules affects the weight of the the potato thus the rate and direction of osmosis.

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

As long-term valuation is assumed‚ risk free rate is set as 30-year treasury rate‚ 5.73%. Cost of debt is 6.72% reflecting Amoco’s credit level. Cost of equity is calculated as 10.63%‚ leading to final WACC at 8.85% (Chart 1). In DCF valuation (Chart 2)‚ long-term growth rate is assumed to be 4%. Change in working capital is calculated as the average of 1997 and 1996 figure and is assumed to be constant for simplicity. Terminal value is valued at $69‚398.1 million and NPV is $51‚525 million.

Diffusion and Osmosis in an egg Low concentration 1.1 Diffusion is the process of molecules spreading from areas of high concentration to areas of low concentration. High concentration 1.1 Osmosis is the diffusion of water molecules through a semi-permeable membrane from the area of low concentration of solute to the area of high concentration of solute. 1.2 Diffusion is important to living cells because it’s the way they take in materials from the environment‚ and they also prevent themselves

| 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%‚

Osmosis Coursework How does the amount of sugar in a water solution affect the process of Osmosis in potatoes? Introduction In this experiment‚ I will be looking to investigate the effect of varying concentration of a sugar solution on the amount of osmotic activity between the solution and a potato chip of a given size. The potato chips were cut to size‚ then added to a water based sugar solution‚ where the variable was the amount of sugar added. The potato chips were cut to size by a potato

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
