Research question: What is the effect of altering the pH of the solution that pieces of apple are placed into on the degree of colour change that occurs when the pieces of cut apple come into contact with atmospheric oxygen‚ as measured by a colour scale? Hypothesis: Altering the pH of solution that pieces of apple are placed into has an effect on the degree of colour change that occurs when they come into contact with atmospheric oxygen. As the pH of solution increases‚ so does the degree

Title: Potato Osmosis Abstract: In this experiment was designed to study the effect of a concentrated solution applied to white and sweet potatoes. The solution’s impact among the potatoes were to be either hypertonic‚ hypotonic‚ or isotonic. The potatoes were first cut into fries with a fry cutter‚ and then weighed after being cut. The white and sweet potatoes’ weights ranged from .005-.015 grams. A total of 18 sugar solutions are to be made over the course of 3 trials. In each trial‚ 6 different

As discussed in the intro‚ the purpose of this lab is to observe principles of homeostasis and osmosis in action. The results of this experiment showed that eggs placed in a 4 M sucrose solution lost mass over time and had the greatest percent difference in mass compared to the eggs in other solutions‚ with the 4 M egg having an average of -25.13% difference in mass. The 0.0 M solution egg only had a 12.28 average percent difference in mass‚ the 0.5 M egg with 10.39%‚ and the 1 M egg with the least

Introduction: The purpose of this lab was to observe passive transport of molecules through diffusion and osmosis. We had to keep close observation on two dialysis bags and explain how we measured the change in weight as diffusion and osmosis occurred throughout the experiment. Cells produce an energy called Kinetic Energy. This causes molecules of the cell to move around and bump into each other. Diffusion is one result of this molecular movement. Diffusion is the passive movement of molecules

Osmosis and diffusion are sometimes mixed up without much thought‚ but they are very different in many ways. Osmosis is a defined as the movement of water through a semipermeable membrane (). The membrane is fully permeable for the small water molecules‚ but is selectively permeable to any substance that is lager that a normal water molecule. One example might be a glucose and water mixture‚ when the solute is put into one side of a U-shaped tube that has a semipermeable membrane between the solvent

Lab Topic: Movement of Materials Across the Cell Membrane—Potato Tuber Cells Introduction: Osmosis is a form of diffusion in which water diffuses through a selectively permeable membrane from a region of high concentration to a region of lower concentration. This form of diffusion takes place when the molecules in high concentration are too large to move through the membrane. Three factors that determine cell membrane permeability are shape‚ size‚ and polarity. For this experiment‚ it must
