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

“This is a sorry sight” It was always for her. I couldn’t take it‚ I was jealous. She went behind my back and I knew. Her effortless smile‚ glossy‚ silky brown hair and eyes so dark‚ that they can see to the pits of your soul. Lips that have a shine like polished glass. I couldn’t take it. Driving. Witnessing my last glimpses of life. The trees violently stumbling side to side in the gale force winds. The clouds discolouring: from a snow white to a mouldy grey‚ shield encasing its inhabitants

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
