Discussion A negative relationship between the RBC concentration and LIM voltage is observed, when more blood is added to the isotonic saline solution, blood concentration increased, therefore the protein concentration become greater in the solution. The greater concentration of protein in the solution the more light is scattered. The intensity of the scattered light increased, resulted in a lower voltage was detected by the LIM device. Thus resulted in a trend of decreasing voltage with an increasing

The effect of osmosis on artificial cells with different concentrations of sucrose Alex McRae Biology 120-902 Grand Valley State University 1 Campus Drive Allendale, MI 49401 mcraeal@mail.gvsu.edu Abstract In this study, we tested the validity of osmosis in artificial animal cells. Osmosis is the diffusion of free water across a membrane. The purpose of the study was to calculate the rate of osmosis in artificial cells containing different

The cell membrane controls the movement of substances in and out of the cell. Oxygen and food move inside the cell through the membrane in the process of diffusion. Diffusion occurs when cells move from an area of high concentration to an area of low concentration. Osmosis is a type of diffusion; it is a diffusion of water through the cell membrane. Osmosis takes place when water particles move from a more concentrated area to a less concentrated area. For this process to take place there must be

Abstract: The purpose to this experiment was to study the effect of osmosis in de-shelled chicken eggs in different percentages of sucrose solutions. Osmosis is the process, in which, water moves across a differentially permeable membrane. The eggs were soaked in vinegar to remove the outside hard shell but still leave the egg in its membrane. By placing the six de-shelled in different sucrose solutions, we tested the rate of osmosis. The eggs were placed in the solutions for an hour and weighed

INTRODUCTION Osmosis is the “diffusion of water across a selectively permeable membrane” (Raven et al. G-16). In this experiment, dialysis tubing was used to mimic the selectively permeable membrane to show what osmosis does when placed in different solute concentrations. We filled the dialysis tubes with different percentages of solute and placed them in beakers full of another percentage of solute. Through this experiment, I saw what happens when the tube becomes hypertonic, hypotonic, and isotonic

The original purpose of this investigation was to determine if different sodium solutions and Staminade would be better than water in aiding the rehydration of hypertonic cells and reversing the effects of Hypernatremia. After conducting research it was discovered that Staminade was the most effective in reversing the effects of Hypernatremia and rehydrating the cell. This investigation followed the hypothesis that if a cell was hypertonic, then sodium solutions of different concentrations and Staminade

Cell function changes depending on the types of fluid loss. There are three types of fluid loss: Isotonic fluid, hypotonic fluid, and hypertonic fluid. The isotonic fluid loss means that the water loss is in the same proportion to the electrolytes. Water and electrolytes are lost from extracellular compartment first. Then, they are moved out of the cells to replace the loss in extracellular fluid. Since there is no osmotic pressure change, there is no shrinkage or swelling of the cells, but only

Osmosis in a Decalcified Egg to Determine the Glucose Content of an Egg Tovah King C62 7/5/2017 Abstract: Diffusion is the transfer of molecules from an area that has a higher concentration to an area that has a lower concentration. Osmosis is the diffusion of water. The purpose of this experiment was to study the process of osmosis. In order to test osmosis, eggs that had been soaking in vinegar were taken and placed in four beakers of solution with different levels of glucose

If I am to figure out the estimated concentration of sucrose found naturally inside the potato using osmosis, then there will be a change in the mass of the potato because it will either be hypotonic or hypertonic to the cell, as it will affect the size of the cell along with in. The 0 M, 0.2 M, and 0.4 M solutions were are hypotonic to the cell. Hence, they contained less solute than the potato itself. Therefore, the potato cell increased in mass because water was moving into the cell. It was more
