cell reaction to an isotonic‚ hypotonic‚ or hypertonic solution. Another objective was to understand the nuances of simple diffusion‚ facilitated diffusion‚ and active transport and to explicate the characteristics affecting the rates of diffusion. The next objective was to be able to explicate the partition coefficient and its influence on hemolysis. The final objective was to properly use a pipette (Spilios‚ 2015). Hemolysis occurred despite the red blood cells being in isotonic solution (0.3 M)

sample is dark and smaller. Result : 1) RBC’S when placed in distant water solution with a lower concentration level hypotonic the cell will swell and burst . 2)RBC’S when placed in a Nacl solution with the same concentration level isotonic the cell will remain the same no change in shape or size . 3)RBC’S when placed in Nacl solution with higher concentration level hypertonic the cell will shrink and

Throughout time many athletic players drink sport drinks like gatorade or powerade but the question is when should we drink sport drinks or water. Your body needs water to maintain performance. Water is composed of two hydrogen and one oxygen atom. For your body to maintain athletic performance it must have oxygen in the muscles (which water contains). When exercising we burn carbohydrates. When we lose these carbohydrates they need to be replaced. There are many alternatives to replace carbohydrates

A hypotonic solution would have a high water potential and a low solute potential. An isotonic solution would have equal solute and water potentials. Water

in different carbohydrate solutions then there will be a percent change in mass. The carrots have large vacuoles that hold water‚ this allows the mass to increase when the hypertonic solution is .2 M and 0 M‚ around .4 M the mass stays near the same because it is an isotonic solution‚ lastly the mass decreased when the hypotonic solution is .6 M and above. The experiment was developed with 6 plastic cups containing varying

This is due to the molecular collisions speeding up the experiment in the time period given because of the Soule molecules found within the given volume. This experiment can also refer to hypo‚ hyper and isotonic due to the two solutions being separated by the dialysis tubing (which acts as a semipermeable membrane) and diffusing from

vital for the diffusion of water and maintaining homeostasis. Homeostasis is the ability to maintain equilibrium and keep the organism alive. For example‚ if a cell is placed in a hypotonic solution there is more water inside the cell that outside which will cause water to diffuse out in attempt to reach equilibrium. Hypertonic solutions are when there is more water outside
