of blood plasma‚ not of total body water. Bothe are regulated through independent mechanisms in humans and should not be conflated. Some authors have reported three types of dehydration based on serum sodium levels : hypotonic or hyponatremic‚ hypertonic or hypernatremic‚ and isotonic or isometric. Indeed‚ in humans‚ it has been commonly thought that the most commonly

The purpose of this lab was to observe the rate of osmosis and diffusion‚ as well as the effect of molecular size of the particles on this rate. Part I of the lab was a demonstration of osmosis and diffusion‚ that dealt with raisins in different liquid environments‚ each with a different concentration of sugar. Part IV of the lab was using the same idea as the demonstration‚ by putting objects in different concentrations of a substance; in this case elodea leaves in salt water. In both cases‚ the

potential. 2. When the two solutions on either sides of the membrane are equal and no net movement is detected‚ the solutions are isotonic. This means that the solutions have the same concentration of solutes. If two solutions differ in the concentration of solutes that each has‚ the one with more solute is hypertonic. The solution that has less solute is hypotonic. 3. This experiment was performed to measure the osmosis of small molecules through cellulose bag (has the same structure that plant

membrane between the solvent on the other side. The water then moves through the membrane to make the solution more isotonic‚ which means that each side will have an equal amount of water to glucose ratio. With osmosis there are also processes that do not end so well in the concentrations being equal. In hypotonic solutions water flows into a low concentration area‚ in a hypertonic solution water is forced out

When a cell is placed in a hypertonic solution‚ what happens to the cell? shrivels 4. Play the small movie. 5. Hypotonic solutions contains a low concentration of solute when compared to another solution. 6. When a cell is placed in a hypotonic solution‚ what happens to the cell? swells 7.

in both areas are equal and no net movement will occur from one area to another. If two solutions have the same solute concentration‚ the solutions are said to be isotonic. If the solutions differ in concentration‚ the area with the higher solute concentration is hypertonic and the area with the lower solute concentration is hypotonic. Besides osmosis and diffusion‚ molecules and ions can be moved by active transport. This process includes the use of ATP (adenosine tri-phosphate) to drive

depended on the concentration of dissolved solute in the water (in this case the sucrose) and if there are a higher concentration of sucrose in the visking tubing‚ the water in the beaker will move into the visking tubing to make both solution balanced (isotonic). In order for osmosis to occur naturally‚ a semi-permeable membrane is required as a medium. A visking tubing is a semi-permeable membrane‚ therefore it will be used to act as the ‘cell’ for the experiment. This is because the phospholipid bilayer

Labset Three Worksheet 1. What is a carbohydrate profile? Why are they used as a diagnostic or identifying tool? (2) Carbohydrate profiles are specific information on the type and amount of carbohydrate that a product contains. It is used to identify and differentiate two closely related species. 2. What are the carbohydrate profiles of the organisms you tested? (2) The yeast carbohydrate profile came out with glucose and fructose positive and Mannitol negative. The staph epidermidis
