You may have heard the "fact" that snails and slugs "melt" when exposed to salt. A snail's mantle (its outer covering) is a selectively permeable membrane (though not as permeable as a cell membrane). Water can freely pass through the snail's mantle but solutes like salt cannot. The snail's body contains roughly 30% solute and 70% solvent (water). The salt on the surface of the snail's body creates an environment that is 100% salt. i

Information: Osmotic pressure is the pressure that a solvent exerts against a semipermeable membrane, such as a cell membrane. The higher the solute concentration, the lower the osmotic pressure. Red blood cells have an osmotic pressure equal to that of a 0.90% (m/v) solution of sodium chloride and 5.0% (m/v) solution of dextrose. A solution that has a higher concentration that this is called hypertonic; one with a lower concentration is called hypotonic. Osmotic pressure is an important factor affecting cells. Osmoregulation is the homeostasis mechanism of an organism to reach balance in osmotic pressure.Hypertonicity is the presence of a solution that causes cells to shrink.Hypotonicity is the presence of a solution that causes cells to swell.Isotonicity is the presence of a solution that produces no change in cell volume.When a biological cell is in a hypotonic environment, the cell interior accumulates water, water flows across the cell membrane into the cell, causing it to…
A phospholipid bilayer separates two chambers. The chambers both contain the same volume of water. The left chamber contains 150 mM of an unknown solute A. Solute B is dissolved in the right chamber also at a concentration of 150 mM. Therefore, the initial osmolarity is the same (isotonic) between the two chambers. However, after a short time, the volume increases substantially in the right chamber. What is the most likely ranking of permeability for the molecules to cause this change? (greater permeability means that the molecule moves first across the membrane)
The terms below relate to the movement of materials and membranes. Answer the following questions by selecting the correct term.

Observation Before Immersion After 15 minutes of Immersion Starch solution in the cellophane Iodine in the beaker Table 4.1.b Reaction of Starch to lodine Solution Starch in Iodine Solution Table 4.2. Osmosis Solutions Test Tube 1: 0.9% NaCl (Isotonic) Observe Shape of Red Blood Cells Drawing Test Tube 2: Distilled Water (Нурotonic) Test Tube 3: 3% NaCl (Hypertonic) Conclusion
When a person becomes dehydrated the amount of water in extracellular fluids such as blood decreases, causing the solute concentration of these fluids to increase. State weather osmosis results in water entering or leaving cells.
Which of the following is a true statement? Sphingolipids contain 2 hydrophobic, acyl chains Phospholipids contain 3 hydrophobic acyl chains Sphingolipids are completely no-polar, hydrophobic molecules The different types of phospholipids do not have different physical properties when in the membrane
Explain the behavior of water molecules in the isotonic solution.
Which statement best fits the following diagram? The purplish dots are sugar molecules and the blue areas are water molecules. On the left side the water molecwles have a concentration of 99.1% and on the right side the water molecules have concentration of 99.9%. 1) The level of fluid on the left will rise because water will move by osmosis through the membrane. 2) The level of the fluid on the left will fall as water moves to the right by osmosis. 3) The level of the water on the left will rise as a result of sugar molecules diffusing through the membrane. 4) The level of the water on the left will fall as sugar molecules diffuse through the membrane.
