In osmosis, water moves from an area of low solute concentration (high water concentration) to an area of high solute concentration (low water concentration). So, it's the movement of water that helps balance the concentration of solutes on both sides of a semipermeable membrane. My question is when water move from high concentration to low concentration ,it's the movement of water making it balance. So why does it says in definition low solutue concentration going to that high solutue concentration, isn't it make the solute like ion and other molecules going to the higher side and not making it balance. High concentration of water to low concentration water movement is make sense to me But low solute cocentration to high solute concentration part does not make sense at all Please explain how does low concerned ntration solute going to high concentration of solute making balance?

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.
What is the role of lysozyme and a low ionic strength extraction buffer? Select all that apply. Cells absorb water from a low ionic strength extraction buffer, by osmosis, swell and lyse, releasing their contents Lysozyme breaks down bonds in the cellulose cell wall of plants, weakening the structure Cells release water into a low ionic strength extraction buffer by osmosis, shrink and lyse, releasing their contents Lysozyme is an enzyme found in lysosomes in cells Lysozyme breaks down bonds in the peptidoglycan cell wall of bacteria, weakening the structure Lysozyme is an antibiotic found in tears, saliva, human milk and mucus.
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…
8. If two solutions with concentrations of 0.2 M sugar and 0.4 M sugar respectively are separated by a semipermeable membrane, during osmosis, what is the direction of the net flow? a. Sugar molecules from the concentrated to the dilute solution b. Sugar molecules from the dilute to the concentrated solution c. Water molecules from the concentrated to the dilute solution d. Water molecules from the dilute to the concentrated solution
8.Patients who enter the emergency room dehydrated are usually given sterile saline solution intravenously. The solution administered is isotonic to prevent cell damage. What would happen if the solution was hypotonic? Group of answer choices A. Hypotonic solutions have a higher osmotic pressure than that within cells so hemolysis can occur B. Hypotonic solutions have a lower osmotic pressure than that within cells so crenation can occur can occur. C. Hypotonic solutions have a lower osmotic pressure than that within cells so hemolysis can occur. D. Hypotonic solutions have the same osmotic pressure as that within cells so nothing will happen. 9.The solubility of CaCl2 in water is135g/100 ml.

In osmosis, water moves from a _____ concentration to a _____ lower concentration. Select one: higher, lower higher, higher lower, higher lower, lower
For this example of osmosis, there are two concentrations in the solution and the cell. I'm confused as to which one to look at in response to figure out if the cell is hypertonic or hypotonic. Is it in relation to the fructose or the glucose?
Which of the following is false concerning osmosis? Question options: The net movement of water molecules from a region of lower water potential to a region of higher water potential across a semipermeable membrane. Individual molecules of water are in constant flux into and out of cells. The movement of water molecules from a region of higher water potential to a region of lower water potential across a semipermeable membrane. The effects of osmosis vary between cell types.
. DRAW IT An artificial “cell” consisting of an aqueous solutionenclosed in a selectively permeable membrane is immersed ina beaker containing a different solution, the “environment,”as shown in the accompanying diagram. The membrane ispermeable to water and to the simple sugars glucose and fructosebut impermeable to the disaccharide sucrose.(a) Draw solid arrows to indicate the net movement of solutesinto and/or out of the cell.(b) Is the solution outside the cell isotonic, hypotonic, orhypertonic?(c) Draw a dashed arrow to show the net osmosis, if any. (d) Will the artificial cell becomemore flaccid,more turgid,or stay the same?(e) Eventually, willthe two solutionshave the same ordifferent soluteconcentrations?
