In the dialysis tube there is 25% sucrose/iodine and same thing 25% sucrose/ iodine in the beaker. The initial mass was 11.59 and the final mass was 11.33. So that means that it’s permeable right? To both water and the sucrose/iodine?

You add a 0.9% NaCl solution to your dialysis bag. What is the osmolarity of this solution?  Answer in mOsm:

17. Muscle. Contractions which move the body depend heavily on diffusion. Why do we have difficulty moving our fingers etc. when they are cold ?

Inside a beaker, dialysis membrane A is filled with a 50% glucose solution and dialysis membrane B is filled with a 50% NaCl solution. Both bags are put into beakers containing 100% water. Which of the following choices is correct? (hint: the dialysis membrane is only permeable to water) a) For both solutions, it is isosmotic, and hypotonic so water flows into the membrane.b) For both solutions, it is isosmotic, and isotonic so there is not net flow of waterc) For both solutions, it is hyposmotic, and hypotonic so water flows into the membraned) For both solutions, it is hyperosmotic, and hypertonic so water flows into the membranee) For both solutions, it is hyposmotic, and hypertonic so water flows out of the membrane

If a blood cell shrinks after being placed in a solution, what can we conclude about the solution?

The net movement of potassium out of a cell (and sodium into a cell) occurs by: secondary active transport simple diffusion facilitated diffusion O primary active transport

Crenation can result from a change in which of the following?   osmotic pressure hydrostatic pressure pH temperature

Which of the following statements is correct? 160 山L 140 KEY 120 Na+ 100 K* 80 CI 60 HCO, 40 Proteins 흐 20 Compartment A Compartment B Compartment B represents the cytosolic fluid Compartment A represents the blood plasma Compartment A represents the intracellular fluid Compartment B represents the extravascular water lon concentration (mmol/L)

Statement 1: The direction of diffusion of a solute across a membrane is determined by its concentration gradient and always moves toward equilibrium. Statement 2: In passive transport, solutes move down the gradient from a region of low concentration to a region of high concentration. A Both statements are true. Both statements are false. C) Statement 1 is true. Statement 2 is false. Statement 1 is false. Statement 2 is true.

The dialysis bag membrane in the figure is permeable to water and to the simple sugars only. The final solute concentration will: • Stay same without change • Reach equilibrium on both sides. • Sucrose concentration will be higher inside the bag. "Environment" 0.01 M sucrose 0.01 M glucose "Cell" • Glucose concentration will be higher inside the bag. 0.03 M sucrose 0.02 M glucose 0,01 M fructose • Fructose concentration will be higher inside the bag.
