Question
1. Which of the following would be true of a dialysis bag filled with Methylene Blue and placed in pure water for an hour?
Methylene Blue will remain in the bag
Methylene Blue will diffuse out of the bag
The Methylene Blue bag will remain the same weight
Methylene Blue is at a low concentration in the bag
2. The dialysis bag is a stand in for which cell organelle?
Cytoskeleton
Centrioles
Cillia
Cell Membrane
3. Select all of the following that are correct:
Movement across the dialysis tubing wall is driven by concentration gradients
Methelyene Blue can cross the dialysis tubing wall
Starch can cross the dialysis tubing wall
Water can cross the dialysis tubing wall
The dialysis bag restricts movement based on size of the molecule
4. Which bag was demonstrated to gain weight?
Bag 3 with 20% starch solution in beaker of water
Bag 4 with distilled H2O in beaker of starch
Bag 2 with distilled H2O in beaker of methylene blue
Bag 1 with 20% methylene blue solution in the beaker of water
