be absorbed if they are put in an isotonic solution because of the differences in solute concentration
be absorbed if they are put in an hypotonic solution because of the differences in solute concentrations.

A student is given a dialysis bag filled with starch solution. Dialysis tubing is semipermeable just like a cell membrane. Water can travel across a semipermeable membrane but starch CANNOT. Which model BEST represents the results the student would expect to see if the dialysis bag filled with a starch solution is placed in distilled water for one hour?
Model 1 because the beaker solution is hypertonic, and water would move into
the dialysis bag.
Model 1 because the beaker solution is hypotonic, and water would move into of
the dialysis bag.
Model 2 because the beaker solution is hypertonic, and water would move out
the dialysis bag.
Model 2 because the beaker solution is isotonic, and water would move out of
the dialysis bag.
A student is trying to set up a cell transport lab.
The dialysis tube contains ONLY starch solution, and the water outside of the dialysis tube contains starch indicator (Iodine solution). Dialysis tube works like semi-permeable membrane.
After 20 minutes, the student observes that the inside of the dialysis tube turns black/dark purple. Which statement is correct based on the student's observation?
Water diffused into the dialysis tube because starch molecules were to big to diffuse out. This is an example of diffusion
Water diffused out of the dialysis tube because starch molecules were to big to diffuse in. This is an example of active transport
Water diffused out of the dialysis tube because starch molecules were to big to diffuse out. This is an example of active transport
Water diffused into of the dialysis tube because starch molecules were to big to diffuse out. This is an example active transport.
