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
Model 2
After 1 hour
●
Model 1 because the starch solution is hypertonic, and water would move into
the dialysis bag.
O Model 1 because the starch solution is hypotonic, and water would move out of
the dialysis bag.
O Model 2 because the starch solution is hypertonic, and water would move into
the dialysis bag.
O
Model 2 because the starch solution is hypotonic, and water would move out of
the dialysis bag.
