Answer:
glucose: a; moves into sac
albumin: c; does not move
water: b; moves out of sac
NaCl: a; moves into sac
Explanation:
Osmosis is the movement of water molecules through a semi permeable membrane from a region of low solute concentration to a region of high solute concentration
Glucose and NaCl will move into the sac due to the solution in the sac having lower solute concentration.
Water molecules will move out of the sac toward the region with high solute concentration
Albumin will not move because the sac is not permeable to it.
