Dialysis tubing is permeable to water molecules but not too sucrose. Three dialysis tubes are filled with various solutions and
placed in the beakers. Tube 1 contains 100% water, Tube 2 contains a 60% sucrose solution, and Tube 3 contains pure water but is submerged in a 60% sucrose solution. Question: Which tube will experience the greatest loss of water? Explain your answer using terms such as (hypotonic, hypertonic, isotonic, solute concentration, water concentration, homeostasis) *
