The image shows a beaker of a sucrose solution (sucrose is represented by the blue circles). The beaker is divided into two sections of equal volume by a membrane which is permeable to sucrose.

Which of the following scenarios is most likely to occur?

• There will be a net movement of the sucrose molecules from the top of the box to bottom of the box.
• There will be a net movement of sucrose molecules from left to right.
• There will be no net movement of sucrose molecules.
• There will be a net movement of sucrose molecules from right to left.
