Questions: Draw arrows indicating the direction of the water movement for each of the thistle tube setups. Molasses in beaker Water in thistle tube Water in beaker Molasses in thistle tube

To address the question about the direction of water movement in the thistle tube setups, we need to consider the principles of osmosis. Osmosis is the movement of water across a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration.

• Molasses in Beaker: Molasses is a concentrated solution with a high solute concentration.
• Water in Thistle Tube: Water is a less concentrated solution with a low solute concentration.

Direction of Water Movement: Water will move from the thistle tube (low solute concentration) into the beaker (high solute concentration) to balance the solute concentrations on both sides of the semipermeable membrane.

• Water in Beaker: Water is a less concentrated solution with a low solute concentration.
• Molasses in Thistle Tube: Molasses is a concentrated solution with a high solute concentration.

Direction of Water Movement: Water will move from the beaker (low solute concentration) into the thistle tube (high solute concentration) to balance the solute concentrations on both sides of the semipermeable membrane.

• Setup 1: Water moves from the thistle tube into the beaker.
• Setup 2: Water moves from the beaker into the thistle tube.

These movements are driven by the osmotic gradient, where water moves towards the higher solute concentration to achieve equilibrium.
