Osmosis vs Diffusion

The movement of water across a selectively permeable membrane is
1. Osmosis
2. Diffusion
The movement of gases or solids (solutes) in water or in gases is
1. Osmosis
2. Diffusion
When salt moves from an area of more salt (greater concentration) to less salt (lower concentration) this is
1. Osmosis
2. Diffusion
When water moves out of a selectively permeable membrane to dilute an area of higher salt concentration this is
1. Osmosis
2. Diffusion
Oxygen and Carbon Dioxide transfer between blood and a cell due to
1. Osmosis
2. Diffusion
A red blood cell placed ruptures when placed in pure water due to
1. Osmosis
2. Diffusion
Region A - 10% CO₂; Region B - 30% CO₂.

Which direction will the gases move?
1. Left (toward Region A)
2. Right (toward Region B)
Region A - 10% CO₂; Region B - 30% CO₂.

The gases will move due to
1. Osmosis
2. Diffusion
Region A - 40% CH₄; Region B - 10% CH₄.

Which direction will the gases move?
1. Left (toward Region A)
2. Right (toward Region B)
Region A is 0.35 g/mL; Region B is 2.3 g/mL
The circular membrane is semipermeable, allowing water to move only.

In this example what process is occuring?
1. Osmosis
2. Diffusion
Region A is 0.35 g/mL; Region B is 2.3 g/mL
The circular membrane is semipermeable, allowing water to move only.

Which region has more solute (like salt) in it?
1. Region A (inside)
2. Region B (outside)
Region A is 0.35 g/mL; Region B is 2.3 g/mL
The circular membrane is semipermeable, allowing water to move only.

Will water go into or out of Region A?
1. In
2. Out
Region A is 0.35 g/mL; Region B is 2.3 g/mL
The circular membrane is semipermeable, allowing water to move only.

Since water will move out of Region A. Will the circular membrane shrink or expand?
1. Shrink
2. Expand
Region A is 6 g/mL; Region B is 1.4 g/mL
The circular membrane is semipermeable, allowing water to move only.

Will water go into or out of Region A?
1. In
2. Out
Region A is 6 g/mL; Region B is 1.4 g/mL
The circular membrane is semipermeable, allowing water to move only.

Since water will move out of Region A. Will the circular membrane shrink or expand?
1. Shrink
2. Expand
