Osmosis vs Diffusion

1 / 20

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 ruptures when placed in pure water due to
1. Osmosis
2. Diffusion
Region A has 10% CO₂; Region B has 30% CO₂.

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

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

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

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

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

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

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

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

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

1. toward A
2. toward D
3. neither
If the above boundaries only allow OSMOSIS, which direction will water go between G and H?
1. toward A
2. toward D
3. neither
