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

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

.
The gases will move due to
?
Osmosis

Diffusion
Region A has 40% CH
4
; Region B has 10% CH
4
.
Which direction will the gases move?
?
Left (toward Region A)
?
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?
?
Osmosis
?
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?
?
Region A (inside)
?
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?
?
In
?
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?
?
Shrink
?
Expand
Region A has 6 g/mL of solute; Region B has 1.4 g/mL of solute.
