1) Water is a chemical compound of the following substances:
a) Molecular units
b) Molecules
c) Atoms
d) Subatomic particles
ANSWERS: a) Molecular Units.
The graph at the right depicts the various phases of water.
Interstate Phase
The phase is b) Molecules.
Local Phase
The phase is c) Atoms.
Local Ions
The phase is d) Subatomic Particles.
A) Water B) Oxygen C) Hydrogen D) Neutrons
ANSWERS: D) Neutrons.
2) The problem of osmosis is due to the movement of water in a direction opposite the normal movement of water through a membrane when such a membrane is under a
a) large osmotic pressure gradient
b) small osmotic pressure gradient
c) large solute pressure gradient
d) small solute pressure gradient
ANSWERS: b) Small Solute Pressure Gradient
3) The subject of osmosis is often called “the active transport of water by a membrane against a concentration gradient.” This is an accurate statement since there is a net movement of water across the membrane into the cell for two reasons, (1) a chemical potential gradient and (2) osmotic pressure gradient.
a) For why there is a chemical potential gradient, see below:
A) Precipitate.
B) Absorb water.
C) Fluctuate between two states.
D) All of the above
ANSWERS: B) Absorb water.
The graph at the right depicts the two processes which occur during osmosis.
The first process is called “Osmosis by Diffusion”
The second process is called “Osmosis by Convection”
4) To test the concept of osmosis, let us first examine the movement of water in a cell by passive diffusion. The cells in the body contain fluid, hence contain water. Water molecules are present in the water, hence the cell’s water should be like pure water.
A) Not true. Water molecules are present in the cell’s water but they may have been produced by cellular metabolism.
B) True. In the body, there are many types of cells with different chemical and physical properties. There are many different kinds of water molecules.
C) True. Cell water is controlled
