In osmosis, when will there be changes in volume of the two compartments separated by a selectively permeable membrane?
| A. |
When particles in solution are prevented from crossing the membrane (nonpenetrating solutes). |
|
| B. |
When the water concentrations on both sides of the compartments are the same. |
|
| C. |
When particles in solution can diffuse across the membrane along with water. |
|
| D. |
When the solutes concentration on both sides of the compartments are the same. |

4. The only thing that changes in Dullsville is the price of a stay at the Dullsville Inn. You've collected the following data on the rates charged (for a suite with 2 queen-sized beds and 'free' continental breakfast) and the number of rooms occupied. The Inn has 100 suites, and at no time were potential visitors turned away due to no vacancy. Use this data to estimate a 'constant elasticity' demand function. Estimate the price elasticity of demand.

What is the effect of the following changes on the volume of 1 mol of an ideal gas? (Note: You should NOT need to do any explicit numerical calculations. Use your qualitative understanding of how volume depends on different experimental variables.)
1. The pressure is changed from 0.5 atm to 760 mm Hg (at constant temperature).
2. Another 3 mol of gas (to the existing one mol) is introduced through a stopcock (at constant temperature and pressure).
3. The pressure is halved and the temperature is changed from 0 °C to 546 K.
4. Another 1 mol of gas is introduced and the pressure is changed from 380 torr to 1 atm (at constant temperature).
5. The temperature is changed from -173 °C to 200 K (at constant pressure).
The answers are: the volumn quadrupled/doubled/halved/stays the same

What is the effect of the following changes in the O2 affinity of hemoglobin? (a) A drop in the pH of blood plasma from 7.4 to 7.2. (b) A decrease in the partial pressure of CO2 in the lungs from 6 kPa (holding one’s breath) to 2 kPa (normal). (c) An increase in the BPG level from 5 mM (normal altitudes) to 8 mM (high altitudes). (d) An increase in CO from 1.0 part per million (ppm) in a normal indoor atmosphere to 30 ppm in a home that has a malfunctioning or leaking furnace.
