A pressurized airplane cabin and an oxygen tent over a patient in a hospital both address the need of a person for oxygen. How do these compare?
Select one:
a. The oxygen tent increases the air pressure to increase the PO2.
b. Airplane cabin pressure lowers the partial pressures for normal breathing.
c. Both use the same mechanism to force hemoglobin to increase affinity for oxygen.
d. The oxygen tent increases concentration of O2 while the airplane maintains total air pressure without changing concentrations.
e. Both increase the PO2 in order to force the exchange of oxygen for carbon dioxide.
d. The oxygen tent increases concentration of O2 while the airplane maintains total air pressure without changing concentrations.

A newborn chick can accurately peck at food without other chicks around to serve as models. Newborn geese considered Konrad Lorenz to be their mother because he was the first creature they saw and heard after they hatched. Are these the same "type" of inherited behavior? Compare and contrast these two behaviors.
