3.
In an experiment, the efficiency of oxygen exchange across the plasma membrane is being assessed in four
artificial red blood cells. The table above lists some properties of those artificial cells. Other conditions
being equal, which artificial cell is predicted to be the most efficient in exchanging oxygen with the
environment by diffusion?
A The cuboidal cell
B The tetrahedral cell
C The cylindrical cell
D The spherical cell
The following questions refer to the following diagram. For each phrase or sentence, select the labeled part to
which it is most closely related. Each option may be used once, more than once, or not at all for each group.
