Mangrove plants live in areas regularly flooded with salt water. Which of these is not a possible mechanism for controlling their salt balance?  

A.  The roots block salt uptake.
B.  The succulent leaves contain large quantities of water that dilute salt that is absorbed.
C.  Absorbed salt is secreted from special salt glands.
D.  Modified roots emerge above the water level and help oxygen diffuse into the roots.
E.  Excess salt is stored in special tissues.


D.  Modified roots emerge above the water level and help oxygen diffuse into the roots.
Many plant adaptations have evolved for dealing with salt in the environment.

How do most motor proteins ensure their movements are unidirectional?

A.) they couple a conformational change to a thermodynamically unfavorable reaction B.) they couple a conformational change to the hydrolysis of an ATP molecule C.) they couple a conformational change to the formation of an ATP molecule from ADP and Pi D.) they hydrolyze their bound GTP, effectively preventing movement in the reverse directoin E.) their asymmetrical structures support movement in only one direction
