Answer 1

If a drug that blocked the reabsorption of sodium were taken, what would happen to the reabsorption of glucose?

B. Decrease

If a drug that blocked the reabsorption of sodium were taken, what would happen to the reabsorption of water?

B Decrease.

(Explanation: if the reabsorption of sodium is blocked, both the reabsorption of glucose and water will be decrease as both need sodium ions. Their transport in one or the other way is coupled to that of sodium. The transport of glucose is dependent on the energy stored in the sodium gradient, it needs to be co-transported with the sodium. similarly the movement of water molecules follows the movement of sodium ions. Thus reabsorption of both glucose and water decreases).
