While traveling through the rain forest of peru, you are introduced to a rare and exotic plant. you discover that it contains a toxin that blocks the reabsorption of sodium ions from the proximal tubule. if administered, what affect would this toxin have on the reabsorption of glucose? while traveling through the rain forest of peru, you are introduced to a rare and exotic plant. you discover that it contains a toxin that blocks the reabsorption of sodium ions from the proximal tubule. if administered, what affect would this toxin have on the reabsorption of glucose?

a. the toxin would significantly decrease the amount of glucose reabsorbed.
b. the toxin would significantly decrease the amount of glucose in the filtrate.
c. the toxin will have no effect on the reabsorption of glucose.
d. the toxin would significantly increase the amount of glucose reabsorbed.

The correct answer is statement A.

Explanation:

Glucose, NaCl, NaHCO3, amino acids, and other organic molecules are reabsorbed through a particular transport system in the early proximal tubule known as a proximal convoluted tubule. The prime function of the proximal convoluted tubule is to perform selective reabsorption of water, glucose, peptides, and other nutrients from the tubule back into the blood.  

Thus, if the toxic possesses the tendency to prevent the reabsorption of sodium ions then it will also possess the tendency to prevent the reabsorption of glucose by the proximal convoluted tubule.  

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
