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.  

i'm gonna put a couple so you can chose from

explanation:

if you know the fur color of the offspring mice, you can use the ratios to identify the genotypes of the parents.

if either parent mouse passes a dominant allele, the offspring will have black fur.

if the parental mice has two different fur color (i.e white and black) , the color of the offspring's fur would be either black, white, or the combination of both (grey)

hope this : )
