Answer #1

We need to first calculate the osmolarity of each compartment. Then we need to compare to corresponding osmolarities to find the relationship between the cell and its surrounding.

The calculations are as below:

Hope this helps. Please let me know if you have any query.

Best wishes!!

Cholera and other diarrheal diseases cause nearly 2 billion cases of diarrhea annually. Cholera toxin and other bacterial toxins cause the intestine to secrete fluid into the lumen of the gut, depleting the extracellular fluid (ECF) volume. If fluid loss is not matched with fluid intake (law of mass balance), the result is severe dehydration, circulatory collapse, and even death. Drinking a rehydration solution is the most rapid and effective way to replace the large volumes of water lost by...
