Answer:
Step-by-step explanation:
After a marathon, it would be logical to predict that proteinuria would occur (protein in the urine). In addition, it would not be surprising for the runner to be dehydrated, and the amount of urine produced was less than normal.
In the person that ate salty popcorn, with greatly increases salt intake, the person would have decreased salt reabsorption, and therefore a larger amount of salt excreted in the urine. Their urine would be saltier than normal.
