Question

Which student produced urine with the lowest concentration of sodium chloride at the 40 minute mark?

A. The student who drank tomato juice, which had the same sodium concentration as blood plasma.
B. The student who drank soda, which had no sodium.
C. The student who drank nothing.

Answer 1

The student who drank soda likely produced urine with the lowest concentration of sodium chloride at the 40 minute mark.

Step-by-step explanation:

In order to determine which student produced urine with the lowest concentration of sodium chloride at the 40 minute mark, we need to consider the options given.

Option A states that the student who drank tomato juice had the same sodium concentration as blood plasma. Since blood plasma has a lower sodium concentration compared to urine, this student's urine would not have the lowest concentration of sodium chloride.

Option B states that the student who drank soda had no sodium. Since sodium chloride is composed of sodium and chloride, consuming soda would result in urine with a low concentration of sodium chloride. Therefore, the student who drank soda likely produced urine with the lowest concentration of sodium chloride at the 40 minute mark.

Option C states that the student who drank nothing would not introduce any sodium chloride into their system, resulting in urine with low or no concentration of sodium chloride.

Based on this information, the correct answer would be Option B: The student who drank soda, which had no sodium.
