Question

question 9
which of the following is true of sweat?
○ sweat is all electrolytes.
○ sweat is mostly electrolytes, but it does have some water.
○ sweat is mostly water, but it also has some electrolytes.
○ sweat is all water.

Explanation:

Sweat's main component is water (around 99%), with the remaining ~1% being electrolytes (like sodium, chloride, potassium) and other substances. So it is mostly water with some electrolytes, eliminating the other options (sweat isn't all electrolytes, mostly electrolytes, or all water).

Answer:

C. Sweat is mostly water, but it also has some electrolytes.
