Answer to Question 1

D
Bioavailability is the amount of a mineral that can be absorbed by the body from a food. It is generally lower than the total amount of the mineral in a food. It may be related to the ratio of free to bound mineral in a food, but that is only one of many factors affecting bioavailability. It is not related to the amount excreted by the body.

Answer to Question 2

A
Edema may be caused by inadequate intake of protein if protein levels in the body become so low that cellular fluid levels become imbalanced. Edema may be caused by high, not low, sodium levels and is not caused by low chloride or potassium levels.
