Answer:
The actual answer to the question: Factors that determine how much water intake is needed on a daily basis include all of the following except:______, would be, B: Body composition.
Step-by-step explanation:
Human males and females have a pre-set level of water mass, in relation with their muscle and fat composition, that does not change throughout time, regardless of how much water is consumed in a given day. This body composition will not, either, affect the percentage of daily water needed, as it is maintained stable by different mechanisms of response in the body, like sweating and urination. However, exercise, gender and age will affect the daily percentage as they are factors that determine how much water is needed for each of the two sexes, and how much water is lost, depending on muscle and fat mass, and definitely exercise levels.
