Question

select the correct answer.
kima is an athlete and weighs more than her sister, who is of the same height. what could be the reason?

a. kima has more muscle mass than her sister because she is more athletic.

b. as part of her athletic regimen, kima takes several supplements that add to her weight.

c. to fuel her high level of activity, kima consumes extra calories and carbohydrates.

Explanation:

Muscle is denser than fat, so an athlete (Kima) with more muscle mass (due to being athletic) can weigh more than her non - athletic sister of the same height. Option B about supplements adding weight is less likely as supplements are not a typical main reason for weight difference between siblings of same height. Option C about extra calorie intake for activity doesn't necessarily mean she'll weigh more as the calories could be used for energy and muscle building, but the key reason for weight difference in same - height individuals is muscle mass.

Answer:

A. Kima has more muscle mass than her sister because she is more athletic.
