question 7 (3 points)
kim is an athlete and weighs more than her sister, who is of the same height. what could be the reason?
as part of her athletic regimen, kim regularly cuts her caloric intake to reduce her weight.
to fuel her high level of activity, kim consumes extra calories and carbohydrates.
kim has more muscle mass than her sister because she spends more time being physically active and building muscle.

Explanation:

Muscle is denser than fat. Athletes like Kim, who are physically active and build muscle, have more muscle mass. Even at the same height, more muscle mass can lead to a higher weight compared to someone with less muscle (like her sister). Cutting caloric intake (first option) would likely reduce weight, not increase it. Consuming extra calories and carbohydrates (second option) doesn't directly explain higher weight in terms of body composition (muscle vs fat) as effectively as the muscle - mass explanation.

Answer:

Kim has more muscle mass than her sister because she spends more time being physically active and building muscle.
