Which of the following play(s) a role in determining a persons weight? a) heredity b) activity level c) bmi d) body composition (:

D- body composition plays a role in determining a persons weight. Heredity doesn’t state how much someone weights. Activity level may help predict that someone’s overweight but doesn’t tell how much someone actually weights. BMI can't distinguish between fat and muscle, which tends to be heavier and can tip more toned individuals into overweight status, even if their fat levels are low.

body composition is used to describe the percentages of fat, bone, water and muscle in human bodies. Because muscular tissue takes up less space in our body than fat tissue, our body composition, as well as our weight, determines leanness.
