Question

question 1 of 20 which of the following does not have an impact on a persons metabolic rate? a. gender b. age c. hereditary factors such as body shape. d. ethnicity

Explanation:

To determine which factor does not impact metabolic rate, we analyze each option:

• Option A (Gender): Males generally have more muscle mass and higher metabolic rates than females, so gender impacts metabolic rate.
• Option B (Age): Metabolic rate typically decreases with age due to changes in body composition (e.g., less muscle, more fat) and reduced activity levels.
• Option C (Hereditary factors like body shape): Heredity influences body composition (e.g., muscle - fat ratio, body size), which affects metabolic rate. For example, a person with a more muscular build (influenced by heredity) will have a higher metabolic rate.
• Option D (Ethnicity): There is no consistent, direct evidence that ethnicity itself impacts metabolic rate. Metabolic rate is more closely related to factors like body composition, age, gender, and activity level, rather than ethnicity.

Answer:

D. Ethnicity
