Question

1. an adult with a bmi of 27 would be classified as a. underweight b. healthy weight c. overweight d. obese 4. which method is commonly used to estimate body fat using electrical signals? a. dxa scan b. underwater weighing c. air displacement d. bioelectrical impedance

Explanation:

Question 3

BMI (Body Mass Index) categories: Underweight is BMI < 18.5, Healthy weight is 18.5 - 24.9, Overweight is 25 - 29.9, Obese is ≥ 30. A BMI of 27 falls in the 25 - 29.9 range, so it's Overweight.

Bioelectrical impedance uses electrical signals to estimate body fat by measuring how the body resists the current (different tissues have different resistances). DXA scan uses X - rays, underwater weighing and air displacement are based on density principles, not electrical signals.

Answer:

C. Overweight
