Explanation:

For Question 19, the Body - Mass Index (BMI) is calculated using a person's weight and height. The formula is $BMI=\frac{weight(kg)}{height(m)^2}$. For Question 20, during light - intensity activities like a short walk, the body primarily uses glycogen as an energy source. Glycogen is stored in the liver and muscles and can be quickly broken down into glucose for energy.

Answer:

Question 19: C. height and weight
Question 20: B. glycogen
