Question

question 12 (1 point) ✓ saved
the increase in the number of adipocytes in the body during growth spurts is known as

mutation.
maturation.
hyperplasia.
hypertrophy.

question 13 (1 point) ✓ saved
bioelectric impedance analysis is based on the fact that:

fat weighs more than water
fat is a poor conductor of electricity
infrared light is deflected by muscle and not by fat
muscle impedes electric current flow more than fat

question 14 (1 point) ✓ saved
national programs that aim to reverse the trend of increasing body weight should focus on

smoking cessation.
maintenance of ideal body weight.
monitoring annual weight changes.
achievement of a healthier body weight.

Explanation:

• Question 12: Hyperplasia refers to an increase in the number of cells. In the context of adipocytes during growth - spurts, this is the correct term. Mutation is a change in DNA, maturation is related to development and function rather than cell - number increase, and hypertrophy is an increase in cell size, not number.
• Question 13: Bioelectric impedance analysis works because fat is a poor conductor of electricity. This property allows for the differentiation of fat mass from other body components based on how electrical current flows through the body. Fat does not weigh more than water, and muscle conducts electricity better than fat, not the other way around. Infrared light is not related to bioelectric impedance analysis in this context.
• Question 14: National programs aiming to reverse the trend of increasing body weight should focus on achieving a healthier body weight. Smoking cessation is related to smoking - related health issues, maintenance of ideal body weight is more about keeping a current healthy weight rather than reversing an upward trend, and monitoring annual weight changes is a method, not the main focus of the program.

Answer:

Question 12: hyperplasia
Question 13: Fat is a poor conductor of electricity
Question 14: achievement of a healthier body weight
