Question

true or false 10 points
as humans age, there is a natural increase in fat mass coupled with a gradual decline in lean mass, specifically in bone and muscle mass.
true
false

Explanation:

As humans age, physiological changes occur. Fat mass tends to increase due to factors like hormonal changes (e.g., reduced growth hormone and testosterone levels in men, estrogen changes in women) and decreased physical activity. Lean mass (including bone and muscle) declines. Bone density decreases (osteoporosis risk increases) as bone remodeling (resorption outpaces formation over time). Muscle mass reduces (sarcopenia) due to motor neuron loss, reduced protein synthesis, and less physical stress on muscles. These are natural age - related processes (though lifestyle factors like exercise and diet can modify their extent).

Answer:

True
