Final answer:
Five percent of an adult's skeletal mass is broken down and rebuilt each year, which is essential for maintaining bone health and repairing damage.
Step-by-step explanation:
The question regarding the amount of an adult's skeletal mass that is broken down and rebuilt each year relates to the process of bone remodeling. The correct answer to this question is B, which states that 5 percent of an adult's skeletal mass is broken down and rebuilt annually. This continuous process of bone remodeling is essential for bone health, allowing the skeleton to adapt to stress and repair damage. It involves the activities of cells called osteoclasts that break down old bone and osteoblasts that form new bone. Understanding this process is important for fields such as medicine and physiology.

Diet plays a crucial role in the health and growth of domestic swine. It is recommended to feed domestic swine no more than 2% of their body weight to maintain their ideal body condition.
Excess feeding can lead to obesity and related health issues, while underfeeding can result in malnourishment and stunted growth. By feeding swine an appropriate percentage of their body weight, their nutritional needs are met without compromising their overall health and well-being.
