Final answer:
Bone responds to stress by undergoing bone remodeling, with increased osteoblast and osteoclast activity. Trabeculae may also be formed to increase bone strength.
Step-by-step explanation:
Bone responds to stress by undergoing bone remodeling, which involves a balance between osteoblast activity and osteoclast activity. When stress is applied, osteoblast activity increases to build new bone tissue, while osteoclast activity increases to break down old bone tissue. This allows bones to become thicker and stronger in response to stress.
Additionally, bones may also respond to stress by forming trabeculae, which are small bony projections. Trabeculae can be formed perpendicular to the zone of stress to increase the strength of the bone.
