Q: Answer the following question given this paragraph: Connective tissue Bone remodeling and repair: bone has mineral structure, and develops tiny fractures, which, under stress, can lead to larger fractures. To combat this, bone is constantly replaced. Osteoclasts channel through existing bone, tear down and leave behind osteoblasts and lacuna, leaving osteocytes. Continually resets mineral structure of bone, and is preventative maintenance. When bone broken, callus forms in open ends, periosteum gives rise to new bone with calcium and new bone matrix, leaves irregular mend. Later, osteoblasts continue fixing over time and slowly removing imperfection. Q: Osteoclasts and osteoblasts play key roles in repair of what? A:

OPTIONS:
- heart
- liver
- brain
- bone

A:
bone
