Question

unlike cartilage, bone has cells within lacunae. has an outer covering. undergoes remodeling throughout life. has a matrix that contains collagen. is a connective tissue.

Explanation:

1. Analyze option "has cells within lacunae": Both cartilage and bone have cells (chondrocytes in cartilage, osteocytes in bone) within lacunae, so this is not a difference.
2. Analyze option "has an outer covering": Both cartilage (perichondrium) and bone (periosteum) have outer coverings, so this is not a difference.
3. Analyze option "undergoes remodeling throughout life": Bone undergoes remodeling (breakdown and formation) throughout life, while cartilage has limited repair/remodeling capacity. This is a key difference.
4. Analyze option "has a matrix that contains collagen": Both cartilage and bone matrices contain collagen, so this is not a difference.
5. Analyze option "is a connective tissue": Both cartilage and bone are connective tissues, so this is not a difference.

Answer:

C. undergoes remodeling throughout life.
