Question

question 1
spongy bone tissue:
a is very dense
b contains interconnecting plates called trabeculae
c contains concentric lamellae
d is the primary component of compact bone
e has many spaces and lacks osteocytes

Explanation:

Spongy bone tissue, also known as cancellous bone, has a porous structure. It contains interconnecting plates called trabeculae. Dense bone is compact bone (so A is wrong). Concentric lamellae are in osteons of compact bone (so C is wrong). Spongy bone is not the primary component of compact bone (so D is wrong). Spongy bone has osteocytes within lacunae (so E is wrong).

Answer:

B. contains interconnecting plates called trabeculae
