Explanation:

Question 40

To determine the most abundant protein in the body, we recall biological knowledge: Collagen is the most abundant protein, providing structural support. Elastin is for elasticity, reticular is a type of fiber, and adipose is fat (not a protein in the same structural sense).

In human anatomy, the subpubic angle differs by sex. Females have a wider subpubic angle (often >90°) for childbirth, while males have a narrower angle. A 110° angle is wide, indicating a female pelvis.

For long bones, the diaphysis is the main shaft - like portion. Epiphysis is the end, articular cartilage covers joints, and periosteum is the outer membrane. So the shaft - like part is diaphysis.

Answer:

B. collagen
