Explanation:

For Question 15:

• Bone repair starts with hematoma (blood clot) formation at the fracture site.
• Then, a fibrocartilaginous callus (soft callus) forms to stabilize the area.
• Next, a bony callus (hard callus) replaces the fibrocartilaginous callus.
• Finally, bone remodeling occurs to reshape the bone.

For Question 16:

• The sternum is a flat bone. Flat bones are thin, flattened, and often curved. They provide protection (e.g., for the heart and lungs by the sternum and ribs) and serve as attachment sites for muscles.

Answer:

Question 15: hematoma forms, fibrocartilaginous callus forms, bony callus forms, bone remodeling occurs (the second option).
Question 16: flat bone (the third option).
