Final answer:
Julia should draw a diagram of compact bone tissue consisting of cylindrical osteons aligned parallel to the long axis of the bone.
Step-by-step explanation:
Julia should draw a diagram of compact bone tissue that consists of cylindrical osteons aligned parallel to the long axis of the bone. Compact bone is the dense outer layer of bones and provides support and protection. The diagram should show osteons composed of layers of compact matrix surrounding a central Haversian canal, which contains blood vessels and nerve fibers.
