question 14

the hormone that increases cell division in growing bones is:

growth hormone

Explanation:

The sternum (breastbone) is a long, flat bone in the center of the chest. In the diagram of the thoracic cage, the sternum is typically represented by the central vertical bone. Looking at the labels, the sternum is identified by the combination of the manubrium (E), body (F), and xiphoid process (G), but the overall sternum structure is marked by the central vertical bone, which in the diagram corresponds to the region covered by E, F, G. However, if we consider the main label for the sternum as a whole, the arrow that points to the sternum (combining its parts) is associated with the central vertical structure. From the labels, the sternum's body is often the middle part, but the sternum as a whole is the central bone. In the diagram, the sternum is represented by the structure that E, F, G are pointing to. But if we have to pick the label for the sternum (as a whole, or its main part), the sternum's body is F, but the sternum includes manubrium (E), body (F), xiphoid (G). However, in typical diagrams, the sternum is labeled with the central vertical bone, so the answer is the label that points to the sternum, which is the combination, but if we look at the labels, the sternum is the central bone, so the correct label for the sternum (the bone) is the one pointing to the central vertical bone, which is F (or the combination of E, F, G, but in the diagram, the sternum is the central bone, so the label for sternum is F (body of sternum) or the overall sternum. But in the diagram, the sternum is the central bone, so the answer is the label that points to the sternum, which is F (or E - G, but likely F as the body, or the central part). Wait, the question is to identify the sternum. The sternum has three parts: manubrium (top, E), body (middle, F), xiphoid process (bottom, G). So the sternum is the entire central bone, so the label for the sternum (the bone) is the one that includes E, F, G, but in the diagram, the arrows E, F, G are pointing to the sternum's parts. But the question is to identify the sternum (the bone), so the correct label is the one that points to the sternum, which is the central vertical bone. So looking at the labels, E is manubrium, F is body, G is xiphoid. So the sternum is the bone with E, F, G. But the question is to identify the sternum, so the answer is the label that points to the sternum, which is F (body) or the combination. But in the diagram, the sternum is the central bone, so the correct label is F (or E - G, but likely F as the main part). Wait, maybe the answer is F? Or E? No, the manubrium is E, body F, xiphoid G. The sternum is the entire bone, so the label for the sternum (the bone) is the one that points to the sternum, which is the central vertical bone, so F (body) is part of it, but the sternum is the whole thing. But in the diagram, the arrow F is pointing to the body of the sternum, which is the main part. So the answer is F? Or maybe E, F, G together. But the question is to identify the sternum, so the correct label is the one that points to the sternum, which is F (body) or the central bone. So the answer is F (or the label for the sternum is F, as the body of the sternum is the main part).

Answer:

F (the label pointing to the body of the sternum, which is part of the sternum bone)
