Consider the following situation. During endochondral bone formation, the secondary ossification center never begins to form. What will the developing bone look like?Multiple ChoiceThe ends (epiphyses) of the bone will remain cartilaginous during development until adulthood, when the cartilage will ossify.The bone will remain in its cartilaginous model form.No epiphyseal plate will exist between the two formed ossification centers.The bone will remain cartilaginous in the middle (the diaphysis) until adulthood, when the cartilage will ossify.
