Which description includes all three principal mechanical functions of the skeleton?
Supporting the body, protecting organs, and providing a movement framework✓Правильный ответ
Protecting only the brain and performing no other mechanical role
Pushing the limbs directly without help from muscles

Объяснение
The skeleton supports body form, shields vulnerable organs, and supplies a framework that muscles pull on to create movement. Bones do not actively push limbs by themselves, because the force comes from muscle contraction.
