True
The answer is true.
When you jump, your body propels itself upward by exerting force on the ground. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. So, when you push down on the ground to jump, the ground pushes back with an equal force, propelling you upward.
In reference to cells, the answer is cilia.
Yes. The spinal bones over the shoulders are such skeletal structures.
The epiglottis closes the entrance to the trachea during swallowing.
The epiglottis guards the entrance of the glottis, the opening between the vocal folds and the entrance to the lungs.=It is normally pointed upward, but during swallowing, elevation of the hyoid bone draws the larynx upward; as a result, the epiglottis folds down to a more horizontal position. In this position it prevents food from going into the trachea and instead directs it to the esophagus, which is more posterior, into the stomach.=
