Answer: Read Explanation
Explanation:
The "gas filled balloon" moves up, then the "upward force is larger" than the "force of gravity". The gas filled balloon causes the weight of the balloon to be heavier and hence, the force of gravity which acts on the balloon is also more than normal weight.
But in order to cause the upward motion of the balloon the upward force must overcome that weight so as to lift, therefore will be larger than the force of gravity.
1. True
2. Warm up and cool down when exercising
3. Skeletal system
A: The pathway of air goes from the nasal cavity (or oral cavity) to the pharynx to the trachea to the primary bronchi (right and left) to the secondary bronchi to the tertiary bronchi to bronchioles to the alveoli (site of gas exchange)
B: when relaxed, the diaphragm is a dome shape. when we inhale, the diaphragm flattens down, increasing the thorax volume. this reduces the pressure in the thorax, so air moves into the lungs to equalize the pressure. when we exhale the diaphragm moves back into its relaxed dome position.
