2..
....... cylinders are carried by
mountaineers at higher altitude.​

Answer 1

Answer:

Mountaineers carry an oxygen cylinder along with them. It is because when they climb mountains, as altitude increases, the amount of oxygen level in the atmospheric air decreases as trees are not found at higher altitudes. As a result, mountaineers suffer from dizziness. It can also lead to hypoxia.
