b) mixture of Ne and O2 d) mixture of He,02 and Ar​

Answer 1

Answer:

An oxygen-helium mixure is used artificial respiration in deep sea diving instead of air because nitrogen present in air dissolves in blood under high pressure when sea diver goes into deep sea.

Answer 2

Which of the following is used for the respiration of sea divers?
