Which option correctly separates gases related to protection of life and a life process?
Answer and explanation
Correct answer: Ozone protects against ultraviolet radiation and oxygen supports respiration
Stratospheric ozone absorbs much of the Sun’s harmful ultraviolet radiation, thereby protecting living organisms. Oxygen is used in aerobic respiration, allowing cells to release energy from food. The two gases therefore have different but important roles stated in option A. Nitrogen and argon do not perform the roles described in option B, carbon dioxide is mainly a photosynthesis raw material, and the claims about argon and nitrogen in option D are incorrect.
