Answer

B Explanation 1. Identify correct physiological principle According to Fick's law of diffusion, diffusion rate is proportional to gas solubility; higher solubility increases diffusion rate across membranes. 2. Eliminate incorrect options A is incorrect — ventilation rate is determined mainly by CO₂ and pH, not solubility. C is false — solubility is indeed a factor in gas exchange. D is wrong — solubility doesn’t affect membrane thickness. E is false — gases (e.g., CO₂, O₂, N₂) have different solubilities. 3. Select correct option B correctly states that gases with higher solubility diffuse more rapidly.
