What is the rate of diffusion in the gas- exchange organ of an air- breathing animal where the area for gas exchange in the lung is 200 mm², the diffusion constant is 0.08, the PO₂partial pressure of oxygen) of the air in the lung is 140 mm Hg, the PO₂in blood flowing into the lung is 90 mmHg, and the thickness of the gas exchange membrane is 0.001 mm? A) 00032 B) 800,000 C) 125 D) 10,000,000

The rate of diffusion can be calculated using Fick's law of diffusion: Rate = (Area * Diffusion Constant * (P1 - P2)) / Thickness. Plugging in the given values: Rate = (200 * 0.08 * (140 - 90)) / 0.001 = 800,000.
