Neco Model Questions Vol1 2019 Biology Question 36
Practice objective / multiple choice question 36 from the 2019 Neco Model Questions Vol1 Biology examination.
In the lungs, the rate of oxygen diffusion ( \( \dot{V} \) ) is directly proportional to the alveolar-capillary surface area ( \( A \) ) and the difference in partial pressure of oxygen ( \( \Delta P \) ), and inversely proportional to the diffusion distance ( \( T \) ). At sea level the surface area is \( A \) and the diffusion distance is \( T \). If the surface area is increased by 20 % and the diffusion distance is reduced by 10 % while the partial‑pressure difference remains unchanged, by what factor does the diffusion rate change compared with the original rate?
