Explanation:
When there are low oxygen levels in blood, the blood pH tends to lower. This is because there is an increased level of carbon dioxide in the blood that is converted to carbonic acid by carbonic anhydrase. When carbon acid dissociates, into H⁺ and HCO₃⁻ . The H⁺ influences the increase in acidity of the blood. The kidneys will excrete most of the H⁺ and retain most of the HCO₃⁻ to help maintain the right blood pH. However, most of blood pH homeostasis is maintained largely by the lungs.

The answer to this question would be: False
The rate of diffusion should not be influenced by molecular weight. Big molecule might not be able to pass the membrane though.
Diffusion happens when there is a difference/gradient in the concentration of the molecules. If the difference is higher, then the diffusion rate will be increased.
