Answer:
the alveoli are made of thin squamous (type I) alveolar cells which allows for the quick diffusion carbon dioxide and oxygen.
Explanation:
Diffusion of gases takes place between the alveolar cavity and the blood in the capillaries. Oxygen being more concentrated in the alveoli diffuses across the epithelium of the alveoli and the endothelium of the capillaries into the blood. The epithelial walls of the alveoli are moist and thin thus enhancing the diffusion.
The element carbon makes long chains forming, single, double or triple bonds with itself.
Explanation:
if a trait A exists in 10% of a population of an asexually reproducing species and a trait B exists in 60% of the same population, trait B is likely to have arisen earlier because this trait has been replicating and existing in a higher percentage of the population as compared to trait A.
