How would water and oxygen through the alveoli cell membrane differ?

The alveoli is the functional unit of the lungs responsible for gas exchange. Water is not exchanged in the lungs therefore water pressure difference are not significant in this case. Oxygen on the other hand, there will be a significant difference from the partial pressure of oxygen in the environment compared to the partial pressure of oxygen in the alveoli cells and the lung capillaries. The partial pressure of oxygen in the alveoli cells and the lung capillaries are lower than the partial pressure of oxygen in the environment. This pressure gradient predicts the direction of diffusion from environmental oxygen to the alveoli then to the lung capillaries, and this process is called oxygenation. 

Swating at a bee and it stings

if, i suppose that a bee stings me swinging my hand away from a bee. then that if, i persist patient when a bee or wasp areas on your surface to investigate a scent or to take h2o and i secreting heavily, the bug ultimately will move of its personal agreement. if i don't need to set for it to disappear, lightly and gently wipe it off with a part of the paper.

It depends on the surface of the levels. the rougher the surface, the greater is the frictional force. for rougher surfaces, you would need to exert greater force to move the object. the concept is that, you must overcome the frictional force in order to bring the object into motion. this is the reason why we add lubricants to the joints so they could easily move. this answer was on
