Compare the atp available to cells when oxygen is present versus when it is absent. how might this explain why brain and heart functions are so quickly affected when a person cannot breathe?

As brain and heart are vital organ they affected negatively when oxygen is lower as they generally require a lot of energy by oxidizing the glucose available so if oxygen is lower glucose available can't be well utilized thus lower energy and poor performance

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.
