What is the partial pressure elevation of O2 at the top of mt. Everest (elevation 29,029) in mmHg if atmospheric pressure is 250 mm Hg? Assume that the air is still 20.9% O2. Explanation plz... I don’t understand this. Thank you :)

i think its through the fallopian tube

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.

the answer is c. it will give up it's valence electron to the other atom.
