If you have ever hiked or climbed to high altitudes in the mountains, you surely have noticed how short of breath you get. This occurs because the air is thinner, so each breath contains fewer O2 molecules than at sea level. At the top of Mt. Everest, the pressure is only 13atm. Air contains 21.0 % O2 and 78.0 % N2, and an average human breath is 0.480 L of air.

Part A) At the top of Mt. Everest, how many O2 molecules does each breath contain when the temperature is -10.0 ∘F?

Express your answer as number of molecules.

Part B) What percent is this of the number of O2 molecules you would get from a breath at sea level at -10.0 ∘F?

Express your answer as a percentage.

At high altitudes, the oxygen level in air is low. Climbers of very tall mountains risk altitude sickness, which is characterized by shortness of breath, weakness, dizziness and confusion. The early symptoms of cyanide poisoning are the same as those for altitude sickness. Cyanide binds tightly to Cytochrome c oxidase, a protein complex that is the last component of mitochondrial electron transfer chains. Cytochrome c oxidase with bound cyanide can no longer transfer electrons. Explain why cyanide poisoning starts with...

High in the Rocky Mountains, a biology research team has drained a lake to get rid of all fish. After the lake was refilled, they stocked it with an endangered species of Greenback trout. Of the 2000 Greenback trout put into the lake 900 were tagged for later study. An electroshock method is used on individual fish to get a study sample. However, this method is hard on the fish. The research team wants to know the smallest number of...
