People do not only breathe in oxygen.

In fact, when breathing in normal air, you only take in about 21% oxygen, the rest of the gasses being mainly nitrogen (about 79%). As for breathing out, it is mainly carbon dioxide, but there are a couple more gasses in there.

What lead many citizens of eastern europe nations to rebel against their communist governments
Dafna11 [192]
There are multiple answers to that question... Since it seems they expect you to list common factors for the Eastern European dissatisfaction with their communist governments rather than choosing one from a multiple choice list, here are some possible answers:
- Most communist regimes were comprised (and dominated) by small groups of individuals who refused many communist beliefs.
- The economic situation of Eastern European communist countries was really deplorable, and their citizens realized this through the media (TV, newspapers, etc..)
- Certain ideological, religious groups (such as the Polish Catholic Church) provided some leadership to the opposition.
- These countries could not compete with capitalist Western countries in terms of economy and medicine.
- Americans made promises to the new countries after they got rid of communism; letting multi-nationalism take over.

How many years did it take the paleo Indians to travel to Alaska?
Stolb23 [73]

Answer:

Evidence of the latter would since have been covered by a sea-level rise of more than a hundred meters following the end of the last glacial period. Archaeologists contend that Paleo-Indians migrated out of Beringia ( western Alaska ), between c. 40,000 and c. 16,500 years ago. This time range remains a source of substantial debate.
