Low concentration of oxygen in the blood and tissues of people living at high altitude is due to:
1 Low temperature
2 Low atmospheric pressure
3 High atmospheric pressure
4 Both low temperature and high atmospheric pressure
Explanation:
Low concentration of oxygen in the blood and tissues of people living at high altitude is due to low atmospheric pressure. Because at high altitude, the partial pressure of oxygen is less than at the ground level.

Assertion : On opening a sealed soda bottle, dissolved carbon dioxide gas escapes. Reason : Gas escapes to reach the new equilibrium condition of lower pressure.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Carbon dioxide is sealed in soda bottle under high pressure. When the bottle is opened, the gas escapes from inside high pressure to outside low pressure. So option (1) is correct.

Four gases like \({{\rm{H}}_{\rm{2}}}{\rm{,He,C}}{{\rm{H}}_{\rm{4}}}\,\,{\rm{and}}\,\,{\rm{C}}{{\rm{O}}_{\rm{2}}}\) have Henry’s constant values \(\left( {{{\rm{K}}_{\rm{H}}}} \right)\) are 69.16, 144.97, 0.413 and 1.67. The gas which is more soluble in liquid is
1 \({\rm{He}}\)
2 \({\rm{C}}{{\rm{H}}_{\rm{4}}}\)
3 \({{\rm{H}}_{\rm{2}}}\)
4 \({\rm{C}}{{\rm{O}}_{\rm{2}}}\)
