Transcript text: QUESTION 10
Humans have the most urgent need for a continuous supply of $\qquad$
food
nitrogen
oxygen
water
Solution
The answer is: oxygen
Explanation for each option:
Food: While food is essential for survival, humans can survive for several weeks without it.
Nitrogen: Although nitrogen is a major component of the air we breathe, it is not directly used by the body in its gaseous form. Humans do not have an urgent need for a continuous supply of nitrogen.
Oxygen: Humans require a continuous supply of oxygen to survive. Without oxygen, brain damage can occur within minutes, and death can follow shortly after.
Water: Water is also crucial for survival, but humans can survive for a few days without it.
Summary:
Humans have the most urgent need for a continuous supply of oxygen.
