When we breathe in air, nitrogen also goes inside along with oxygen. What is the fate of this nitrogen?

  1. It moves along with oxygen into the cells
  2. It comes out with the $CO _2$ during exhalation

  3. It is absorbed only by the nasal cells.

B Correct answer
Explanation

In atmosphere, the nitrogen is present in large quantity about 78%. In our body, nitrogen is about 3%. During inspiration we take $O _2$ with various gases and nitrogen is one of them. During exhalation, the nitrogen comes out with $CO _2$.

Greenhouse gases are

  1. CO$ _{2}$
  2. CH$ _{4}$

  3. CFC

  4. All of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Green house gases (e.g. CO$ _{2}$, CH$ _{2}$, CFCs etc.) are increasing in the atmosphere due to human and natural activities. These gases trap the heat(infra-red radiation) reflected by the earth. This heats up the atmosphere(leads to an increase in earth's temperature). This phenomenon is called global warming which occurs due to green house effect.
