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

zoology environmental factors environmental factors and their measurements climate factors marine life

  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.

  4. Nitrogen concentration is already more in the cells so it is not at all absorbed.

Show answer
Correct Option: B
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

Show answer
Correct Option: D
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.

Biome is ____________.

zoology environmental factors environmental factors and their measurements climate factors marine life

  1. part of the planet and its atmosphere

  2. Interacting communities of organism and its environments

  3. Biotic flora of a place

  4. Biotic fauna of a place

Show answer
Correct Option: B
Explanation:

Biome is an interaction between various communities of organisms and the environment they live in. These communities of organisms dwell in similar geographical, climatic and other biotic factors.

Example-Tundra, Grasslands etc
So, the correct answer is 'Interacting communities of organism and its environments'


Species diversity generally increases as one
proceeds from


zoology environmental factors environmental factors and their measurements climate factors marine life

  1. Low altitude to high altitude, and from low latitudes to high latitudes

  2. High altitude to low altitude, and from low latitudes to high latitudes

  3. High altitude to low altitude, and from high latitudes to low latitudes

  4. Low altitude to high altitude, and from high latitudes to low latitudes

Show answer
Correct Option: C
Explanation:

The environmental conditions in these region are favourable and hence species have become diversified.

During unfavourable conditions most of the fresh water sponges and few marine sponges from gemmules, they are

zoology environmental factors environmental factors and their measurements climate factors marine life

  1. Reduction bodies

  2. External buds

  3. Internal buds

  4. Masses of interstitial cells surrounded by spicules

Show answer
Correct Option: C
Explanation:
Gemmules are internal buds containing archaeocytes, mostly found in freshwater sponges, these are concerned with asexual reproduction.
These are formed by the sponges under unfavourable conditions.
So, the correct option is 'internal buds'
