  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

  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'

  2. Hydra

  3. Earthworm

  4. Blue jay

  5. Frog

Show answer
Correct Option: D
Explanation:

The organisms that use external heat to maintain their body temperature are termed as ectotherms while those maintaining their body temperature using the metabolic heat are termed as endotherms (mammals and aves). Among the given options, Blue jay (aves) is endotherms. 

Therefore, the correct answer is option D.

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

  1. True

  2. False

Show answer
Correct Option: A
Explanation:

At the molecular level even living things are fundamentally made up of all the elements that make non-living matter. There have been attempts to make these molecules and their integration to create life by scientists but none of them has been successful yet. Hence, it is often believed that there is a vital force that can not be created by us that gives organisms characteristics of life. 

So, the correct option is 'True'.

Two opposite forces operate in growth and development of every population. One of them has ability to reproduce at a given rate.
