Ans 5:

Class : Class 4
Acclimatization and adaptation mean two totally different things. Adaptation means permanent adjustment to our habitat whereas acclimatization means temporary adjustment to a place where we temporarily stay for some time and get used to. In my opinion, option A is the right answer.

Ans 6:

Class : Class 8
the answer should "a" as acclimatisation not adaptation

Ans 7:

Class : Class 8
the answer should "a" as acclimatisation not adaptation

Ans 8:

Class : Class 6
The answer is A. You should Read the book twice again. But even then also you think that the answer is B than the book is a spam. Adaptation is the permanent feature of an organism which helps it to survive in its habitat, while acclimatisation is a temprory feature or change in feature of an organism which helps it to survive in any other place rather than its habitat......................................................................
