Hi, the statement 2 is true but just tells about the type type combustion to which the reaction given in statement belong. it does not tell about actual cause of burning of phosphorus in air at room temperature. the reason for statement 1 is that phosphorus is a highly reactive element that's why burns in air at room temperature.

Ans 5:

Class : Class 8
the soultion is wrong beacuse the literal defination of spontaneous combustion tells us that it happens at room temprature without application of heat by external source

Why so? In both the cases soybean is present.

Ans 5:

Class : Class 8
Think in the way of leguminous crops

Ans 6:

Class : Class 6
yeah right Triguna!!! in both cases soybean is present? why so?

Ans 7:

Class : Class 9
Both Wheat and Maize require rotation of crops.

Ans 8:

Class : Class 9
Supposed to be only ABecause mustard is a non leguminous plantEven it can be rotated with soyabean

Ans 9:

Class : Class 8
The protein requirement of mustard is fulfilled by the ribozome present in root nodules of soyabean?

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......................................................................

Ans 2:

Class : Class 4

Ans 3:

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

Ans 4:

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

Ans 5:

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

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 8
the answer should "a" as acclimatisation not adaptation

Ans 9:

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 10:

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

Ans 11:

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