Class : Class 2

Ans 5:

Class : Class 7
I also agree with all of you . That's just impossible, I guess.

Ans 6:

Class : Class 6
We can express process v as deposition and how did condensation and freezing get involved

Ans 7:

Class : Class 6
I do agree with Bhabani prasad

Ans 8:

Class : Class 6
gas to solid is deposition and opposite is sublimation ans wrong

Ans 9:

Class : Class 7
The answer can be B and D both.

Ans 10:

Class : Class 8
I ALSO AGREE WITH YOU ALL

Ans 11:

Class : Class 7
it is a direct change, so it does have to turn into liquid state

Ans 12:

Class : Class 6
How in processes v condensation came?

Ans 13:

Class : Class 9
Answer is B because to turn Water vapour into ice you need Deposition but water vapour cannot be deposited that is why you first need to turn the water vapour to water by condensation and then to convert water to ice you need freezing . Hence answer B is correct

I prefer option C

Ans 7:

Class : Class 5
C

Ans 8:

Class : Class 8
The correct ans is option C because electrostatic force is a non contact force which is similar to magnetic force and the comb is like a magnet and tin pieces of paper are like the metal here (So the comb will attract the tiny pieces of paper).

Ans 9:

Class : Class 5
The answer is C

Ans 3:

Class : Class 4

Ans 4:

Class : Class 7
IDIOTS just listen to them or maybe they are wrong

Ans 5:

Class : Class 7

Class : Class 6
mammals do not have 6 legs and has more han 1 eye!

Ans 7:

Class : Class 5
ans is DBECAUSE IT IS A IMAGINARY ANIMAL

Ans 8:

Class : Class 5
Firstly , mammals do not have three eyes, secondly which mammal has six legs ???????????

Ans 9:

Class : Class 8
Mammals do not have 3 eyes

Ans 10:

Class : Class 7
This is impossible because a cow has four legs not 6 legs and also it has two eyes not one eye and those two eyes are not on the forehead

Ans 11:

Class : Class 9
The answer is D. Hair on skin and breast feeding the young ones are characteristic of mammals such as cow. So, if really existed, this animal would have been placed with cow.

Ans 12:

Class : Class 8
Is cow have 6 legs and 1 eye on its forehead

Ans 13:

Class : Class 5
Yes but in the question it said that the animal was imanginative can't believe what type of an animal it was.

Ans 14:

Class : Class 5
forehead? hahahahahahahahah

Ans 15:

Class : Class 8
this question makes no sense . 6 legs-can be an insect , eye on his forehead???

Ans 16:

Class : Class 5

Ans 17:

Class : Class 4

Ans 18:

Ans 20:

Class : Class 7
Idiots, the monster fed milk to its young, a feature seen only in Mammals

Ans 21:

Class : Class 5
I thought this could be an insect as it HAS SIX LEGS. And some spiders( I know they are not insects ) have more than two eyes so it could be possible that the correct answer is b. But it has fur and is feeding its young one milk so the answer should be d

Ans 22:

Class : Class 7
As this question is already wrong a mammal can not have 6 legs.

Ans 23:

Class : Class 4

Ans 24:

Class : Class 4
If this animal really existed it would have to be a monster that would eat us

Ans 25:

Class : Class 8
If the animal really existed it would have belonged to the same group as cow.
