It should be mentioned NEW MOON AND FULL MOON or either Waning or waxing

Ans 2:

Class : Class 6
It should be written as New moon and Full moon as anyone could be confused that the dark side is the moon. I also put gibbous with the same thought. If it would have been marked then it would have been easier to say that the answer is the crescent moon.

Ans 3:

Class : Class 10
You should name the full moon and the new moon...

Class : Class 5

Ans 5:

Class : Class 6
I got confused and wrote gibbous thinking that the dark side of the moon is visible. You should name the other moon phases with waning and waxing or name the full moon or the new moon

C

Ans 3:

Class : Class 8
Option 'C': To store water is correct answer because a camel lives in a hot desert with scarcity of water.

Ans 4:

Class : Class 9
Camels do not store water in their humps, as it is commonly believed. The humps are actually reservoirs of fatty tissue. Concentrating body fat in their humps minimizes heat-trapping insulation throughout the rest of their body, which may be an adaptation to living in hot climates
