Subject :NSO    Class : Class 4

Refer to the given conversation among three friends.

All of our teeth have same basic structure of root, neck and crown and are made of a tough material called dentine.

If small intestine is removed from the body, digestion of food will take place but absorption of water from food will not occur.

The teeth at the back of jaw are premolars and molars. They both are found in milk teeth set as well as permanent teeth set.

I agree with the solution given. Anand is right as a tooth also includes dentine as well as enamel. If it would have been,'The covering of a tooth is dentine.',it was wrong. Bhavya Jain check the solution.

Look here there is some problem. The correct answer is not there. Amrit is right. but all are not wrong. Anand and Rajesh are wrong. So, the correct answer will be E (which is not there actually. I made it myself because the correct answer was not there.) Rajesh and Anand.

Ans 24:

Class : Class 5
the correct answer is c because premolars and molars are a set of permanent teeth only.

Digestion of food takes place in small intestine whereas absorption of water from remaining undigested food takes place in large intestine. Premolars and few molars are not present in milk teeth set.
