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.
Which of these friends made an INCORRECT statement?

A Anand only
B Rajesh only
C Rajesh and Meetu only

Ans 16:

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.

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.

People who do a lot of physical work, such as labourers, need to eat more of X. Y builds our muscles and helps us grow. Y is therefore known as body-building food. Z gives us more energy than X.
Read the given passage and select the correct option regarding the food nutrients X, Y and Z.

A Fruits have simple X and hence are digested quickly whereas wheat, corn, rice, potato, etc. have complex X and hence take more time to get digested.
B Y helps to repair damaged and hurt body parts.
