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
D Anand and Meetu only


Ans 1:

Class : Class 7
nknnnk

Ans 2:

Class : Class 5

Ans 3:

Class : Class 8
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.

Ans 4:

Class : Class 9
all are wrong

Ans 5:

Class : Class 4
All are wrong

Ans 6:

Class : Class 6
Rajesh and Anand are wrong I emphasis more about Anand because the tough material in the teeth is it's enamel not the dentine.

Ans 7:

Class : Class 6
Everyone's statements look wrong but the option is not there . Correct answer- {E} all are wrong

Ans 8:

Class : Class 4
ans is B

Ans 9:

Class : Class 7
All the teeth have root,crown,neck but their SHAPE is different so Anand is correct.

Ans 10: (Master Answer)

Class : Class 1
The correct answer is C.

Ans 11:

lllllllllllllllllllllllllllllllllllllllll

Ans 15:

Class : Class 7
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.

Ans 16:

Class : Class 8
why c

Ans 17:

Class : Class 8
I think the question is wronghow can digestion occur if there is no small intestine? so ans is D

Ans 18:

Class : Class 6
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 19:

Class : Class 4
teeth are made of tough material called enamel .

Ans 20:

Class : Class 6
the answer is not A nor B,C or D

Ans 21:

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

Ans 22:

Class : Class 8
c easy

Ans 23:

Class : Class 7

Ans 24:

Class : Class 5
Answer: option C

Ans 25:

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.
C When we eat too much of Z, it gets stored in our body as body fat.
D All of these
