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
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 3:
Class : Class 5
the correct answer is c because premolars and molars are a set of permanent teeth only.
Ans 7:
Class : Class 8
I think the question is wronghow can digestion occur if there is no small intestine? so ans is D
Ans 8:
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 11:
Class : Class 8
All the teeth have root,crown,neck but their SHAPE is different so Anand is correct.
Ans 19:
Class : Class 6
Everyone's statements look wrong but the option is not there . Correct answer- {E} all are wrong
Ans 21:
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 23:
Class : Class 7
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 27:
Class : Class 7
C is the correct answer because the solution is like that. So i think it is the correct one !
