8. Assertion (A): Polyphyodont refers to teeth that are constantly replaced throughout life.
Reason (R): This phenomenon is seen in human beings.
- Both (A) and (R) are correct

11. Bite marks help in personal identification using which of these types of evidence?
A. Saliva
B. Lip Prints
C. Teeth Marks
D. DNA
Choose the correct answer from the options given below:
- A, B and C only
- B, C and D only
- A, B and D only
- A, C and D only
Answer and Explanation
Answer: (3) A, C and D only
Explanation: When a bite mark, there is very little chance of getting a legit lip print. Even the lips made to the surface— in that position— lips marks are made by stretched lips that usually result in smudge ridges.
-> Lip prints are the unique patterns and grooves on the lips that can be left behind on surfaces when a person presses their lips against them.
-> However, during a bite, lips do not typically make contact with the bitten surface in a way that leaves a unique print.
-> Lip print: Lip prints are generally less reliable compared to saliva, teeth marks, and DNA for personal identification in bite mark analysis, as they may not be present in every case and can be more easily smudged or distorted.
