Forensic Science And Profiling - Qp4

Explanation
Teeth are made up of a hard substance called enamel, which is the hardest substance in the human body. This makes them highly resistant to wear and tear. Additionally, teeth are designed to withstand the forces of biting and chewing, which further contributes to their durability. Unlike other parts of the human skeleton, such as bones, teeth do not undergo the process of remodeling and are not subject to the same degree of degeneration. Therefore, teeth can be considered the most durable part of the human skeleton.

Explanation
The statement is false because the eruption of teeth is used to assess the age of a child, not a body. Additionally, the eruption of teeth typically occurs during childhood and adolescence, not until the age of 35.

Explanation
An underbite occurs when the lower teeth protrude past the upper teeth. This misalignment of the teeth can be caused by various factors such as genetics, thumb sucking, or jaw abnormalities. It can lead to difficulty in chewing, speech problems, and can also affect the appearance of the face. Treatment options for an underbite include orthodontic braces, jaw surgery, or the use of dental appliances to correct the alignment of the teeth and jaw.

Explanation
During the Salem Witch trials in 1692, there was a case that involved bite marks. This suggests that bite mark evidence has been used in legal cases for a long time, making the statement true.

Explanation
A speculum is indeed a medical tool that is used for examining and investigating body cavities. It is designed to gently separate the walls of a cavity, such as the vagina or the anus, in order to provide a clear view for examination or procedures. By opening up the cavity, healthcare professionals can visually inspect the area, collect samples, or perform various medical interventions. Therefore, the statement "A speculum is a medical tool for investigating body cavities" is true.

Explanation
The statement is false because the case of Anne Marie Burr did not lead to the allowing of dental evidence in British courts. The case of Anne Marie Burr was actually an unsolved missing person case from 1961 in the United States, specifically in Washington state. It is unrelated to the use of dental evidence in British courts.

Explanation
Hair can be easily transferred from one person to another through direct contact or by attaching to clothing. This is because hair tends to stick to surfaces and can easily be carried from one place to another. Therefore, it is considered one of the main contact traces that can be left behind during interactions between individuals.

Explanation
Neutron Assessing Analysis is not a real technique used in forensic science. This technique described in the question is not a recognized or commonly used method for analyzing crime scene evidence. Therefore, the answer is false.
