Forensic Science And Profiling - Qp4

1. Hair can be transferred from one person to another, both on the body and clothing, and is one of the main contact traces.

True

False

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.

2. Teeth are the most durable part of the human skeleton.

True

False

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.

3. One of the earliest reordered bite mark cases in the United States of America was during the Salem Witch trials in 1692.

True

False

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.

4. A speculum is a medical tool for investigating body cavities.

True

False

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.

5. The age of a body is assessed by the eruption of the teeth, which continues to the age of 35.

True

False

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.

6. ______ is when the lower teeth protrude past the upper teeth.

Cavities

Periodontitis

Underbite

Tooth decay

Overbite

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.

7. The case of Anne Marie Burr was a landmark case which led to the allowing of dental evidence in British courts.

True

False

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.

8. Match the following statements:

The outer covering, which is composed of overlapping cells that are different for each species of animal.

Each cell will carry identification of the individual.

This is not found in every hair, but is composed of cells and is not continuous throughout the hair shaft, although there are rare exceptions.

Submit

9. Match the following statements:

this is composed primarily of calcium phosphate and is the white outer part of the tooth.

is a layer beneath the enamel and is composed of living cells, which in turn secrete a durable mineral substance.

is the inner living tissue/structure, along with the blood vessels and nerves.

is the connective tissue that holds the roots of each tooth to the gums and the jawbone.

this is tissue that ensures the teeth are held securely to the jaw.

Submit

10. Neutron Assessing Analysis is used by taking a hair sample from the scene of the crime and subjecting it to bombardment with neutrons that are focussed solely on the cell nuclei, which in turn produces radioactive isotopes.

True

False

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.
