Question

Investigators recognized the importance of analysis of hair as:

1) It can provide information about an individual's drug use history.
2) It can help determine the presence of toxins or poisons in the body.
3) It can be used to identify an individual through DNA analysis.
4) It can indicate the presence of certain diseases or medical conditions.

Answer 1

Hair analysis is important for drug history, toxin detection, DNA identification, and disease indication.

Step-by-step explanation:

Hair analysis is important for several reasons:

1. It can provide information about an individual's drug use history. For example, certain drugs can be detected in the hair follicles for a longer period of time compared to other bodily fluids.
2. It can help determine the presence of toxins or poisons in the body. Many toxins and poisons can accumulate in the hair over time, making it a valuable sample for analysis.
3. It can be used to identify an individual through DNA analysis. Each person's DNA is unique, and hair can be a good source of DNA for identification purposes.
4. It can indicate the presence of certain diseases or medical conditions. Hair analysis can reveal abnormalities or imbalances in certain elements or compounds in the body, which can be indicative of underlying health issues
