question # 5
multiple choice
thousands of substances are harmful, addictive, and lethal. a confirmation test is needed to determine which toxin is present in a forensic death.
false
true

Explanation:

In forensic science, when dealing with a death where toxins might be involved, there are numerous substances that can be harmful, addictive, or lethal. A confirmation test is essential. Initial screening tests can give a preliminary indication of possible toxins, but they are not always specific enough. Confirmation tests, such as gas chromatography - mass spectrometry (GC - MS) or liquid chromatography - tandem mass spectrometry (LC - MS/MS), are more specific. They can accurately identify the exact toxin present by analyzing the chemical structure and properties of the substance in the biological sample (like blood, urine, or tissue). Without a confirmation test, it would be difficult to precisely determine which of the thousands of potentially harmful substances is the cause of death.

True
