The question asks, "In collecting suspected semen on an object, use a tube and transfer it to where?"
Among the options provided:
- Container: This is a commonly used option for securely storing collected biological evidence, including semen, to prevent contamination or degradation.
- Paper pocket: While paper can be used for some types of evidence (e.g., trace evidence), it is less suitable for liquids or semi-liquids due to absorption and risk of loss.
- Cotton cloth: This could introduce contaminants and is not a recommended method for storing biological samples.
- Glass kit: Glass containers may also be used but are less common than standard sealed containers in crime scene investigation.
The most appropriate answer in forensic practices is Container, as it provides secure, contamination-free storage for biological evidence like suspected semen.
