Questions: Question 10 1 pts The value of evidence is directly affected by what happens immediately following the crime. Evidence in an unprotected crime scene will degrade, diminish, or disappear over time unless collected and preserved. occurs when items touch one another? contamination cross contamination exposure decontamination Question 11 1 pts As it relates to evidence - extremely small items such as hair or fibers, are a subset of direct evidence called? Trace evidence

The answer is the second one (cross contamination): occurs when items touch one another.

Explanation for each option:

• Contamination: This generally refers to the introduction of foreign substances or elements to the evidence, but it does not specifically imply the interaction between two items.
• Cross contamination: This is the correct term for when items touch one another and transfer material between them, which can compromise the integrity of the evidence.
• Exposure: This term usually refers to the evidence being subjected to environmental factors, such as air, light, or moisture, which can degrade it over time.
• Decontamination: This refers to the process of removing contaminants from an item or area, not the interaction between items.

For Question 11: The answer is Trace evidence.

Explanation:

• Trace evidence refers to extremely small items such as hair, fibers, or other microscopic materials that can be transferred from one location to another and can be used to link a suspect to a crime scene. This type of evidence is a subset of physical evidence and can be crucial in forensic investigations.

Summary: Question 10: The answer is cross contamination. Question 11: The answer is Trace evidence.
