Answer 2

## Step 1The first question is about the type of evidence that is considered when a physical transfer occurs. The correct answer is "Direct evidence". This is because direct evidence is evidence that directly links a person to a crime without any inference.## Step 2The second question is about what exchange implies in the context of forensic science. The correct answer is "Blood spatter transferred from person to person". This is because exchange in forensic science refers to the transfer of evidence from one person to another.## Step 3The third question is about the importance of separating witnesses at a crime scene. The correct answer is "Prevent contamination of evidence". This is because separating witnesses helps to prevent them from influencing each other's statements, which could lead to contamination of evidence.## Step 4The fourth question is about the definition of a secondary crime scene. The correct answer is "Secondary crime scene". This is because a secondary crime scene is a place where evidence may be found but was not where the crime initially happened.## Step 5The fifth question is about the type of protein that makes hair both strong and flexible. The correct answer is "Keratin". This is because keratin is a type of protein made up of a chain of amino acids that makes hair both strong and flexible.## Step 6The sixth question is about the classification of hair in forensic science. The correct answer is "Individual evidence". This is because hair can be considered individual evidence because it can be unique to a person.## Step 7The seventh question is about the microscopic characteristics of hair. The correct answer is "All of these choices". This is because all the given options are microscopic characteristics of hair.## Step 8The eighth question is about the types of toxins that can be detected in hair. The correct answer is "All of these choices". This is because all the given options are types of toxins that can be detected in hair.
