Forensic Science Review for Final Part 2

The type of blood cells that contain the most DNA are:

• white blood cells
• red blood cells
• platelets

The blood cells that contain hemoglobin that reacts with chemicals in many forensic tests are:

• red blood cells
• white blood cells
• platelets
• plasma

Testing to determine the type of blood found at a crime scene is not done much anymore because:

• blood samples are sent for DNA testing instead
• blood type testing is expensive
• blood type testing requires equipment that police don't have access to
• since blood can carry diseases, most police officers choose not to handle it

The chemical shown below that fluoresces when it comes into contact with blood residue is called:

• luminol
• hemastix
• Kastle-Meyer
• hemoglobin

A presumptive blood test is used in order to determine:

• whether or not a substance is blood
• if blood came from a human or an animal
• what type of blood a person has

The database that stores ​information about fingerprints is:

• fingerprint
• IAFIS or AFIS
• DNA
• CODIS

The database that stores ​information about DNA is:

• CODIS

• NIBIN
• AFIS

• NGI

The database that stores ​information about guns is:

• CODIS

• NIBIN
• AFIS

• NGI

The presumptive blood test shown below is:

• Kastle-Meyer test
• Hemastix
• Luminol
• Fluorescein

The blood spatter shown below that resulted from blood dripping from a person's nose can be classified as

• passive blood spatter
• medium velocity spatter
• high velocity spatter
• low velocity spatter
