Which of the following best characterizes fibers, such as nylon, rayon, and polyester?
Who discovered the exchange principle that explain the inevitable transfer of trace evidence materials when two objects or individuals come in to contact?
Which term describes minute, often microscopic forms of evidence that can be collected scientifically analyzed to reconstruct events at a crime scene, either physical or circumstantial?
Which term best describes a material or device capable of producing a rapid, self propagating release of energy resulting in an explosion?
Which term refers to the microscopic particulate material expelled during the discharge of a firearm, often deposited on the shooter's hands, clothing, or nearby surfaces?
Which type of liquid applied coating dries into a thin, pigmented film and can be forensically analyzed to compare layer structure, color and chemical composition?
Which category of forensics material includes skin cells, blood, saliva, pollen, and other microscopic matter?
Which is a transparent, non crystalline material can be examined to determine its source and fracture characteristics, including break patterns?
Which forensic term refers to the distinctive impressions, striations, or damage patterns produced when a tool such as a hammer used on a door or a screwdriver manipulating a lock.
Which term best describes an inorganic material produced through the weathering and breakdown of rock and material sources that can match evidence at a crime scene to a particular type of region
Which type of microscope has more than one lens and is designed to examine trace evidence?
Which type of microscope uses a focused beam of electrons rather than light to generate a highly magnified image with strong surface detail and an apparent three-dimensional topography to enhance trace evidence?
Which analytical laboratory technique separates a complex into its individual chemical components based on differences in of molecular properties to identify trace evidence such as explosives or accelerant residue in an arson investigation?
Which structural, fibrous protein serves as the primary building block of hair, the outer layer of skin, and nails?
Which anatomical structure is defined as the narrow, tube like invagination of the skin that houses the hair root and bulb and determines whether a hair was naturally shed or forcibly removed?
Which term refers to the portion of the hair located within the follicle beneath the skin's surface, and is likely to hold nuclear DNA evidence
Which anatomical layer of hair forms the outermost protective covering mode of overlapping scales; may vary in types of scale, thickness, and pigmentation?
Which hair structure is the protein dense layer surrounding the medulla that contains much of the hair's pigment; one of the most informative features for identifying similarities and differences among human hairs?
Which anatomical feature of hair is the central core that may be continuous, fragmented, or entirely absent in some samples & varies depending on the species
Which term best describes any material item or observable trace that can demonstrate that a crime occurred and/or establish an association between the offense, the victim, the scene, and a potential perpetrator?
Which category of evidence relies on inference rather than firsthand observation; trace evidence present at a crime scene while still falling short of constituting direct proof of guilt on its own?
Which term best describes a naturally occurring fiber obtained by harvesting material from animal, plant, or mineral sources?
How does Locard's exchange principle explain the bidirectional transfer of trace materials between a suspect and a victim, such as hair and fiber, and microscopic particulate matter?
Which plant derived fiber remains the most widely used in modern textiles today?
Which animal derived fiber remains the most widely used in modern textiles today?
