Blood
This is the most common blood type
What is O+
This is the most common fingerprint pattern found in the population.
What is a loop?
This part of the chromatography process moves with the solvent and carries the sample.
What is the mobile phase?
This is the basic element needed to sustain a fire, along with heat and fuel.
what is oxygen?
These patterns, which can be loops, whorls, or arches, are unique to every individual.
What are the three types of fingerprint patterns?
These blood cells carry oxygen throughout the body.
What are red blood cells?
This type of print is left in soft materials like wax or clay.
What is a plastic fingerprint?
Chromatography separates substances based on differences in this property.
What is solubility?
A fire that burns due to the presence of an accelerant typically produces this type of pattern.
What is a pour pattern?
This technique, also known as the “tenprint” method, involves taking impressions of all ten fingers to identify someone.
What is the process of fingerprinting?
This test is used to determine if a stain is blood.
What is the Kastle-Meyer test?
Fingerprint identification relies heavily on these tiny, unique ridge features.
What are minutiae points?
technique is commonly used to separate plant pigments, such as chlorophyll.
What is paper chromatography?
This term refers to the rapid spread of fire due to the simultaneous ignition of all combustibles in a room.
What is flashover?
This is the term for the tiny ridges and details on a fingerprint that can be used for identification.
What are minutiae?
Blood spatter with small droplets typically comes from this type of force.
What is high velocity?
2 deltas
What is a whorl
This type of chromatography uses a column filled with a solid material to separate compounds.
What is column chromatography?
This type of burn pattern is often found on walls near the origin of a fire and can form a V-shape.
What is a V-pattern?
The famous criminal who was identified by his fingerprints in 1911, proving their use in solving crimes.
Who is Thomas Jennings?
This is the point in three-dimensional space where blood spatter originated, determined by analyzing multiple angles of impact.
What is the point of origin?
No deltas
What is an arch
This advanced chromatographic technique is used to separate volatile compounds, often in forensic analysis of accelerants.
What is gas chromatography?
This test can help identify accelerants at a fire scene by analyzing trace evidence from debris.
What is gas chromatography?
This term refers to the comparison of an individual's fingerprints to those in a database to find a match.
What is fingerprint analysis?
