Forensic Science Fundamentals in Criminal Justice Midterm Quiz

1. What is a Tented Arch?

An arch that starts on one side of the finger and ends on the opposite side.

A loop fingerprint pattern that forms circular ridges.

A fingerprint pattern that spirals from the center outwards.

A tented arch is a fingerprint pattern that is similar to a plain arch, but with a slightly different flow from one side of the finger to the other. It does not spiral outwards or end on the opposite side like a loop pattern.

Explanation

A tented arch is a fingerprint pattern that is similar to a plain arch, but with a slightly different flow from one side of the finger to the other. It does not spiral outwards or end on the opposite side like a loop pattern.

2. What do Double Loop Whorls consist of?

Consist of three separate loop formations.

Consist of a combination of loop and arch formations.

Consist of two separate and distinct loop formations.

Consist of a single circular loop.

A Double Loop Whorl is a type of fingerprint pattern that consists of two separate and distinct loop formations.

Explanation

A Double Loop Whorl is a type of fingerprint pattern that consists of two separate and distinct loop formations.

3. What is a latent print?

Impressions made by animals in the wild

Impressions produced by the ridged skin, on human fingers, palms, and soles of the feet.

A type of print that is visible to the naked eye

A type of print used in 3D printing

Latent prints are not visible to the naked eye and require special techniques like dusting or chemical development to reveal them.

Explanation

Latent prints are not visible to the naked eye and require special techniques like dusting or chemical development to reveal them.

4. What is a plastic print?

A type of printed document made from recycled plastic materials.

A type of fingerprint obtained from plastic surfaces.

A printing technique using plastic molds for mass production of products.

Three-dimensional impressions and can be made by pressing your fingers in fresh paint, wax, soap, or tar.

5. What characteristic is described by the term 'Arch' in forensic science?

A specialized tool used to measure shoe impressions.

The process of analyzing footprints left at a crime scene.

A type of fingerprint pattern that forms a circular or oval shape.

In forensic science, an 'Arch' refers to the pattern of fingerprint ridges that flow or tend to flow out one side of the impression with a rise or wave in the center.

Explanation

In forensic science, an 'Arch' refers to the pattern of fingerprint ridges that flow or tend to flow out one side of the impression with a rise or wave in the center.

6. What is a loop in dermatoglyphics analysis?

A loop involves ridges that intersect and create a circular shape within the fingerprint pattern.

A loop occurs when there are two deltas in the fingerprint pattern.

A loop is formed when the ridges form a continuous wavy pattern from one end to the other.

A loop in dermatoglyphics analysis refers to a specific pattern of ridges that follow a particular flow within the fingerprint. It is characterized by ridges that enter and exit on the same side after recurving or passing through an imaginary line drawn from the delta to the core, with only one delta present in the pattern.

Explanation

A loop in dermatoglyphics analysis refers to a specific pattern of ridges that follow a particular flow within the fingerprint. It is characterized by ridges that enter and exit on the same side after recurving or passing through an imaginary line drawn from the delta to the core, with only one delta present in the pattern.

7. What does an ulnar loop point to?

The THUMB side of a hand.

The BACK side of a hand.

Points to the PINKY side of a hand.

The PALM side of a hand.

An ulnar loop is a type of fingerprint pattern that points towards the pinky side of a hand. It is one of the three main fingerprint patterns along with arches and whorls.

Explanation

An ulnar loop is a type of fingerprint pattern that points towards the pinky side of a hand. It is one of the three main fingerprint patterns along with arches and whorls.

8. What direction does a Radial Loop point to on a hand?

Points to the pinky side of a hand.

Points to the THUMB side of a hand.

Points to the index finger side of a hand.

Points to the back of the hand.

A Radial Loop points towards the thumb side of a hand, which is a characteristic feature in fingerprint analysis.

Explanation

A Radial Loop points towards the thumb side of a hand, which is a characteristic feature in fingerprint analysis.

9. What feature does a whorl fingerprint pattern contain?

Contains loops and tented arches.

Contains only one delta.

Contains 2 or more deltas.

Has no deltas present.

A whorl fingerprint pattern is characterized by having 2 or more deltas, which are ridge formations that diverge or split on a fingerprint. This distinguishes it from other fingerprint patterns such as loops and tented arches.

Explanation

A whorl fingerprint pattern is characterized by having 2 or more deltas, which are ridge formations that diverge or split on a fingerprint. This distinguishes it from other fingerprint patterns such as loops and tented arches.

10. What is visible print?

Are prints that are invisible to the naked eye and require special light to be visible.

Are left in some medium, like blood, dirt, ink or grease, that reveals them to the naked eye.

Are prints that are only visible under ultraviolet light.

Are prints that can only be seen with a magnifying glass.

Visible prints are those that are left in substances that render them naked to the eye without the need for special equipment or lighting.

Explanation

Visible prints are those that are left in substances that render them naked to the eye without the need for special equipment or lighting.
