Question 1

Which blood pattern is typically associated with a high-velocity impact such as a gunshot wound?

Accepted Answer

Fine mist-like spatter with droplets less than 1 mm

Answer

High-velocity impacts like gunshots produce very fine, mist-like spatter with droplets typically smaller than 1 mm in diameter.

Question 2

What does the term 'manner of death' mean in forensic pathology, and how does it differ from 'cause of death'?

Accepted Answer

Cause of death is the injury or disease that led to death; manner classifies circumstances (homicide, suicide, accident, natural, undetermined)

Answer

Cause of death is the specific injury or disease (e.g., gunshot wound), while manner of death categorizes the circumstances (e.g., homicide or accident).

Question 3

In forensic entomology, which insect is typically the FIRST to colonize a human corpse?

Accepted Answer

Blowfly (Calliphoridae)

Answer

Blowflies are usually the first insects to arrive at a body, often within minutes of death, attracted by gases released during early decomposition.

Question 4

What is 'polymerase chain reaction' (PCR) used for in forensic DNA analysis?

Accepted Answer

Amplifying small amounts of DNA to produce enough for analysis

Answer

PCR amplifies tiny DNA samples exponentially, making it possible to analyze DNA from trace biological evidence that would otherwise be insufficient.

Question 5

Which type of fingerprint is left on a surface by natural skin secretions without any additional substances?

Accepted Answer

Latent fingerprint

Answer

Latent fingerprints are invisible impressions left by sweat and oils from skin, requiring development techniques such as powder or chemical reagents to be visualized.
