#1
Which of the following is NOT a postmortem change?
Pallor mortis
ExplanationPallor mortis is a pre-mortem change indicating paleness, not a postmortem change.
#2
Which postmortem change refers to the cooling of the body after death?
Algor mortis
ExplanationAlgor mortis refers to the cooling of the body post death.
#3
Which postmortem change involves the relaxation of muscles after death?
Rigor mortis
ExplanationRigor mortis involves muscle stiffening post death.
#4
Which of the following is NOT a stage of decomposition?
Mummification
ExplanationMummification is not a stage of decomposition but rather a preservation process.
#5
Which postmortem change results in the stiffening of muscles after death?
Rigor mortis
ExplanationRigor mortis causes muscle stiffness post death.
#6
Which postmortem change is commonly used to estimate the time of death?
Algor mortis
ExplanationAlgor mortis, the cooling of the body, helps estimate time of death.
#7
Which enzyme is responsible for initiating autolysis during decomposition?
Protease
ExplanationProtease initiates autolysis by breaking down proteins.
#8
Which of the following factors does NOT affect the rate of decomposition?
Cause of death
ExplanationThe cause of death does not affect the rate of decomposition.

Methane
ExplanationMethane is the primary gas produced during early decomposition.
#10
What is the term for the process of insect activity on a corpse?
Entomology
ExplanationEntomology deals with insect activity on a corpse.
#11
What is the term for the breakdown of red blood cells after death?
Hemolysis
ExplanationHemolysis refers to the breakdown of red blood cells after death.
#12
Which of the following factors can accelerate the rate of decomposition?
High humidity
ExplanationHigh humidity accelerates the rate of decomposition.
#13
Which postmortem change results in the settling of blood in the lower parts of the body?
Livor mortis
ExplanationLivor mortis results in the settling of blood in lower body parts due to gravity.
#14
What is the main purpose of estimating the postmortem interval?
To estimate time of death
ExplanationEstimating postmortem interval helps determine the time of death.
#15
What is the primary source of heat loss in a deceased body?
Evaporation
ExplanationEvaporation is the primary source of heat loss in a deceased body.
#16
What role does DNA analysis play in postmortem investigations?
Confirming the deceased's identity
ExplanationDNA analysis confirms the identity of the deceased in postmortem investigations.
#17

ExplanationAltitude has minimal effect on the rate of decomposition.
#18
Which of the following postmortem changes is irreversible?
Decomposition
ExplanationDecomposition, the breakdown of tissues, is irreversible.
