Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following factors affect the rate of decay?
A
Depth of burial
B
Temperature
C
Access by insects
D
None of the above
Explanation: 

Detailed explanation-1: -Like all poikilotherms, the biochemical and physiological processes of insects depend on body temperature, and ambient environmental temperature has a profound effect on the metabolic rate and growth of insects.

Detailed explanation-2: -Temperatures collected from animals showed the presence of feeding larvae increased intra-abdominal temperatures to >5°C above ambient. The findings support the assertion that insect presence is the primary agent affecting decomposition rate via tissue consumption and also the heat they generate.

Detailed explanation-3: -Such factors can be abiotic (soil pH, soil temperature, soil type and moisture) or biotic (environmental microbial communities and insect colonizer accessibility)2.

Detailed explanation-4: -Several of the most frequent factors affecting PMI estimates such as temperature, burial depth and access of the body to insects are fully reviewed. On account of their activity and world wide distribution, Diptera are the insects of greatest forensic interest.
