Which condition favors mummification over putrefaction?

• A. Moist conditions
• B. High humidity
• C. Warm, humid conditions
• D. Dry conditions

Answer: (D)

Dry conditions promote desiccation of the body's tissues, reducing water activity to levels that slow or halt microbial decay. Bacteria and fungi need moisture to grow and carry out the enzymatic processes that drive decomposition; when water is scarce, those microbes can’t proliferate effectively, so the tissues dry out into a preserved, mummy-like state. In contrast, warmth combined with moisture accelerates putrefaction by fueling microbial metabolism and enzymatic breakdown. Therefore, the condition that favors mummification over putrefaction is dryness.
