Decomposition or rotting is the process by which tissues of a dead organism break down into simpler forms of matter. A dead body that is exposed to the open elements, such as water and air, will decompose more quickly and attract much more insect activity than a body that is buried or confined in special protective gear or artifacts.
Ultimately, the rate of bacterial decomposition acting on the tissue will depend upon the temperature of the surroundings. Colder temperatures decrease the rate of decomposition while warmer temperatures increase it.
Normal body temperature during life is 98.6 degrees F. After death, the body loses heat progressively until it equilibrates with that of the surrounding medium. The rate of this heat loss is approximately 1.5 degrees per hour until the environmental temperature is attained, then it remains stable. Obviously, this measure is greatly effected by location. A body in the snow in Minnesota in January and one in a Louisiana swamp in August will lose heat a widely divergent rates. These factors must be considered in any "estimate" of time of death.
The criminalist who processes the scene should take a body temperature and measure the temperature of the surrounding medium--air, water, snow, earth (if the body is buried). Ideally, the body temperature is taken rectally. Obviously, the sooner after death the body is found, the more accurately time of death can be assessed by this method. Once the body reaches ambient temperature, all bets are off.
What else can I help you with?
An embryo becomes a fetus after?
about 8 weeks of development. At this stage, the major organs have formed and the embryo starts to resemble a human being.
What is an embryo human?
An embryo is the early stage of human development, typically within the first eight weeks after fertilization. During this stage, the cells are rapidly dividing and differentiating to form the various tissues and organs of the body.
How long does it take for human flesh to rot?
The rate at which human flesh rots can vary depending on factors such as environmental conditions, temperature, and presence of bacteria. In general, decomposition of human flesh can begin within days to weeks after death, progressing through several stages of decay over the course of weeks to months.
How long does an embryo take to develop into a fetus?
An embryo typically takes about 8 weeks to develop into a fetus. This period marks the end of the embryonic stage and the beginning of the fetal stage in human development.
How long does the smell of decomposition typically linger?
The smell of decomposition can linger for several weeks to months, depending on various factors such as the environment, temperature, and the size of the organism.
Do dragonflies spend their larval stage on water?
Yes, they do for 2 to 3 weeks!

What is the name given to the human organism two to eight weeks after fertilization and the stage at which the digestive system is formed?
womb
What is the average decomposition time for a banana peel?
The average decomposition time for a banana peel is around 2-4 weeks.
How long can jungles live?
a human can survive in jungle about 4 weeks if you have alot of water you can survive about 7 weeks.
How long is the human repoduction stage?
The human reproduction stage, specifically the gestation period during pregnancy, typically lasts about 40 weeks, or roughly nine months, from the first day of the last menstrual period to childbirth. This period can vary slightly, with full-term pregnancies ranging from 37 to 42 weeks. After birth, the human reproductive stage continues through childhood, adolescence, and into adulthood, but the biological capability for reproduction is generally established during puberty.
Can the average human survive without water for a few days weeks?
Yes
How long does it take for human flesh to rot?
The rate at which human flesh rots can vary depending on factors such as environmental conditions, temperature, and presence of bacteria. In general, decomposition of human flesh can begin within days to weeks after death, progressing through several stages of decay over the course of weeks to months.
What is the average decomposition time for a banana?
The average decomposition time for a banana is around 2-3 weeks, depending on factors like temperature and humidity.
How long does an embryo take to develop into a fetus?
An embryo typically takes about 8 weeks to develop into a fetus. This period marks the end of the embryonic stage and the beginning of the fetal stage in human development.
A dead body that sinks in warm and cold are immersed for how long?
In warm water, a dead body may resurface within a few days to a few weeks due to decomposition gases, while in cold water, the body may remain submerged for a longer period of time, potentially several weeks to months, before resurfacing due to the slower decomposition process. The exact time can vary based on factors such as water temperature, depth, and presence of aquatic life.
