How did you do? 16- Forensic anthropologists study _body decomposition_. 17- Body decomposition is studied in special places called _body farms. 18- Autolysis_ occurs when dead body bells begin to digest themselves. 19- Patterns of livormortis can show how a body _was positioned_ when the person died. 20- Putrefaction is the decay process where _microbes_ feast on a dead body producing gases like CO2, natural gas, and hydrogen sulfide. STINKY! 21- Sulfhemoglobin is _green_ causing dead bodies to turn this color. 22- Dry decay_ can last months or years and happens after maggots have eaten most of the flesh. 23- A body left in a warm, humid environment will decompose much faster_ than normal. 24- How does knowing about decaying bodies help a CSI investigator? Comparing a dead body to known rates of decay and processes can help determine a time of death.
