At noon, a female corpse was found partially submerged on the shore of a lake. The air temperature was 26.7 ˚C (80 ˚F), and the water temperature was about 15.6 ˚C (60 ˚F). Rigor mortis was not evident, and the body’s temperature was 15.6 ˚C. Livor mortis showed noticeable reddening on the victim’s back that did not disappear when pressed. Her lungs were filled with water.

this would be a math

well first you need the sample of the temperature and gas level. i couldnt write a hypothesis unless i had some data. i think temperature changes will effect volumes of gas because gas changed into a solid or liquid at specific temperatures.

essentially, one bacterial cell splits into two daugurer cells. bacterial offspring don't need or get care from their parents because they are in a sense their own parents. that said, some bacteria can and do depend on other bacteria especially in harsh environments such as bacterial microfilms in hot water tanks.
