Final answer:
The condition in which the body stops shivering and has a temperature below 90 degrees Fahrenheit is most likely hypothermia, a life-threatening state of abnormally low body temperature.
Step-by-step explanation:
If the body no longer shivers and the body temperature is below 90 degrees Fahrenheit (32 degrees Celsius), the condition is most likely hypothermia. Hypothermia is a dangerous decrease in core body temperature below 34.4 degrees Celsius (94 degrees Fahrenheit), which can lead to vital processes in the body shutting down. The body initially responds to cold by shivering, which generates heat. However, once the energy reserves are depleted and the body is unable to maintain its core temperature, shivering stops, and the risk of life-threatening conditions increases, including the possible loss of consciousness and death. The hypothesis that when a body stops shivering and the temperature drops below 90 degrees Fahrenheit indicating hypothermia is a logical answer to a scientific question that can be confirmed through scientific investigation.
