Answer :
The subject of the question is understanding the critical limits of body temperature beyond which the human body cannot survive.
When discussing body temperature, it's important to distinguish between normal and extreme temperatures. The normal human body temperature is approximately 37°C (98.6°F), but it can vary slightly depending on the individual and the time of day.
In the context of the options provided:
A. 44 to 46°C
B. 30 to 32°C
C. 39 to 41°C
D. 35 to 37°C
The correct choice is A. 44 to 46°C. Prolonged exposure to particularly high body temperatures, such as those in this range, can lead to heat stroke or hyperthermia. Heat stroke is a condition characterized by failure of the body’s temperature-regulating mechanisms, leading to an inability to dissipate heat. When the body temperature rises to 44 to 46°C (111.2 to 114.8°F), it can result in cellular damage, organ failure, and ultimately death if not treated immediately.
Body temperature regulation is vital for maintaining metabolic processes. If the temperature rises beyond a certain threshold, enzymes and proteins in the body can become denatured, leading to irreversible damage. This is why keeping the body temperature within a safe range is crucial.
In the other options:
- B. 30 to 32°C represents a dangerously low temperature, potentially indicating hypothermia.
- C. 39 to 41°C is a high fever range that could cause serious symptoms but not immediate death.
- D. 35 to 37°C is a typical range for normal body temperature.
Understanding these ranges is important for recognizing and responding to potentially life-threatening conditions. In emergencies, such as heatstroke, immediate medical intervention is critical to prevent serious outcomes.
