Question

1. read the title of the graph. rewrite the meaning of the title in your own words.
2. what is the coldest temperature displayed on the graph, and what does it mean?
3. if someones body temperature dropped to 30°c, how long could they survive?
4. think back to a time when you were very cold. how did your body respond?
5. think back to a time when you were very hot. how did your body respond?

Explanation:

1. The title likely refers to a graph showing predicted body - temperature changes over time in a survival situation. It can be rewritten as "Predicted Body Temperature During a Survival Scenario Over Time".
2. The coldest temperature shown on the graph appears to be around the lower - left region, which might be close to the temperature associated with severe hypothermia.
3. Survival time at a body temperature of 30°C depends on various factors like age, health, and presence of insulation. Generally, a person can survive for a few hours to a day or more in this state, but it is a life - threatening condition.
4. When very cold, the body responds by vasoconstriction (narrowing of blood vessels to reduce heat loss from the skin), shivering to generate heat, and hormonal responses to increase metabolism.
5. When very hot, the body responds by vasodilation (widening of blood vessels to release heat from the skin), sweating to cool down through evaporation, and an increase in blood flow to the skin.

Answer:

1. "Predicted Body Temperature During a Survival Scenario Over Time"
2. Temperature associated with severe hypothermia (lower - left region of the graph)
3. A few hours to a day or more, but it is life - threatening.
4. Vasoconstriction, shivering, hormonal responses to increase metabolism.
5. Vasodilation, sweating, increased blood flow to the skin.
