College Answer

Many candidates did not read the question carefully and misinterpreted what was being asked. 
Candidates often digressed into a discussion of thermoregulation. Several candidates wrote 
about body's response to cold and heat rather than mechanisms of heat production and loss as 
was asked.
There was confusion between mechanisms of endogenous heat production and measures to 
conserve heat. "Behaviour" only attracted marks in relation to voluntary muscle activity for heat 
production. Changing clothes or seeking a warm environment does not increase heat output by 
the body. Behaviour can reduce heat loss. Many candidates did not specify ambient or core body 
temperature. The definitions of Thermoneutral Zone and Interthreshold Range were not clear. 
Knowledge generally lacked detail and this was most evident when precise definitions were
