Acclimatization
In the context of thermoregulation, what do the left and right ends of each bar represent in the diagram?
The ambient temperature at which minimal resting metabolic heat production starts to increase, and mechanisms of heat dissipation are activated
What is the term for the maximum temperature an organism can survive?
