[28] Cold and Heat Acclimation and Acclimatization

Question 1

What is cold acclimation?

Answer 1

Cold acclimation refers to physiological changes that organisms undergo to adapt to cold temperatures, often involving the increase in heat production or insulation.

Question 2

What is heat acclimation?

Answer 2

Heat acclimation refers to the physiological adjustments made by organisms to cope with high temperatures, such as increased sweat production or changes in blood circulation.

Question 3

How does cold acclimatization differ from cold acclimation?

Answer 3

Cold acclimatization typically refers to long-term adaptations to cold environments that occur over a lifetime or multiple generations, while cold acclimation usually refers to shorter-term adjustments that occur within the lifetime of an individual.

Question 4

What is the difference between heat acclimatization and heat acclimation?

Answer 4

Heat acclimatization refers to long-term adaptations to hot environments over a lifetime or multiple generations, while heat acclimation refers to short-term adjustments within an individual’s lifetime.

Question 5

Give examples of physiological changes in cold acclimation and acclimatization.

Answer 5

• Increased metabolic rate
• Enhanced thermogenesis
• Improved insulation through fat storage or fur density

Question 6

Give examples of physiological changes in heat acclimation and acclimatization.

Answer 6

• Enhanced sweating mechanism
• Altered blood circulation to dissipate heat
• Adaptations to reduce metabolic heat production
