What term describes the type of blood temperature regulation found in insects?

Warm-blooded
Cold-blooded
Variable-blooded
Stable-blooded

The correct answer is: Cold-blooded

The term that describes the type of blood temperature regulation found in insects is indeed "cold-blooded." Insects are classified as ectothermic organisms, meaning they cannot internally regulate their body temperature and rely on external environmental conditions to maintain it. This characteristic allows them to be highly adaptable to various climates, but it also means their activity levels are significantly influenced by the temperature of their surroundings. Unlike warm-blooded (or endothermic) animals, which can maintain a constant internal body temperature regardless of external conditions, insects' metabolic rates and behaviors change with ambient temperatures. Consequently, they may be more active in warmer conditions and less so when it's cold. This distinction emphasizes the significant ecological and physiological adaptations that ectothermic organisms like insects have developed in response to their environments.
