Animals that do not allow their body temperature to vary with the ambient are called?...

Explanation

This Biology question is asking about animals that do not change their body temperature with their surroundings. These animals are called either poikilothermic or homoiothermic. Poikilothermic animals are those whose body temperature changes with the temperature of their surroundings, while homoiothermic animals maintain a constant body temperature regardless of the temperature of their surroundings. The correct answer to this question is option A, homoiothermic. Homoiothermic animals, also known as endothermic animals, are able to maintain a constant body temperature through internal thermoregulation mechanisms such as sweating, panting, shivering, or adjusting their metabolic rate. This allows them to live in various environments and climates without their internal temperature being affected. Some examples of homoiothermic animals include mammals and birds. On the other hand, poikilothermic animals, also known as ectothermic animals, rely on external factors such as sunlight or shade to regulate their body temperature. Their body temperature fluctuates along with the temperature of their surroundings. Some examples of poikilothermic animals include reptiles, amphibians, and fish. In summary, animals that do not allow their body temperature to vary with the ambient are called homoiothermic or endothermic animals, and they are able to maintain a constant body temperature through internal thermoregulation mechanisms. The correct answer to this question is option A, homoiothermic.
