Thermoregulation | MCQs

Explanation

Vertebrates are divided into two main groups based on temperature regulation:

1. Cold-blooded (ectothermic) vertebrates, which include: Fish, Amphibians and Reptiles
2. Warm-blooded (endothermic) vertebrates, which include: Birds and Mammals (including humans)

Explanation

• Elephants have large ears that help them to control their body temperature. 
• The ears are made up of thin skin and have many blood vessels close to the surface, which allows them to release excess heat.
• By flapping their ears, elephants can create a breeze that helps to cool themselves down.
