Question

In which animal body temperature is regulated by its tongue?
A. Rabbit
B. Dog
C. Man
D. Cow

Answer 1

Hint: This animal is considered as the best friend of man and is very loyal to its owner. Also, you can see that this animal whenever it is doing nothing it takes out its tongue and starts panting continuously.

Complete answer:
Rabbits are often found in the colder regions and they are mostly covered with hairs which are very soft and the rabbits are very fluffy. Their regulation of body temperature is maintained by the hair present on its body. On the other hand if we see dogs, we can say that not all the dogs have hair on their body and one thing one should always remember that the dogs generally do not have any sweat glands in their body so as to cool down rater their sweat glands are present on their tongue and the perspiration occurs through the tongue only. The third option can be clearly ruled out because we humans have sweat glands in our body spread out evenly and to regulate our body temperature we sweat. The last option we have is of cow and cows can regulate their body temperature in two ways, they can turn the feed they eat into heat energy under the conditions of lower temperature and the other method is they have the ability to regulate the body temperature by the skin and increasing the circulation of blood under the conditions of higher temperature.
The regulation of body temperature is an important part of the body and it is termed as homeostasis. There are other ways also by which other organisms maintain the homeostasis, like bears before the winter season they eat a lot of food and undergo hibernation so that they do not have to be awake and utilize the energy during the winter season.

Hence, the correct answer is option (B).

Note: The mastication of cows again and again to chew its food is for the digestion of food and it is not for the regulation of the body temperature because cows have four stomachs and different mechanisms of digestion.
