Question

A. Cold blooded
B. Warm blooded
C. Both A and B
D. None of these

Answer 1

Hint: Warm blooded animals are the animals which can maintain a constant body temperature irrespective of the changes in the surrounding. For example birds, mammals. Cold blooded animals are the animals which do not have the ability to retain heat. For example insects, amphibians.

Complete Answer:
To solve this question we must know about the warm blooded or cold blooded animals.
There are two types of animals-
1. Homeothermic- These are the animals which maintain a constant body temperature irrespective of the change in the environmental temperatures. They are able to maintain a steady state by regulating their metabolic activities. This is a defence mechanism to protect the animal from the fungus and other microorganisms. All the birds and mammals are warm blooded animals.
2. Poikilothermic- These are the animals whose internal temperature fluctuates with the change in the environment. The heat generated by the body is lost due to sweating and breathing. They seek sun, shade in order to balance the body temperature. All aquatic animals like fishes, amphibians are cold blooded. Rohu is a species of fish which belongs to the carp family. It is a freshwater fish found in South Asia. As Rohu is a fish so it is a cold blooded animal.

So the correct answer for this question is option A.

Note: Some cold blooded animals like lizards and snakes bathe in the sun in the early morning and go to shade in the noon so as to maintain their body temperature. The poikilothermic animals undergo hibernation in winters to protect themselves from extreme cold.
