Homeothermic animals are
A) Toad
B) Lizard
C) Rabbit
D) Frog
Solution
The term homeothermic refers to the warm-blooded animals which have constant and relatively higher temperature. They are animals which can maintain their internal body temperature.
Complete answer:
Homeothermic animals are warm-blooded and maintain a constant body temperature, for example birds and mammals. Let us analyze each option to find out the correct answer.
Option A: Toad belongs to the order Anura of phylum amphibians. Toads are ectothermic animals, found in a warm environment. Other characteristic features include the body is divided into head and trunk, the tail may or may not be present, the skin is smooth and rough without any scales, but with glands that make it moist. Therefore, this is an incorrect option.
Option B: Lizard is part of a group of animals known as reptiles. Reptiles are ectothermic or cold-blooded, which means they cannot control their own body temperature. Other characteristic features include having a backbone, which means they are vertebrates, they produce eggs. Therefore, this is an incorrect option.
Option C: Homeothermic animals are warm-blooded and maintain a constant body temperature for example birds and mammals. Rabbit is a mammal. Mammals have four limbs and produce amniotic eggs. The mammal class is defined by the presence of mammary glands and hair. Therefore, this is the correct option.
Option D: Frog belongs to the order Anura of phylum amphibians. Toads are ectothermic animals, found in a warm environment. Other characteristic features include the body is divided into head and trunk, the tail may or may not be present, the skin is smooth and rough without any scales, but with glands that make it moist. Therefore, this is an incorrect option.
Thus, the correct answer is option (C) Rabbit.
Note: Please do not get confused between the two terms - Homeothermic and poikilothermic. An easy way to not get confused is homo means ‘same’, thus, the term homothermic means animals with ‘same/constant’ internal temperature regardless of the outer environment. Poikilotherms mean cold blooded animals and they cannot regulate their internal body temperature.
