Thermoregulation and Adaptive Behaviors — NEET Biology
📚 Practice ConceptThey do not have constant body temperature i.e., their body temperature varies with the temperature of the environment. Such animals are called cold blooded or poikilotherms. You might have also noticed changes in the colour of the frogs while they are in grasses and on dry land. They have the ability to change the colour to hide them from their enemies (camouflage). This protective coloration is called mimicry. You may also know that frogs are not seen during peak summer and winter. During this period they take shelter in deep burrows to protect them from extreme heat and cold. This is known as summer sleep (aestivation) and winter sleep (hibernation) respectively.
Which of the following correctly represents the scientific name, phylum, class, thermoregulation, adaptive colouration, and seasonal behaviour of frogs?
View solution & NCERT explanation
Correct answer: C — Rana tigrina – Phylum Chordata – Class Amphibia – Cold blooded – Protective coloration is mimicry – Summer sleep is aestivation, winter sleep is hibernation
The common Indian frog is Rana tigrina, belonging to phylum Chordata and class Amphibia. Frogs are cold-blooded (poikilotherms). They show colour change to blend with the surroundings (camouflage), which is a form of mimicry. In extreme summers they undergo aestivation (summer sleep), and in extreme winters hibernation (winter sleep). Other options deliberately mix up scientific names, phyla, classes, thermoregulation type, and seasonal behaviour to mislead.
