Question

Which of the following pair is unmatched for the animals of Reptilia class?

• A. Cleidoic eggs and temperature constant
• B. Meroblastic cleavage and lack of metamorphosis
• C. 12 pairs cranial nerves and skin rough
• D. Skull monocondylic and skin with scales

Answer 1

The correct option is A Cleidoic eggs and temperature constant

Reptile eggs are cleidoic eggs, which are enclosed in a protective shell limiting the exchange of water, gases, etc. Their temperature does not remains constant and they have to regulate their body temperature by behavioral thermoregulation mechanisms.

Reptiles shows meroblastic cleavage as egg contain a large amount of yolk and they lack metamorphosis.

Higher vertebrates like reptiles have 12 pair of cranial nerves. Reptile skin is covered with scutes or scales and thereby their skin is rough.

Reptile skull is monocondylic and skin is covered with scutes or scales. Therefore, the correct answer is option A.
