Question Description
Amphibians are the first tetrapods to invade the land. The juvenile phase of the life cycle is dependent on water, where gas exchange occurs through gills. Amphibians have aquatic larval life and terrestrial adult life. Respiration is by gills, lungs and skin. Their body is divisible into head and trunk and skin is moist without scales. The two pairs of limbs are used for locomotion except for caecilians. They are cold blooded animals. Respiration is by gills (in larva), lungs and skin (in adults). Amphibians have a three-chambered heart. Fertilisation is external. However, in Salamander and Ichthyophis fertilization is internal. They are mostly oviparous, except for Salamander, which is viviparous. Development is indirect.Q. In some amphibians even after attaining sexual maturity, larval characters are retained. It is known as _______.a)Phylogenesisb)Neotenyc)Parthenogenesisd)OntogenesisCorrect answer is option 'B'. Can you explain this answer? for NEET 2024 is part of NEET preparation.
