Frog Skin Adaptations and Functions — NEET Biology
📚 Practice ConceptHave you ever touched the skin of frog? The skin is smooth and slippery due to the presence of mucus. The skin is always maintained in a moist condition. The colour of dorsal side of body is generally olive green with dark irregular spots. On the ventral side the skin is uniformly pale yellow. The frog never drinks water but absorb it through the skin.
Which of the following statements regarding the morphology and physiology of a frog are correct? S1: Webbed digits on hind limbs are primarily adaptations for efficient swimming in water. S2: During aestivation and hibernation, frogs solely rely on pulmonary respiration for gaseous exchange. S3: The skin of a frog is always maintained moist due to mucus glands and is crucial for absorbing water, but not for drinking. S4: Male frogs possess sound-producing vocal sacs and copulatory pads on the first digit of the fore limbs, which are absent in females. S5: Frogs are homeothermic animals, meaning their body temperature remains constant despite environmental variations.
