Question

Frog cannot live without

• A. Cutaneous respiration
• B. Pulmonary respiration
• C. Buccal respiration
• D. All of the above

Answer 1

The correct option is A Cutaneous respiration

While the amphibian is completely submerged, respiration takes place through their skin. The skin has membrane pores through which gases diffuse between the blood vessels and their surroundings. Cutaneous respiration requires constant moisture. When the frog is out of the water, mucus glands in the skin keep the skin moist, which helps absorb dissolved oxygen from the air.
