Current Question (ID: 13658)

Question:

Adult frog (Rana tigrina) cannot respire through

Options:

1. Moist skin
2. Lungs
3. Gills
4. Buccal cavity

Solution:

Frogs are amphibians that undergo a metamorphosis from an aquatic, gill-breathing tadpole to an air-breathing adult frog. Adult frogs have lungs and respire primarily through their skin and lungs. However, they do not have gills in their adult form, and therefore cannot respire through gills. Option 1, moist skin, is a characteristic of amphibians that allows for cutaneous respiration. Option 2, lungs, is the primary respiratory organ in adult frogs, and option 4, buccal cavity, is used in ventilation, but not gas exchange.
