The answer is:-

Frogs have dual mode of breathing which are:-

1.Gills or muscle gland:-frog may also breathe inside water because they have a muscle gland or Gill which also helps them to be moist even if they come out of water.

2.Lungs:- Frogs have lungs for breathing because they come out from water in that case they can't use their gills there .So to breathe outside of water frogs have lungs like humans.

Answer 2

When the frog is out of the water, mucus glands in the skin keep the frogmoist, which helps absorb dissolved oxygen from the air. A frog may alsobreathe much like a human, by taking air in through their nostrils and down into their lungs.
