Question

if you block nostrils of a frog will it survive on land or in water

Answer 1

yes, it will live in water.

Answer 2

yes !

As , Frogs start their lives as aquatic tadpoles with gills to breathe. Tadpoles grow into frogs, lungs replace the gills and allow frogs to breathe on land. Frogs' skin is covered by a layer of slime that dissolves oxygen from air and water. Numerous blood vessels present in frogs' thin skin absorb the oxygen.
