Amphibians develop special adaptation to live in water and on land. although amphibians spend their early lives in water, they undergo.. a-metamorphosis b-regeneration c-molting to develop .. a-trachea b-lungs c- gills, so that they can survive on land.

The correct answer is A metamorphosis and B lungs.

Amphibians develop special adaptation by which they are compatible of living both on land and in water.

The animals that live on land needs lungs to respire and the animals that live in water needs gills to respire.

The amphibians live in water in the starting days of their life as they have gills later they undergo through metamorphosis in which there is a development of lungs to live on land.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
