Question

list two characters which help amphibians to survive on land.

Answer 1

Transition to life on land meant significant changes to both external and internal features. In order to live on land, amphibians replaced gills with another respiratory organ, the lungs. Other adaptations include:

Skin that prevents loss of water .Eyelids that allow them to adapt to vision outside of the water.An eardrum developed to separate the external ear from the middle ear.A tail that disappears in adulthood(in frogs and toads).

Answer 2

Hope this helps!

1.Amphibians have mucus glands which produce a sticky substance on their skin.

2.They live on land for part of the time and breathe both through their skin and with their lungs as their lungs are not sufficient to provide the necessary amount of oxygen.
