Two characteristics of amphibians are ____
A
cold-blooded and hatch from eggs
B
warm-blooded and hatch from eggs
C
live birth and moist skin
D
moist skin and warm-blooded
Explanation: 

Detailed explanation-1: -Amphibians breath through their skin, as well as their lungs in some cases. Amphibians are cold-blooded. They have a complex life cycle (larval and adult stages).

Detailed explanation-2: -In typical amphibian development, eggs are laid in water and larvae are adapted to an aquatic lifestyle. Frogs, toads, and newts all hatch from the eggs as larvae with external gills but it will take some time for the amphibians to interact outside with pulmonary respiration.

Detailed explanation-3: -In all amphibians, eggs hatch after one to three weeks depending on water temperature. The resulting tadpoles initially live off the yolk that stays with them, but after a few days, they need to feed. Frog and toad tadpoles feed on plant matter, whilst newt tadpoles eat microorganisms like freshwater plankton.

Detailed explanation-4: -What are the 7 main characteristics of amphibians? Amphibians have a backbone, are cold-blooded, need a moist place to live, can breathe air through their skin, externally fertilize their eggs, eat meat, and grow legs when they mature.
