Answer:
Most amphibians can breathe both through cutaneous respiration (through their skin) and buccal pumping - though some also retain gills as adults. Some aquatic salamanders (and all tadpoles) have gills and can breathe underwater thanks to them. The Mexican axolotl, for example, never loses its gills.

Answer:
Helicase
Explanation:
DNA replication is the process in which DNA makes copies of itself.
The process of DNA  replication is supported by several enzymes. 
The initial step of DNA replication is unwinding of double stranded DNA which is catalyzed by helicase enzyme. Helicase enzymes breaks the hydrogen bond between the  DNA strands and prepare them for replication process.
Hence, the correct asnwer is "Helicase".
