The right answer is "Both insects and amphibians exhibit metamorphosis"
Have six legs :
Amphibians are not six legged organisms rather they are four legged
Are both Vertebrates :
Insects belong to the Phyla Arothropoda. Arthropods are invertebrates
Amphibians belong to the Phyla Chordata. Chordates includes vertebrates
Go through Metamorphosis :
Both insects and amphibians are found to exhibit metamorphosis. For instance, Butterfly incase of insects and Frogs incase of Amphibians
Are both Invertebrates :
Insects are Invertebrates while Amphibians are Vertebrates
Look like their parents at birth :
Insects don't resemble their parents at birth. As they grow into adults,they develop body patterns, structures similar to their parents
Amphibians develop indirectly,from larvae. Indirect Development refers to the development where the embryo develops into a sexually - sterile organism after which it undergoes metamorphosis to become an adult.
