The salamander is an amphibian, so it has a as it grows and develops. the adult form is different from the larva because the adult question 1 a)metamorphis b)pupae stage c)simple life cycle question 2 a)breathes through lungs b)forms a pupa c)lives completely underwater

The answer is A……A. Salamanders have a larvae stage that breaths through gills while the adults breaths through lungs.  The larvae stage develops 30 days after hatching and may metamorphose into an adult (60 days from hatching) ore remain as larvae to maturity.

those characteristics are cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development, and adaptation through evolution. some things, such as a virus, demonstrate only a few of these characteristics and are, therefore, not alive
