A salamander is a vertebrate that spends part of its life cycle in water (juvenile stage) and part on land (adult stage). In both life stages, the salamander's body temperature depends on its surrounding environment, so the salamander demonstrates behavior.

Ectothermic

Explanation:

Ectothermic behavior is a type of behavioral mechanisms adopted by animals to regulate their body temperature by depending on the temperature of their environment or external source. These behavior is exhibited by animals that do not produce heat internally to regulate their body temperature, but rely on the external heat sources to maintain their body temperature, which is vital for the normal functioning of their body.

evidence and logical support is essential for a scientist to do in order to maintain credibility. this is because no one can believe without any logic and without any evidence.hence a scientist can maintain credibility by proving himself and by answering logically so experiments prove very beneficial. logical hypothesis give conclusion which is acceptable. therefore, there are two main factors to maintain credibility by a scientist is evidence and logical support.

hybridization actually occurs frequently in nature. evolution is derived from the process of hybridization that creates things with different traits. this leads to the species changing and evolution occurring. hope this : )
