yes
no, they all require heat
Reptiles are all Heterotrophs. All breath air, All have scales, Almost all lay eggs (Boa Constrictors and Rattle Snakes give live birth) All need heat to be active, All are cold-blooded.
Alligators are reptiles.. they are cold-blooded, and need the sun for its heat.
Since lizards are reptiles, they are cold blooded and need heat to survive.
Because they can generate their own body heat - reptiles cannot and need a warm environment
There is no answer for this question as it all depends on what animal your talking about. Dogs and cats need more heat then reptiles do for example
Bearded dragons need the sun alot because they are reptiles.Reptiles are cold blooded and cold blooded reptiles dont produce their own body heat unlike us, humans(humans are warm blooded so we dont need to stand in the sun all day like reptiles).So all reptiles including the Bearded dragon get their warmth from the sun.
Salamanders are Poikilothermic. This means that their body temperature is determined by their environment.
Reptiles can't keep warm all by themselves. They are ectothermic which meens they are cold blooded. That meens that they need the sun or somthing elses heat to keep warm. Whatever their surrounding climates temperature is is what the reptiles temperature is. They will lose energy and may die in the cold.
reptiles are made of scale,scute,or shell and all reptile are cold-blooded(you can see their cold-blooded because they need to bask on heat source to gain heat) and most reptile don't care for their young and most reptiles don't give birth to live young
Reptiles are animals. All animals in full activity need cellular respiration and all vertebrates I know of do that by means of circulation. Reptiles do circulate blood in their systems.
Reptiles are cold-blooded vertebrates that have scales or scutes covering their bodies. They lay eggs on land and breathe air through lungs. Reptiles are ectothermic, meaning they rely on external sources of heat to regulate their body temperature.
