Which animals are cold-blooded, breathe with lungs, most lay eggs, although in some the eggs hatch inside the female, and have scales or plates?

Reptiles

Explanation:

Reptiles are vertebrate animals that belong to the Animalia Kingdom, Filo Chordata and Reptilia Class. In evolutionary history, reptiles were the first vertebrate animals to conquer the terrestrial environment. Examples of reptiles are turtle, jabuti, tortoise, snake, snake, alligator, crocodile, chameleon, iguana and lizard.

Reptiles are cold-blooded and petilothermal animals, meaning they are unable to maintain their constant body temperature. Thus, they require the heat of the environment to regulate body temperature. They have pulmonary respiration and a thick hard skin with the presence of scales or plaques.

Most reptiles are oviparous. Only a few snakes and lizards are ovoviviparous. The egg has the following embryonic annexes: amnium, chorion, yolk sac and allantoid. Some species allow eggs to still hatch within the female. When puppies are born they resemble adults, as development is straightforward.
