**Brainiest if correct** Write a conclusion to a informative paper about reptile that specifically talks about snakes, lizards, and turtles. This is my family computer so I cannot download file/links, so don't answer with a link.

Reptiles are a group of air-breathing vertebrates that have internal fertilization, amniotic development, and epidermal scales covering part or all of their body. The major groups of living reptiles—the turtles, lizards, and snakes, and crocodiles—account for over 8,700 species.

Most reptiles have a continuous external covering of epidermal scales. Reptile scales contain a unique type of keratin called beta keratin; the scales and interscalar skin also contain alpha keratin.

Keratin is the main component of reptilian scales. Scales may be very small, as in the microscopic tubercular scales of dwarf geckos, or relatively large, as in the body scales of many groups of lizards and snakes. The largest scales are the scutes covering the shell of a turtle or the plates of a crocodile.

(Please tell me if this is wrong, or if I didn't read the question correctly)

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !

the answer is "a.) well–developed vascular system."
