well they have to be in a moist environment and wet mud to keep it from drying out.

What adaptations does a reptiles egg have to keep it from dying out?
the shell keeps the egg from drying out by that I mean it keeps it moist or by leaving it it a wet dry area
What adaptations did reptiles receive that amphibians didn't?
Reptiles have developed an outer covering of scales or bony plates to retain their body moisture. Amphibian skin lets water pass in and out so amphibians must stay in or near a water source to keep their bodies from drying out. Amphibians develop from egg to larvae to adult in water. Reptiles do not have a larval stage.
Why do reptiles have hard shelled eggs?
Reptiles have hard-shelled eggs because the shell provides protection and support for the developing embryo. It allows for gas exchange with the environment and prevents the egg from drying out. This adaptation is key for reptiles, as they lay their eggs outside of their bodies.
How do reptiles keep their own egg warm if they are cool blooded?
they dont
What type of animal is thought to have developed after the evolution of an egg that would not dry out on land?
Reptiles are thought to have developed after the evolution of an amniotic egg, which allowed them to reproduce successfully on land without the risk of the egg drying out. This adaptation was a key factor in their ability to transition from an aquatic environment to a terrestrial one.
What allows terrestrial reproduction reptiles have an egg containing?
Most reptiles reproduce sexually although some species reproduce asexually. Upon fertilization, the embryo develops inside an egg with a calcaeous shell. This egg serves to protect the embryo, prevents drying out of the amniotic layer, and allows for efficient gas exchange.
How did the evolution of an amniotic egg help reptiles?
The amniotic egg allowed early reptiles to move away from waterside habitats and colonize dry regions. It allowed reproduction on land by preventing the embryo from drying out, so eggs could be laid away from the water.
Do reptiles lay eggs on land or in a nest?
Some reptiles lay egg in the nest and some reptiles lay egg on the land.
How is the embryo protected inside the egg?
Most reptiles simply abandon their eggs to 'fate' once they're laid. Some species of lizards and snakes will stay close-by and actively discourage anything from disturbing the 'nest'. The majority of animals know instinctively to avoid contact with reptiles.
What is amniote egg?
Reptiles, mammals, and birds lay amniotic eggs, which contain a yolk to nourish the developing organism. Eggs are used to protect the organism as it develops, and the egg also aids in gas and energy exchange.
Is a reptile born or hatched from an egg?
reptiles hatch from an egg
What group evolved from the amphibians with the development of the amniotic egg?
reptiles
