Answer 1

Answer:

Answer 2

Answer:

(a) Only birds and reptiles are oviparous.

Explanation:

• Oviparous animals are animals that lay their eggs. These eggs have little to no embryonic development within the mother.

• This is the reproductive method of most fish, amphibians, most reptiles, and all pterosaurs, dinosaurs, and monotremes.

 The following statements are correct about Oviparity:

• A large amount of yolk provides the nutrients for the developing embryo.
• The shell protects the egg from dehydration.
• Both oxygen and carbon dioxide can diffuse through the shell.​

However, birds and reptiles are not the only oviparous species. A group of mammals (the monotremes) is also egg layers.

For example platypus, and echidna.
