Which statement is true?

Question

Quizplus · Accepted Answer

Hemipenes, which are paired copulatory organs, occur in male snakes and lizards. Therefore, statement D is true.

Statement A is false because monotremes, such as platypuses, lay eggs, and some species of marsupials give birth to underdeveloped young that complete their development externally, much like an egg-laying animal.

Statement B is false because most male birds lack a penis entirely. Instead, they have a cloaca, which is the opening through which both waste and reproductive fluids pass.

Statement C is false, as amniote eggs have a hard shell that prevents drying out on land but also limits gas exchange. Therefore, the survival of amniote eggs may vary depending on the environment in which they are laid.

Statement E is false because some reptiles are members of viviparous species or have ovoviviparous reproduction, meaning that the embryos develop inside the body of the mother, and the young are born alive.
