Question

question 26
which subgroup of mammals raises their young in pouches?
○ eutherians
○ marsupials
○ monotremes
○ cetaceans

Explanation:

• Eutherians: These are placental mammals. The young develop inside the mother's uterus with a well - developed placenta providing nutrients. They do not have pouches for raising young.
• Marsupials: Marsupials are known for giving birth to relatively underdeveloped young. The young then crawl into a pouch (marsupium) on the mother's body, where they continue to develop, feeding on milk.
• Monotremes: Monotremes are egg - laying mammals. They do not have pouches for raising young in the way marsupials do. After laying eggs, they may incubate them (e.g., platypus) or have other forms of care, but no pouch - rearing of live - born young.
• Cetaceans: Cetaceans (whales, dolphins, porpoises) are eutherian mammals. Their young develop inside the mother (with a placenta) and are born relatively well - developed. They nurse their young with milk, but there is no pouch involved in the rearing process.

Answer:

Marsupials
