Final Answer:
False. Dogs are mammals, and snakes are not marsupials; they are reptiles.
Step-by-step explanation:
Dogs and snakes belong to different classes of animals. Dogs are mammals, characterized by giving birth to live young ones and nourishing them with milk. In contrast, snakes are reptiles, a class that includes animals like lizards and turtles. Reptiles lay eggs, and they are characterized by scales and a cold-blooded metabolism.
The statement is false because it incorrectly asserts that snakes are marsupials. Marsupials, like kangaroos and koalas, are a distinct group of mammals that give birth to relatively undeveloped live young, which then continue to develop in a pouch. It's crucial to understand the classifications within the animal kingdom to accurately categorize different species.
