Monogastric examples.

Monogastric examples.

• A. Cow, Sheep, Goats
• B. Dog, Cat, Pig
• C. Horse, Donkey, Mule
• D. Rabbit, Hamster, Gerbil

Answer: (B)

Monogastric digestion involves a single-chambered stomach where digestion mainly occurs before the small intestine. Dogs and cats have a simple, single-stomach layout typical of carnivores, and pigs also possess a one-chamber stomach as omnivores, so their digestion fits this pattern. In contrast, cows, sheep, and goats are ruminants with a four-compartment stomach designed for rumination and microbial fermentation, while rabbits, hamsters, and gerbils rely on hindgut fermentation in the cecum/colon after the stomach. Therefore, the trio that best represents monogastric examples is dogs, cats, and pigs.
