Rats do not contain a gallbladder.

Explanation:
Rats lack a gallbladder, so the statement is correct. In these animals, bile is produced by the liver and drains directly into the intestine via the bile ducts rather than being stored and concentrated in a gallbladder. The absence of a gallbladder means there is no cystic duct, and bile isn’t stored between meals. This is a well-established anatomical feature in rats (and many other rodents), and it matters for understanding biliary physiology and how bile-related processes are studied in these animals.
