Question

1.which animal is famous for sleeping while standing up? a. domestic cat b. horse c. sloth d. tiger

Explanation:

Horses have a unique anatomical feature called the stay apparatus. This allows them to lock their leg joints in place. As a result, they can sleep while standing up. This is an adaptation that helps them quickly escape from predators. Domestic cats, sloths, and tigers do not typically sleep while standing. Domestic cats usually sleep in more curled - up or lying positions. Sloths are known for their slow movement and hanging from trees. Tigers, like most big cats, sleep in a more relaxed, lying posture.

Answer:

B. Horse
