Explanation:

Mammals are vertebrates that have hair or fur, give birth to live young (with some exceptions like monotremes), and nurse their young with milk. Horses, wolves, cats, humans, cows, mice, deer, pigs, and bats all share these mammalian characteristics. Reptiles are cold - blooded, lay eggs (usually with leathery shells), and have scales. Rodents are a subset of mammals characterized by continuously growing incisors, and not all the listed animals are rodents. Primates are a specific order of mammals that includes humans, apes, monkeys, etc., but not all the listed animals (like horses, wolves) are primates.
