Chapter 46, Problem 1IQ
Summary Introduction
To explain: That why don’t all animals have teeth like omnivores, capable of eating anything.
Introduction: A vertebrate is an animal with a spinal cord surrounded by bone or cartilage. Vertebrates include fish, birds, amphibians, mammals, and reptiles. Mammals are vertebrate animals constituting the class Mammalia. Different mammals (carnivore, herbivore, and omnivore) have evolved tooth shapes suited for their diets.

- The two types of digestion that take place in mammals isarrow_forwardUngulates Ungulates, such as deer, reindeer, and elk, are hoofed mammals. These animals have keen hearing, clear vision, supple, well-conditioned muscles, and razor sharp reflexes. The evolution of the four-chambered stomach in ungulates developed as a result of a need to eat quickly in the open and chew later in the safety of cover. This process is called ruminating or "chewing the cud." In other words, ungulates regurgitate and then re- chew their food. Which of the following would be considered a physiological adaptation of ungulates? A) their four-chambered stomach B) their long legs, which help them outrun predators C) their ability to stand perfectly still, which helps them avoid predators D) their ability to hibernate to avoid cold wintersarrow_forwardWhich animal do you think would have the longest intestine/longest digestive time? O A carnivore like a wolf An omnivore like human that eats both plant and animal material O An herbivore that eats only nutrient poor leaves M O A detritivore that eats dead/decaying material like an isopod Parrow_forward
