teeth that are all the same

four - chambered heart

jaw composed of several bones

Explanation:

• Mammals have a dome - shaped, muscular diaphragm which aids in breathing.
• Mammals have a four - chambered heart (two atria and two ventricles) that separates oxygenated and deoxygenated blood.
• Mammals have a well - developed outer brain layer (cerebral cortex) which is important for higher - order brain functions like learning, memory, and sensory perception.
• Mammals have heterodont teeth (different types of teeth like incisors, canines, premolars, and molars), not teeth that are all the same.
• The mammalian jaw is composed of a single bone (the dentary), while in some other vertebrates, the jaw is composed of several bones.

Answer:

dome - shaped, muscular diaphragm, four - chambered heart, well - developed outer brain layer
