2) Teeth
3) Salivary glands
4) Epiglottis

Answer 1

The tongue lies on the floor of the mouth and is covered with mucous membrane. It is responsible for taste, speech, and manipulating food during chewing and swallowing.

Step-by-step explanation:

1) Tongue. The structure that lies on the floor of the mouth and is covered with mucous membrane is the tongue. The tongue is a muscular organ composed of skeletal muscle and is involved in various functions such as taste, mastication, speech, and swallowing. The mucous membrane covering the tongue contains numerous papillae, taste buds, and small salivary glands. These structures contribute to the tongue's sensory and motor functions. The tongue's movements are crucial for manipulating food during chewing and facilitating the formation of a bolus for swallowing. Additionally, taste receptors on the tongue play a role in the perception of different flavors.
