Answer:
Human beings and large numbers of animals have vocal cords in their voice boxes for producing sounds. Except giraffe.
Explanation:
Humans have vocal cords attached to the bones in the throat. When air passes over these cords, they vibrate back and forth producing sound. Many marine mammals make sound by vibrating elastic ligaments in the larynx. Passing air across these ligaments makes vibrations.
