b pharynx, larynx, trachea, bronchi, bronchioles, alveoli
c pharynx, larynx, trachea, alveoli, bronchioles, bronchi
d larynx, pharynx, trachea, bronchi, bronchioles, alveoli

Explanation:

• Question 1: True vocal cords (also known as vocal folds) vibrate when air passes through them, producing sound. False vocal cords do not play a role in sound - production.
• Question 12: The correct order of respiratory organs for air passage is: air enters through the pharynx, then goes to the larynx, then to the trachea. From the trachea, it moves to the bronchi (main branches), then to the bronchioles (smaller branches), and finally to the alveoli (where gas exchange occurs).

Answer:

• Question 1: A. True vocal chords
• Question 12: B. Pharynx, larynx, trachea, bronchi, bronchioles, alveoli
