2. Arrange the pathway of the hearing mechanism in the correct sequence.Susun laluan mekanisma pendengaran berikut dalam urutan yang betul.

A – The oval window transfers sound into the inner ear. Tingkap bujur menghantar bunyi ke telinga dalam

B – Sound is transferred from the eardrum to the ossicles. Bunyi dihantar daripada gegendang telinga ke osikel.

C – Sound vibrations are converted into nerve impulses. Getaran bunyi ditukar kepada impuls saraf.

D – Sound enters the ear canal. Bunyi memasuki salur telinga.

E – The auditory nerve sends the nerve impulses to the brain. Saraf auditori menghantar impuls saraf ke otak.

F – The sound vibrations are magnified. Getaran bunyi dikuatkan.
