This mechanism takes place in the inner ear( organ of corti, supported by basilar membrane.There are  group of receptors in the  Endolymph, whicha are hair cells supported by the tectorial membrane,.The organ of Corti acts as transducers  in  the   inner ear and  converts the circular fluid motion to  electrical signals as action potential, when the hair cells bends against the tectorial membrane as a results of vibration of the endolymph The causes depolarization, and therefore action potential.

The potential is  transmitted to the auditory centres in the brain for sound perceptions.

humans developed antibiotics to fight bacterial infections. however, some antibiotics are no longer effective in killing the bac
andrezito [222]
After a certain period of time, diseases and other sicknesses evolve along with humans, making the antibiotics nearly or completely ineffective. For example, if you took one tylenol when you have a cold, it may not be as effective the next day or so and would need to double the dose. Obviously it will all depend on the illness, and what stage it is in, and the strength of the medication. Also, at one point a vaccine for rabies might need an advanced formula because it might have evolved in animals. The possibilities are endless.
