The attenuation reflex prevents damage to delicate ear structures.
Explanation:
In attenuation reflex, the muscles of middle air contract involuntarily in response to loud sound in normal healthy auditory system. It also occur when a person start to vocalize.
The loud sound stimuli casues the contraction of tensor temponi and stapedius muscle of ossicles. The tensor temponi tighten the eardrum by stiffening the ossicular chain and stapedius pulls the stirrup away from oval window of cochlea. They make the chain of ossicles more rigid by contracting.
The attenuation reflex decreases the intensity of the loud sound transmitted to internal air by decreasing the vibrational energy to cochlea. Its response is more to lower frequencies than higher frequencies so that we can hear the voice in the place of loud sound.
But still the attenuation reflex does not provide complete protection from loud sounds such as sudden sound can damage cochlea because of delay in attenuation reflex.
The planet is neptune wind currents operate in much wider bands around the planet allowing storm like great dark spots to slowly drift across latitudes.
Answer: There might be more of one kind of flatworm than any other because they adapt more to their enviorment than any worm. OR its because they have more access to resources
