Answer:
The correct answer is option D, that is, 2,4,6,1,5,3.
Explanation:
With the approaching of sound waves, ear pinna mediates it towards the external auditory canal, this makes sound waves to reach the tympanic membrane. This results in the vibration of the tympanic membrane, and as the malleus, that is, the first ear ossicle, which is attached to the tympanic membrane gets displaced.
This movement of the malleus further moves the stapes and the incus. As the footplate of the stapes is associated with the oval window, the movement of the oval window takes place. This movement of the oval window creates pressure waves in the vestibular duct's perilymph. The movement of these pressure waves takes place from the Oval window to the Round window.
At the time of this movement, the pressure wave distorts the basilar membrane on its path to the round window, resulting in the vibration of the basilar membrane and the hair cells situated in the membrane against the tectorial membrane.
The stimulation of the sensory neurons takes place in the vestibulocochlear nerve's cochlear branch due to the displacement of the stereocilia. Post this, information reaches the auditory cortex in the temporal lobe's superior temporal gyrus, and hearing takes place.
Convergent evolution<span> is the independent </span>evolution<span> of similar features in species of different lineages. Convergent evolution creates </span>analogous structures<span> that have similar form or function but were not present in the last common ancestor of those groups. The </span>cladistic<span> term for the same phenomenon is </span>homoplasy<span>. The </span>recurrent evolution<span> of flight is a classic example, as flying </span>insects<span>, </span>birds<span>, and </span>bats<span> have independently evolved the useful capacity of flight. Functionally similar features that have arisen through convergent evolution are </span>analogous<span>, whereas </span>homologous<span> structures or traits have a common origin but can have dissimilar functions. Bird, bat and </span>pterosaur<span> wings are analogous structures, but their forelimbs are homologous, sharing an ancestral state despite serving different functions.</span>
