The fluid in the cochlea moves in response to vibrations from the oval window. 25,000 nerve endings are set in motion as the fluid moves.
Mechanical vibrations of the stapes footplate at the oval window generate pressure waves in the perilymph of the cochlea's scala vestibuli. These waves travel around the cochlea's tip, through the helicotrema, and into the scala tympani before dissipating as they hit the round window. Sound-induced pressure changes in the cochlea travel down the fluid-filled tympanic and vestibular canals, which are filled with a fluid called perilymph. The membranous oval window functions similarly to a piston in a hydraulic system, pushing and pulling on the enclosed fluid.

Answer:
Humans
Explanation:
A new research now suggests that possibly the entire animal kingdom, including humans, shares important genetic mechanisms with sea sponges. Now published in the journal Science, the discovery has been made by a team of scientists led by Dr. Emily Wong from the Victor Chang Cardiac Research Institute and UNSW Sydney.

answer; Genetic variation is a term used to describe the variation in the DNA sequence in each of our genomes. ... Individuals of a species have similar characteristics but they are rarely identical, the difference between them is called variation. Updated January 06, 2020. A gene is a portion of DNA that determines a trait. A trait is a characteristic, or a feature, passed from one generation to another, like height or eye color. Genes come in multiple forms or versions. Each of these forms is called an allele
