Answer:
The semicircular canals ( vestibular system)
Explanation:
The inner ear of humans is made up of two parts.
- The cochlea which aid in the hearing process.
- The vestibular system which aid for balance of the body
The vestibular system comprises of three fluid filled looped canals . The vestibular system comprises of sensory cells which detect even a slight tilting of the head. The fluid filled canals are termed as the semicircular canals. It is due to the vestibular system that we feel a room to bespinning even after we have finished our rotation ride.

Then they leave the cell.
The sodium diverts in the cell layer have receptor locales for acetylcholine.
Reproductive isolation. Species refer to the group of organisms which share common morphological features and can interbreed and produce a viable offspring. Thus, the organisms of one species are reproductively isolated from the organisms of other species
A good extraction solvent should have a strong solubilizing capability for the compound of interest, it should be immiscible or only weakly misciblewith the matrix solvent ( the first solution or mixture containing the compound from its natural source, e.g., water/ether. water/ chloroform, etc. If possible the extraction solvent should be non-flammable, non-toxic or of low toxicity, reasonably volatile, and of low eco-impact. Inexpensive and available, of high purity , and shelf stable. If one is determining the compound of interest by UV/Vis spectrophotometry or fluorescence, the solvent should have extremely low absobance or emission at the wavelength of analysis
• high solubility for the solute and low solubility for the carrier liquid.
• density difference vs. the carrier liquid greater than 150 kg/m. ...
• mid-level interfacial tension (5–30 dyne/cm)
• high resistance to thermal degradation.
