They may be classified as polar and non-polar. A non-polar compound occurs when there is an equal sharing of electrons between two different atoms. Examples of household non-polar compounds include fats, oil and petrol/gasoline.Therefore (per the oil and water rule of thumb), most non-polar molecules are water insoluble (hydrophobic) at room temperature.hen comparing a polar and non-polar molecule with similar molar masses, the polar molecule generally has a higher boiling point, because of the dipole-dipole interaction between their molecules. The most common form of such an interaction is the hydrogen bond, which is also known as the H-bond.
The Outer Ear. Parts of the Ear: Outer Ear | Middle Ear | Inner Ear. The outer ear consists of the pinna, or auricle, and the ear canal (external auditory meatus). The pinna â the part of the ear that we see on each side of our heads â is made of cartilage and soft tissue so that it keeps a particular shape but is also flexible. The pinna serves as a collector of sound vibrations around us and guides the vibrations into the ear canal.
Vestibule contains. The utricle and saccule in the inner ear, contain maculae (specialized epithelium) made of hair cells (sensory neurons), hairs are embedded in an otolithic membrane, otolithic membrane consists of a gelatinous mass and crystals called otoliths, otolithic membrane move in response to gravity.
