Answer: Tympanic membrane.
Explanation:
Sound is a type of mechanical energy, the result of the transmission of energy from vibrating air particles from a sound source to more distant parts. Sound frequency is a concept that characterizes the pitch of a sound, defining it as low, medium or high. The tympanic membrane separates the outer ear from the middle ear. The main function of the outer ear is the protection of the eardrum membrane maintain a certain temperature and humidity balance necessary to preserve the elasticity of the membrane. Contributing to these functions are ceruminous cerumen-producing glands, hair, and epithelial migration from internal to external. The ossicles (hammer, anvil, and stirrup) form a bridge conducting the eardrum vibrations to the inner ear. At waves arrive in the form of amplified mechanical energy. The middle ear consists of the eardrum and three ossicles: hammer, anvil, and stirrup. It transfers through the ossicles the vibratory movement of the eardrum to the oval window of the cochlea.

Kangchenjunga.
Explanation:
In 1847 "Kangchenjunga" or "Kanchenjunga" (8,586 m) was discovered as highest mountain before discovery of mount Everest. It was considered to be the highest mountain from 1838 until 1852.
Answer:
In the presence of oxygen, pyruvate is transformed into an acetyl group attached to a carrier molecule of coenzyme A. The resulting acetyl CoA can enter several pathways, but most often, the acetyl group is delivered to the citric acid cycle for further catabolism.
