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.

Answer:
Here is the complete statement: Cells are starved of energy when GLUCOSE is unable to enter.
Explanation:
Glucose, which is a monosacharide is the primary source of energy for all the cells in the body of humans. Glucose is the end product that is typically obtained from the digestion of carbohydrate. After digestion, the glucose is absorbed by the small intestine and is transported into the blood. Glucose needs the enzyme insulin in order to enter the body cells. When the glucose enter the cells, the cells use it to produce energy in the form of ATP. Without energy cells can not survive.
Without the help of insulin, glucose will not be able to enter the cells and the cells will starve and start to look for other meaning of biological fuel. This may include breaking down the protein in the body to convert it to glucose for energy.
The disease condition in which glucose that is present in the blood is not able to enter the cells due to non functional insulin is called diabetes mellitus.
