Ageing is the process where there is a continuous decline in the metabolism of the body. The hearing power also declines after the age of 40 years. Presbycusis is the term which is generally used for hearing impairment due to old age. It is mainly caused due to degeneration of the cochlea or associated structures of the inner ear or auditory nerves.

Storage sprouting of potato can be prevented by
-
IAA
-

Maleic hydrazide : It is a growth retardant which checks cell division. So during seed storage this is applied for checking sprouting of potato tubers so that the importance of potato may not be lowered down.

None of the above but present below epithelial cells
All epithelia are separated from their underlying tissues by an extracellular basement membrane which is fibrous in nature. The basement membrane is the fusion of two lamina namely, the basal lamina and the reticular lamina. The lamina reticularis is attached to the basal lamina with collagen anchoring fibrils and fibrillin microfibrils. The two layers together are collectively referred to as the basement membrane.
