Answer: Option C
Explanation:
The basilar membrane can be defined as membrane which is stiff in nature and is found in the cochlea of the inner ear that separates two fluid filled tubes which runs along the coil of the cochlea, scala tympani and scala media.
The movement of the basilar membrane causes the movement of the streocilia as it is attached to the basilar membrane.
The tectorial membrane along with the hair cells move with the streocilia bending with the relative motion of the tectoria membrane. This helps in signal transmission.
This movement causes opening and closing of the gated channels present on the cilia of the hair cells.
DEET, a popular synthetic insect repellant.
DEET- Numerous repellent products include the active component DEET (N,N-diethyl-meta-toluamide). It is frequently used to ward off biting insects like ticks and mosquitoes. DEET can be applied to kids of any age, according to the FDA. Since results from studies conducted for product registration reveal no difference in effects between young animals and older animals, there is no restriction on the proportion of DEET in the product for use on children.
Insect Repellant- Products that discourage insects are known as insect repellents. These might be skin care products or items like candles or lanterns with heating mechanisms that release repellents.
