<em>Answer:</em>
<em>Limestone is a type of carbonate sedimentary rock. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate. A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO₃)₂.</em>
<em>Limestone has numerous uses: as a building material, an essential component of concrete (Portland cement), as aggregate for the base of roads, as white pigment or filler in products such as toothpaste or paints, as a chemical feed stock for the production of lime, as a soil conditioner, and as a popular decorative .</em>
<em>Limestone is formed in two ways. It can be formed with the help of living organisms and by evaporation. Ocean-dwelling organisms such as oysters, clams, mussels and coral use calcium carbonate (CaCO3) found in seawater to create their shells and bones.</em>
<em>LIMESTONE MEANING:</em>
<em>a rock that is formed chiefly by accumulation of organic remains (such as shells or coral), consists mainly of calcium carbonate, is extensively used in building, and yields lime when burned.</em>

Answer:
Explanation:
Cochlea: Hair cells are the ones that are responsible for transduction from sound vibration to electrical energy and they are located in the inner ear. Vibrations of sound are the ones that cause vibrations in air molecules and they shake up the ear drum. As the eardrum is moving, it's causing bones that are located in the middle ear to vibrate, too. They are further passed to the cochlea.
Retina: is the part of visual system and it contains sensory cells named rod, and the cone cells. In retina, they have a role of converting physical energy in shape of light signals into electrical impulses, which later travel to the brain. Then the adaptable change occurs and it forms a motion of series of molecules which give, as a result, reduction of the photoreceptor.
