Answer:

Principle of superimposition states that in undisturbed rock layers, the oldest rocks are on the bottom and the youngest rocks are on the top. Phenomena of withering is behind this process. The rocks are withered due to the effect of water and air. The sediments or soil particles gets accumulated at another location. The layers of sediments gets compact with time and leads to the formation of rocks. The rocks being older are covered by layers of sediments with course of time. These sediments gets compact again forms new rocks. By this way the new young rocks are formed over the older rocks.

Bas_tet [7]

Answer: The chemical reaction in this example is Called hydrolysis in the presence of Lactase

Here is a word equation for the hydrolysis of lactose:

lactose + water → galactose + glucose

Explanation: The equation is called <hydro> + <lysis) of these terms refer to water and splitting respectively. So hydrolysis means splitting with water. Enzymes pull out a monomer by examining where the monomers are connected, and placing a water molecule in between them, resulting in the breakage of the bond between the monomers. Here are two picture to represent it.
