Answer:
One pair of chromosomes includes a gene called the cystic fibrosis transmembrane conductance regulator (CFTR) gene. This gene is large and complex — in fact, more than 1,000 different CF-related mutations have been identified.
In most people, the CFTR gene helps regulate the flow of salt and fluid in and out of cells. But if there is a mutation in this gene, chloride, a component of salt, gets stuck inside the cells and a thick, sticky mucus starts to build up inside the body.

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.
