Explanation:
All living organisms' cell are composed of genetic material in form of DNA. The DNA encodes the information needed for the production of useful products (proteins). The way in which the information is encoded is called the GENETIC CODE. It consists of all the triplet nucleotides in DNA or RNA that encodes an amino acid.
This genetic code is universal i.e. the same genetic code is employed by virtually all living organisms, as a codon does not encode another amino acid in another organism. It is universal that AUG specifies Methionine in all living organisms. This shows that all organism share a common evolutionary history.
Hence, it is possible for an organism to express a gene from another organism since the same genetic code will be used to read the information in the gene.
The situation would be that, in a sealed tube, there are 3 to 4 nails inside and a certain amount of calcium chloride was added. After three days, there will be no changes to be observed in the first tube since the oxygen is not enough to initiate a change and there is no presence of water. For the second test, the same situation is made but boiling water was filled in the tube. For this, no changes would still be observed since there is no moisture. For the last test, the same situation as the first but it is filled halfway with water. After 3 days, rust would be observed on the nails. In order for rust to happen, there should be water and oxygen. The oxygen in the early atmosphere of the Earth would react with iron present in the oceans thus producing iron ores.

Answer:
The correct answer is principle of superimposition.
Explanation:
According to the superimposition principle, in the undisturbed rocks, the youngest rocks are situated on the top and the oldest rocks are found in the bottom. The phenomenon takes place due to withering. The rocks get withered because of the influence of air and water.
The soil particles or the sediments get gathered at another site. The deposits of sediments get concentrated with time and result in the production of rocks. The mature rocks get surrounded by the layers of sediments with time passing by. These sediments get concentrated again to produce novel rocks. Through this procedure, the fresh young rocks get produced over the older ones.
