I'm pretty sure that it's natural gas.
Answer:
Transgenic organism are the genetically modified organisms on their molecular level by altering their gene to improve the particular quality that is related to the particular gene in the organisms. It can be perform in bacteria, plants and animals, the produced organisms called transgenic organisms. The beneficial applications of such organism are given as follows:
Transgenic bacteria: these bacteria are first organisms to be genetically modified and used for several functions such as human proteins, producing material plastics and many more.
Transgenic plants: such genetically modified plants can be used to enhance food quality and quantity, to make pest resistant breed and increase the extreme condition tolerance and many more.
Transgenic animals: they are used to improve the quality of food supply, improve medicines and research purposes and many more applications.

Answer:
Radiometric dating methods
Explanation:
Absolute dating is the process of determining an age on a chronological or specified time scale in which events occurred in archaeology and geology. Absolute dating can be determined by using properties of the atoms that make up materials.
The most common method of absolute dating uses by geologists is radiometric dating methods which is based on the natural radioactive decay of certain elements such as potassium and carbon found in the rocks. By comparing the ratio of parent isotope with a known half-life to daughter product in the rock, the age of the rock can be determined.
The carbon-14 isotope is used in radiocarbon dating, but is only useful for measuring recently formed rocks in the geologic past. The decay of Potassium-40 isotope known as potassium-argon (K-Ar) method allows dating of materials that up to 1,000 billion years old.
