The controversy surrounding the nucleic acids and proteins, regarding which one of them was formed first is the most popular controversy in the biology world today. The nucleic acids stores and the genetic information. The proteins essential for all the life processes are encoded by the genes formed of the nucleic acids (DNA and RNA). But proteins (enzymes) are required for the formation of proteins from the genes. The inter-dependency of the nucleic acids and proteins on each other possesses a dilemma to the question 'which of them arrived first'.
The answer to this dilemma was answered when it was discovered that RNA was capable of not only carrying the genetic information, but also acting as catalyst to the chemical reaction. This finding supported the notion that the RNA evolved first serving the purpose of both the nucleic acids and emzymes.
A model organisms is a species that has been widely studied, usually because it is easy to maintain and breed in a laboratory setting and has particular experimental advantages. model organisms are non-human species that are used in the laboratory to help scientists understand biological processes.

Answer:
Forms of fossils and there arrangement with layer of rock.
Explanation:
- The seashore is a significant place for the depositional work of waves and it's also one of the significant places for the erosion and weathering of rocks.
- The presence of sedimentary rocks along the cliffs are essential for the discovery of fossils of plants and animals. Fossils of shells and other creatures that were of marine origin are mostly discovered near excavation sites. Fossil helps to prove the age of rocks and strata.
The answer is C. hope this helps
