What are the three advantages of using conceptual models?

The conceptual model provides a concept of how the components of an atom are arranged, implying a similarity of the forces acting between those components.

It is important to note that the conceptual model is not necessarily correct or accurate. It simply provides a model which forms the basis for the discussion of the concepts involved.

Science is all about the discussion -- with the expressed aim of improving the conceptual model to the point that it is self-consistent and consistent with the existing body of accepted knowledge. [The hardest part is knowing when and how to question the body of accepted knowledge.] 

The main role of dna in the  cell is the long-term storage of information. it is often compared to a blueprint, since it contains the instructions to construct other components of the  cell, such as  proteins  and rna molecules.the main function of rna is to carry information of amino acid sequence from the genes to where  proteins  are assembled on  ribosomes  in the  cytoplasm. mark brainliest, my work is good.
