Classification systems are mental models that we create to make sorting things simpler and more efficient. We make compromises to emphasize certain details and hide others based on their perceived relevance to achieving the outcomes we seek. Even if the original model was nearly perfect, you should expect the inputs provided and outcomes desired to change as time goes by.
In time, we usually find that we have over-simplified by ignoring important details. Mental models such as classification systems should evolve over time. This enables them to more accurately reflect reality and lead to the outcomes we seek.
You can only find the details you seek by observing the right layer of abstraction.
An organism is the level of organization in living things
The steps would be :
1. Rapid and reversible formation of local secondary structure
2. Formation of domain through cooperative aggregation of folding nuclei
3. molten globule formation of assembled domains
4. adjustment in conformation of domain.
5. Final protein monomer formation
The answer is C. Atoms. Atoms make up everything.
