Question

practice it!
select the statement(s) that are true about the limitations of scientific models.
a model is a best guess or approximation.
a model does not allow scientists to compare size, distances, and movements of objects or systems.
a model cannot replace reality.
a model is an exact replica of the object or system that it is representing.
a model is only as good as the information provided to build it.

Explanation:

• For "A model is a 'best guess' or approximation": Scientific models are simplified representations, so they are approximations of real - world systems. This statement is true.
• For "A model does not allow scientists to compare size, distances, and movements of objects or systems": Models actually help scientists in comparing these aspects (e.g., scale models of the solar system help compare distances between planets). So this statement is false.
• For "A model cannot replace reality": Models are representations and can never fully capture all aspects of the real - world system, so they can't replace reality. This statement is true.
• For "A model is an exact replica of the object or system that it is representing": Models are simplified and not exact replicas (e.g., a model of an atom is not an exact replica of a real atom). So this statement is false.
• For "A model is only as good as the information provided to build it": If the input information for building a model is inaccurate or incomplete, the model will also be flawed. So this statement is true.

Answer:

A. A model is a 'best guess' or approximation.
C. A model cannot replace reality.
E. A model is only as good as the information provided to build it.
