Question

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

Explanation:

• A model is not an exact replica. It is a simplified representation. So the first statement is false.
• A model is an approximation or 'best guess' based on available data. So the second statement is true.
• The quality of a model depends on the information used to build it. So the third statement is true.
• A model is a representation and cannot replace the real - world object or system. So the fourth statement is true.
• Models can be used to compare size, distances, and movements (e.g., a scale model of the solar system). So the fifth statement is false.

Answer:

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