Question

question 6. an astronomer made a model of the solar system to help him think about how it works. he made sure that some characteristics of the solar system were represented in his model. is it acceptable that he ignored some of the solar systems characteristics in his model? a. yes, but only if he represented the characteristics that affected whether the model looks like the solar system, because models should look like the things they represent. b. yes, but only if he represented the characteristics that affect how the solar system works, because models need to include the characteristics that are relevant to what is being studied. c. no, because he ignored some of the solar systems characteristics, and a model should be like the object it represents in every way possible. d. yes, but only if he represented the characteristics that people would be interested in knowing about, because models are only used to communicate information.

Explanation:

Models in science are simplified representations. They don't need to include every single characteristic of the real - world object or system. They focus on the key features that are relevant to the purpose of the model. In the case of a solar - system model, as long as it represents the characteristics that affect how the solar system works, it can be acceptable even if it ignores some other characteristics.

Answer:

A. Yes, but only if he represented the characteristics that affected whether the model looks like the solar system, because models should look like the things they represent.
