which of the following statements about models is true A. scientist use models to understand how systems work B. if an inaccurate scale model is used to create a structure the actual structure will likely have problems C. A diagram is one example of a scientific model D. All of these

D. All of these

Explanation:

All the statements are true.

Models are simplified versions of an aspect of reality that scientists use to understand a particular problem. Models only include some variables, while others are left out, or held constant.

If a scale model is incorrect, then the actual structure will likely have the same issues as the scale. This is because the actual structure is built upon the model structure.

Finally, a diagram is one example of a model. A diagram analyzes a particular phenomenon, making certain assumptions.
