which of the following phrases best describes the term scientific model?
a. an experiment in which variables are controlled
b. a simplified representation used to explain or make predictions about something
c. the application of scientific knowledge to make predictions about an object, system, or process
d. a physical copy of a scientific object, system, or process

Explanation:

A scientific model is a simplified version of a real - world object, system, or process that helps in explaining or making predictions. Option A describes a controlled experiment, not a model. Option C is more about scientific application rather than a model. Option D is too literal as a model isn't just a physical copy.

Answer:

B. A simplified representation used to explain or make predictions about something
