Which of the following is not a benefit to using scientific models?
a. scientific models scientists gain a better understanding of concepts and events.
b. scientific models aid in communication about concepts and events.
c. scientific models are never subject to change.
d. scientific models can answer scientific questions.

Correct C). Scientific models are never subject to change.

The scientific model is a representation of a specific phenomenon, which make it easy to understand. It may be a picture, diagram, computer program or a set of complex mathematics that easily describe the problem. The main aim is to make a particular thing that you easy to understand. It predicts what will happen in the future. It is used to gain a better understanding of any process or system.

Hence, the option C is not a benefit of using a scientific model.

c. Scientific models are never subject to change.

Scientific models serves as simulations to whatever is happening in a bigger basis. Above choices are its benefits except letter C because, as it is only a simulation, it could also be subjected to change to fit the bigger and actual event.
