Scientists rely on models to represent concepts and processes in physical science. which one of the following is a reason why scientists use models? a. models are always colorful b. models only show large objects. c. models might be hazardous (not safe). d. models can represent things that are too small to see.

Option (D)

Explanation:

Scientists use models in order to explain the composite data as well as presenting hypothesis. These models are very important because it helps in visualizing the things that are not actually visible to our naked eye. For example, the earth-moon system can be described by using a model that includes a tennis ball and a foot ball. This enables us to understand the concept of any particular system and by analyzing its parameters and making proper observation, the final conclusions are made. All naturally occurring science is entirely based on models.

Thus, the correct answer is option (D).
