Question

Which of the following best describes a model in science?

A. A set of ideas about what something is and how it functions
B. A small version of a physical structure built to represent a larger real structure
C. A person who promotes science to the public
D. A set of observations about how something behaves or functions.

Answer 1

A model in science is a simplified representation of something that is difficult or impossible to observe directly. It helps us understand complex systems and make predictions.

Step-by-step explanation:

A model in science is a representation of something that is often too difficult or impossible to observe directly. It is a simplified version of the real world that helps us understand complex systems and make predictions. For example, the planetary model of the atom is a model that visualizes how electrons orbit the nucleus, even though we cannot directly observe electron orbits.
