Answer 1

A scientific model is a representation of something that is difficult or impossible to directly observe or study. It is useful for studying complex systems or phenomena that cannot be easily analyzed or experimented with.

Step-by-step explanation:

A scientific model is a representation of something that is often too difficult or impossible to directly observe or study. It is useful for studying complex systems or phenomena that humans cannot easily analyze or experiment with. For example, the planetary model of the atom is a scientific model that helps us understand the behavior of atoms and their electrons, even though we cannot directly observe the electron orbits.
