Question

1. why are scientific models important? they help scientists explain concepts that are difficult to observe. they help scientists prove scientific theories. they help scientists prove scientific laws. they help scientists explain complex questions

Explanation:

Scientific models simplify complex or unobservable phenomena (e.g., atomic structure). They are tools for explanation, not for proving theories (which require extensive evidence) or laws (which are well - established descriptions). While they can address complex ideas, their key role is in explaining hard - to - observe concepts.

Answer:

They help scientists explain concepts that are difficult to observe.
