Which definition best describes a scientific model? a thinking aid based on submicroscopic observations a thinking aid based on many scientific hypotheses a thinking aid based on macroscopic observations a thinking aid based on evidence that has not yet been widely accepted but needs approval?

A thinking aid based on many scientific hypotheses

Explanation:

Submicroscopic and macroscopic observations are characteristic of scientific models of physics and chemistry, but scientific models are not exclusive to that two sciences, because there are also other scientific models such as mathematics, graphics and conceptual.

A scientific model must be sufficiently evidence-based, so it has already obtained approval.

Therefore a scientific model can be defined as a thinking aid based on many scientific hypotheses. To make a model it is necessary to raise certain hypotheses so that the representation of the result we want to obtain is as accurate as possible.
