Question

which of the following statement best describes a physical/scientific model? a a 3d model of dnas double helix structure b a drawing showing the structure of an atom c a formula explaining the behavior of gases d an equation predicting how planets move around the sun

Explanation:

A physical scientific model is a tangible or visual - representation of an object, system, or concept in science. Options C and D are formulas and equations which are mathematical models. Option A is a 3D model of DNA's double - helix structure and Option B is a drawing of an atom's structure. Both are physical models, but a drawing is a two - dimensional representation while a 3D model is more physical in nature.

Answer:

A. a 3D model of DNA's double helix structure
