Name at least two limitations of using models in science.

Explanation:

Missing Details. Most models can't incorporate all the details of complex natural phenomena. 

Most Are Approximations. Most models include some approximations as a convenient way to describe something

Models may be oversimplified, leading to misunderstanding about the subject. Sometimes models cannot represent all aspects of an object or system. Finally, models are only as accurate as current scientific knowledge.

Explanation:

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )
