Question

question 4. an engineer made a 3d model of a heart to help him think about how it functions. he made sure that some characteristics of the heart were accurately represented, but he did not include all the hearts characteristics in his model. is it acceptable that he ignored some of the hearts characteristics in his model? a. no, because he ignored some of the hearts characteristics, and a model should be like the object represents in every way possible. b. yes, but only if he represented the characteristics that affected whether the model looks like the heart, because models should look like the things that they represent. c. yes, but only if he represented the characteristics that people would be interested in knowing about, because models are only used to communicate information to others. d. yes, but only if he represented the characteristics that affect how the heart functions, because models need to include the characteristics that are relevant to what is being studied.

Explanation:

Models are simplified representations used to communicate information. They don't need to capture every characteristic of the object. As long as the important characteristics related to the study (in this case, how the heart functions) are represented, it can be acceptable.

Answer:

D. Yes, but only if he represented the characteristics that affect how the heart functions, because models need to include the characteristics that are relevant to what is being studied.
