The best answer from the options provided is: A dissected pig's inner structure is slightly different than a human's.
Here's a brief analysis of why this answer is appropriate:
-
Dissected Pig vs. 2D Model: A dissected pig can provide a real, physical representation of biological structures, allowing for hands-on learning experiences. However, the anatomy of pigs is not identical to that of humans, as there are notable differences in the arrangement and structure of organs.

Other Options:
- "A dissected pig's inner structure is completely different than a human's" is too extreme; while there are differences, many aspects of mammalian anatomy are similar.
- "A dissected pig does not reveal the arrangement of organs" is incorrect because a dissection usually shows the arrangement, just not the same as in humans.
- "A dissected pig is less detailed than a 2D model" is misleading; while a 2D model can illustrate complex arrangements clearly, it lacks the three-dimensional context provided by a dissection.
Overall, the slight differences in structure and arrangement between pigs and humans are a significant factor in understanding the limitations of using a dissected pig as a model for studying human anatomy.
