How to approach this question
After burial, decomposition still occurs, but it is slowed down. Which parts of an organism, like skin and muscle, are most likely to rot away?
Full Answer
G.soft parts✓ Correct
soft parts
Even when an organism is buried, microorganisms will break down its tissues. The soft parts, such as skin, muscles, and internal organs, decay relatively quickly. The hard parts, like bones, shells, or the exoskeleton of a trilobite, are much more resistant to decay and are the parts that are most likely to be preserved as fossils.
Common mistakes
✗ Choosing "hard parts" or "bones". These are the parts that are preserved, not the parts that decay.
