Question

which correctly lists three materials that preserve soft tissues in fossils?
amber, minerals, and sediment
minerals, permafrost, and amber
permafrost, amber, and tar
sediment, minerals, and tar

Explanation:

• Amber: It is fossilized tree resin. When organisms get trapped in it, the resin hardens and can preserve soft - tissue details of small organisms like insects.
• Permafrost: The extremely cold temperatures in permafrost regions slow down decomposition processes. This allows for the preservation of soft tissues in organisms that have been buried in permafrost, such as some ancient mammals.
• Tar: Tar pits can trap organisms. The anaerobic (oxygen - free) environment in tar pits inhibits the growth of decomposing bacteria and other organisms that break down soft tissues.

Answer:

permafrost, amber, and tar
