Question

an animal dies in mud, decomposes, and leaves an imprint, which is later filled by sediment to form a solid copy of the original organism. how is this fossil different from fossils of preserved remains? only hard tissue is preserved. hard and soft tissues are preserved. only soft tissue is preserved. there is little change to the preserved organism.

Explanation:

Preserved remains fossils have little change to the original organism (like in amber or tar pits). The described fossil (imprint filled with sediment) is different. In preserved remains, the actual organism parts are kept with minimal alteration. Here, it's a cast (imprint filled) rather than the original organism with little change.

Answer:

There is little change to the preserved organism.
