Question

fossils quiz complete 1 2 3 4 5 6 7 8 9 10 study the image. how does this fossil differ from fossils that have preserved remains? which feature does this fossil have that preserved remains do not have? ∘ it has carbon residue left by a decaying organism. ∘ it was formed by tree sap that turned into amber. ∘ it was preserved in frozen soil called permafrost. ∘ it includes the preserved soft tissue of an organism.

Explanation:

To solve this, we analyze each option:

• Option 1: The fossil in the image appears to be a mold or cast (impression of the organism), and carbon residue from decaying organisms is part of carbonization, which can leave a residue (like a thin film of carbon) that's different from preserved remains (which might have hard parts or sometimes soft tissue but not just carbon residue in the same way). Preserved remains (like in amber or permafrost) have more intact parts, while this fossil (a plant impression) likely has carbon residue from the decaying plant.
• Option 2: Tree sap turning to amber preserves organisms trapped in it, but the image doesn't show amber - it's a rock - based fossil.
• Option 3: Permafrost preservation is for organisms frozen in ice, not a rock - based fossil like the one shown.
• Option 4: Preserved remains with soft tissue are rare (like in amber or permafrost), but the fossil here is an impression, not soft tissue preservation.

So the correct option is the one about carbon residue.

Answer:

A. It has carbon residue left by a decaying organism.
