Science Chapter 11A Section Review

Suggest a situation that formed a fossil and preserved its DNA or soft tissue?

A situation formed a fossil and preserved its DNA is an Amber trap. Ice traps also can have preserve of soft tissue in Canada and Siberia.

Why do the La Brea Tar Pit fossils represent a local community of plants and animals that lived in Southern California during the Ice Age?

Why do the La Brea Tar pit represent a local community of plants and animal is because most of the animals and plants found their are not extinct. When large animals died the attracted scanvengers. Also because of climate during the glacier age near Los Angles.

Why would evolutionists have problems explaining the existence of soft tissues in a mineralized fossil?

Why evolutionists have problems explaining the existence of soft tissue in mineralized fossils is because soft tissues can last longer than ever imagined.

Is a chicken bone found in a waste dump a fossil? Explain your answer?

No a chicken bone in a waste dump is not a fossil because it is not preserved and protected.

(True or False) A trace fossil is an impression of an organism that remains after the original material decays or dissolves away.

False: impressions of organisms not remains

What fossil evidence supports rapid and recent burial?

The evidence that supports rapid and recent burial is detailed casts of soft tissues and even of hair and feathery coverings in the sediments.

Which kind of fossilization process leaves behind a three-dimensional shape of an organism made out of minerals?

The kind of of fossilization process that leave behind a three-dimensional shape is Cast and Molds and Petrified fossils.

What happens to the remains of nearly all living things that die? What normally does not happen to these organisms?

What happens to the remains of nearly all living things is that they either decompose or get eaten by scavengers. What normally does not happen to these organisms is fossilized and preservation. Decay can't happen as fast because of bacteria and fungi can't live or grow as well.

Where can we find fossils?

We can find fossils in sedimentary rocks. The best preserved fossils are nearly found in fine-grained rocks.
