Why do scientists study fossils?
Tasya [4]
Hi,

By studying fossils, scientists can learn how life has changed over time, how earth's surface has changed and what past environments were like. Fossils form when living things die and are buried by sediment; they are usually found in Sedimentary rock. Only the hard parts of organisms generally leave fossils because the soft parts generally decay too quickly to fossilize. In case you didn't know, there are two types of fossils; rock fossils and preserved fossils.

Option c) is the correct option above.

<span>c) Fossils give information about the time period in which organisms lived in the past.

Answer: What is the defining characteristic of eukaryotic cells? Put these in your own words.

Eukaryotic cells are defined by the presence of a nucleus containing the DNA genome and bound by a nuclear membrane (or nuclear envelope) composed of two lipid bilayers that regulate transport of materials into and out of the nucleus through nuclear pores.

There is a wide range of eukaryotic organisms, including all animals, plants, fungi, and protists, as well as most algae. Eukaryotes may be either single-celled or multicellular.
