If crossing over does not happen the product is parental gametes. Meaning there is less genetic variation.
B only in the nucleus and rough ER
The answer is C, because if something contagious we’re to threaten the population of the species then not having any variant means they’re all the same and it would kill them all and cause them to go extinct

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.
