Sure! Here's a breakdown of each option:
A. Fossil record
- This statement is true. Viruses do not have a fossil record because they are not living organisms in the traditional sense. They are considered particles rather than organisms with a fossil record.
B. Traces in history
- This statement is true. While viruses have been present throughout history and have had significant impacts on human health and evolution, they do not leave behind physical traces like fossils.
C. Reproductive ability
- This statement is false. Viruses do have reproductive ability, but they cannot reproduce on their own. They need to infect a host cell and use the host's cellular machinery to replicate.
D. Nucleic acid
- This statement is true. Viruses contain nucleic acid, either DNA or RNA, which carries the genetic information needed for their replication and function.
In summary, the correct answer to the question "Viruses do not have:" is option A. Fossil record.
