1. viruses have genome configurations that are either plus-sense or minus-sense
2. viruses have processes of replication, transcription, and translation that are the most similar to those used by cells.
3. and viruses replicate using DNA polymerases, either their own or from those of the host.
4. viruses contain an RNA-dependent DNA polymerase called reverse transcriptase that is used generate a DNA intermediate
5. viruses have replication that involves first generating a complementary DNA strand.
6. and viruses carry their own nucleic acid polymerases (called replicases) to replicate the viral genome with no DNA intermediate
7. is the genetic material of virophages

1. Single stranded RNA viruses have genome configurations that are either plus-sense or minus-sense.

2. Double stranded DNA viruses have processes of replication, transcription, and translation that are the most similar to those used by cells.

3. Single stranded and double stranded DNA viruses replicate using DNA polymerases, either their own or from those of the host.

4. Retro viruses contain an RNA-dependent DNA polymerase called reverse transcriptase that is used generate a DNA intermediate.

5. Single stranded DNA viruses have replication that involves first generating a complementary DNA strand.

6. Single stranded and double stranded RNA viruses carry their own nucleic acid polymerases (called replicases) to replicate the viral genome with no DNA intermediate.

7. Double stranded DNA is the genetic material of virophages.

Explanation:

Viruses are seen as small obligate intracellular parasites, which contain either a RNA or DNA genome surrounded by a protective, virus-coded protein coat. They may be viewed as mobile genetic elements, classified based on their morphology or mode of replication (that is, single stranded and double stranded DNA and RNA viruses).

A viral genome replication where the template is single-stranded RNA, and which proceeds via a double stranded DNA, intermediate molecule. Viral genomic RNA is first reverse transcribed into dsDNA, which integrates into the host chromosomal DNA, where it is transcribed by host RNA polymerase II.

A retrovirus is a type of RNA (not DNA) virus that inserts a copy of its genome into the DNA of a host cell that it invades, thus changing the genome of that cell.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
