Answer:
"Viral reverse transcriptase to make a DNA copy that is integrated into the host genome and then host RNA polymerase transcribes it is a true statement.
Explanation:
The virus is an infectious agent which is not considered living either considered non- living. The virus particles contain the genetic material that determines the trait of a virus in the form of either DNA or RNA.
The virus which contains the RNA replicates themselves by fist converting their RNA into DNA by reverse transcriptase enzyme. Once the DNA is made, the DNA is incorporated in the genome of the host and the machinery of the host performs the replication, transcription and translation.
Thus, the selected option is true.

If the us modifies techniques for timber management, it is expected that us forests will be able to meet long term timber needs
<h3>If the US modifies techniques for timber management?</h3>
Forest management is the rational and environmentally appropriate use of forest resources. Management is an economic activity opposed to deforestation, as there is no total removal of the forest and even after use, the site will maintain its forest structure.
With this information, we can conclude that If the us modifies techniques for timber management, it is expected that us forests will be able to meet long term timber needs.
