"viral reverse transcriptase to make a DNA copy that is integrated into the host genome and then host RNA polymerase transcribes it. B. host DNA polymerase to replicate their genome and host RNA polymerase to transcribe it. C. viral RNA-dependent RNA polymerase to replicate their genomes and transcribe it. D. use restriction enzymes to replicate and transcribe their genomes."

"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.

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
