Interferons help other cells resist the infection of viruses. They prevent the synthesis of a virus's proteins in infected cells and help block the virus from reproducing (replicating itself). This slows down the process of the infection <span>and gives the immune system time to respond to the virus.</span>

Answer: D) A car with the windows rolled up gets very hot on a summer day.
A radiation can be defined as the transmission of energy in the form of waves, particles or rays through space or through a material medium. A radiation is being transmitted from one source till it reaches it's destination. A radiation transfers heat energy. A car with the windows rolled up gets very hot on a summer day would be evidence that heat was transferred by radiation because the glass pane of the window of the car being transparent will absorb the heat energy coming from the solar radiation.
Answer:
Option A, option B. Option A and B are specific to retroviruses, although option c and d are also true, they are not specific only to retroviruses.
Explanation:
Retrovirus is a type of virus that uses RNA as its genetic material. After infecting a cell, a retrovirus uses an enzyme called reverse transcriptase to convert its RNA into DNA. The retrovirus then integrates its viral DNA into the DNA of the host cell, which allows the retrovirus to replicate.
