The answer is D.
A retrovirus is any of a group of viruses that characteristically carry their genetic information in form of RNA. These viruses have an enzyme called reverse transcriptase from which they derive their name because they follow the first step of the central dogma backward thus "retro" which means backward.
Reverse transcriptase makes DNA from RNA template thus reversing the usual pattern of transcribing RNA using DNA as the template.
The central dogma of molecular genetics summarizes steps of protein synthesis as DNA → RNA → protein. But retroviruses have modified the process to be RNA → DNA → RNA → protein.

Renewable energy processes present us with alternative sources of energy.The alternative energy sources applied to the energy sources other than remains in the form of fossil fuels. These energy sources are existing in the structure of solar power, tidal energy, geothermal power, electricity obtained from wind energy, and biomass.
The most numerous cells in the lungs are dust cells, also known by their scientific term of alveolar marcrophages.
These cells are located in any person's lungs and are responsible for keeping your lungs and air pipes clean of any dust particles and other materials that may harm your body. Their role is to destroy any foreign substances, such as bacteria and others.
