Not sure if all of it is correct but hope at least some is
Viruses are the microorganisms who needs to infect the living host cells, in order to replicate or reproduce. These infectious agents are capable of injecting and infecting all the life forms present, including the plants, animals and bacteria. The viruses were not among the first organisms to evolve as in order to replicate themselves and continue through the time they needed other organisms' cell.
Hence, the correct answer is 'viruses have to infect a living cell in order to reproduce'.
The flow of genetic information<span> follows the "Central Dogma" of molecular biology: DNA is copied as messenger RNA (mRNA) which in turn is the template for protein synthesis (uses rRNA and tRNA). </span>Genes<span> (DNA) specify the amino acid or nucleotide sequences of functional cellular proteins and RNAs.</span>
When winds move air masses, they carry their weather conditions (heat or cold, dry or moist) from the source region to a new region. When the air mass reaches a new region, it might clash with another air mass that has a different temperature and humidity. This can create a severe storm.
so therefore the answer is a,b,and c
