  2. 2. a small petrel of southern seas, having a wide bill fringed with comblike plates for feeding on planktonic crustaceans.
  3. 5. reproduction Viral replication is the formation of biological viruses during the infection process in the target host cells. Viruses must first get into the cell before viral replication can occur.
