  1. 5. When bacteria are able to come together to exchange genes with eachother.
  2. 7. Cycle of virus reproduction where the viral DNA is incorporated into the host cell’s DNA, and may be activated to reproduce viruses at a later time
  3. 10. This person developed the first vaccine (using cowpox to immunize against smallpox)
  4. 11. Substance that helps a person become immune to a disease by stimulating the immune system to protect against future infection.
  5. 18. These get their energy and nutrients by consuming others.
  6. 19. These get energy from inorganic chemicals
  7. 22. Illness caused by infectious agents such as bacteria, virus, or fungi
  8. 23. Cycle of virus reproduction where viruses are assembled immediately after infection of the host cell
  9. 24. Chemical that kills bacteria used to treat bacterial infections
  10. 26. Sphere shaped bacteria
  11. 29. Proteins that help to recognize and fight off disease if you contact it after having been sick or receiving a vaccine.

  5. 6. Bacterial cell division, a form of asexual reproduction
  6. 8. Disproven idea that life can come from nonliving things.
  7. 9. This person showed that food spoiled because of contamination by invisible bacteria, not because of spontaneous generation.
  8. 11. An infectious agent made of DNA/RNA & protein that infects a host cell to replicate
