  1. 3. A relationship that measures the strength of interdependence of 2 variables.
  2. 4. A contagious viral illness caused by the varicella virus, characterised by an itchy rash.
  3. 5. To introduce a substance or microorganism into another organism.
  4. 6. A period of isolation that separates or restricts the movement of people to control the spread of infectious disease.
  5. 8. This evaluates the appropriateness of the information for the topic under investigation.
  6. 15. Any organism or agent that causes or can cause disease or illness to its host. Pathogens can include bacteria, viruses, fungi, protozoa and parasites.
  7. 16. A substance that kills microorganisms or stops them from growing and causing disease.
  8. 18. An illness caused by organisms that can be passed, directly or indirectly, from one living thing to another. Examples include malaria, COVID-19, influenza, cholera and herpes.
  9. 19. The connection between the independent and dependent variable.
  10. 20. A disease that persists in a community at a consistent level over time.
  11. 21. Occurs when the fitted model, such as a line of best fit is used to make predictions using values that are outside the range of the original data upon which the fitted model was based (NESA 2023).
  12. 22. An epidemic that has spread over several countries or continents and affects a very large number of people.
  13. 23. A living thing that can only be seen through a microscope. For example, bacteria and fungi.
  14. 24. The act of introducing a vaccine into the body to produce protection from a specific disease.
  15. 25. The process whereby a person is made resistant to a disease, typically by administering a vaccine.
  16. 28. The number of newly diagnosed cases of a disease.
  17. 29. Making predictions between known data values. For example, working between 2 known points on a graph to predict a value in between these points (NESA 2023).
  18. 30. The spread or transfer of a pathogen causing infectious disease from an infected individual to a non-infected individual.
  19. 31. The body system that prevents and fights disease.
Down
  1. 1. Where a disease is passed directly from one infected person or animal to another person or animal. Examples include kissing, touching, sexual contact, and air-borne droplets spread through coughing, sneezing and talking.
  2. 2. Produced by the body’s immune system. They attach to pathogens and destroy them.
  3. 7. An illness or condition of the body affecting how an organism, or parts of an organism, or its organ’s function. For example, COVID-19, diabetes and malaria (NESA 2023).
  4. 9. The general direction of the graph (typically only derived from line graphs or scatter plots with a line of best fit).
  5. 10. A temporary occurrence of a disease that spreads rapidly and extensively within a specific population, community, or region, typically affecting a significantly higher number of individuals than expected (NESA 2023).
  6. 11. A preparation that stimulates the body's immune response against a specific infectious agent or disease.
  7. 12. This refers to the consistency of information with other reliable sources.
  8. 13. When data repeats predictably.
  9. 14. When a disease is passed from an infected person to another person, even though they have not had direct contact. For example, airborne transmission, food, water and surfaces.
  10. 17. Requires another organism to transmit the disease from person to person. Mosquitoes are vectors for malaria, dengue fever, Ross River fever and Japanese encephalitis.
  11. 26. An infectious agent (pathogen) that only replicates within a host organism, causing illness.
  12. 27. The information presented is correct, with information we know to be true.
