  1. 2. Disease caused by bacterium vibrio cholerae. Symptoms include severe diarrhoea, weakness, muscle pain, low blood pressure and rapid heart rate.
  2. 5. Treatment for diarrhoea involving feeding a patient a solution of glucose and salts in sterile water.
  3. 7. In animal cells such as sperm. A tail-like structure that beats from side-to-side, producing movement, in some bacteria; a structure with a similar function but much smaller and with quite a different structure.
  4. 11. Animal without a vertebral column (backbone)
  5. 12. Factor in a process of reaction that limits (holds back) the process, e.g. a nutrient that is in short supply.
  6. 14. Immunity gained as a result of antibodies supplied to the body from somewhere else, e.g. to a fetus across the placenta, to a baby in its mother’s milk or by injection.
  7. 15. Disease caused by the protozoan parasite Plasmodium, passed to humans by mosquitoes.
  8. 16. A type of reproduction, where an organism reproduces by dividing n two. Exact copies of the parent cell are produced.
  9. 17. Organisms that gain their energy by feeding on dead or decaying material.
Down
  1. 1. Disease caused by the bacterium Salmonella typhi. Symptoms include fever, headaches, cough, stomach cramps and diarrhoea. Toxins from the bacteria can cause multiple organ failure.
  2. 3. Slime layer covering some bacterial cells. Protects the bacterium and stops it drying out.
  3. 4. Pathogenic bacterium that is resistant to many antibiotics, in hospitals, MRSA is responsible for many difficult-to-treat infections
  4. 6. Skin disease caused by a fungus. Symptoms include sore red patches on the skin between the toes.
  5. 8. Immunity gained by vaccination of by infection of antibodies.
  6. 9. Protein produced by lymphocytes that binds with foreign antigens as part of the immune response.
  7. 10. Immunity developed naturally, either in response to an infection, through antibodies received by a baby in its mother’s milk, or by a fetus across the placenta.
  8. 13. Type of composting toilet where the user squats over a trench or pit. Relies on microorganisms in the pit to break down urine and faeces.
