Questions:
- Question 1: Focuses on Salmonella bacteria, including causes of symptoms of infection, prevention methods and treatment with specific drug types. It also involves understanding why recovery might take longer in individuals with AIDS.
- Question 2: Examines metabolic processes, including specific examples like lipid formation, involving calculation of percentage decrease in a metabolic rate.
- Question 3: Includes a scenario about the effectiveness of different cleaning liquids. Results are presented in graphs, requiring determination of the effectiveness of cleaning liquids (liquid A, B) and comparisons.
- Question 4: Involves how Salmonella bacteria are transmitted and prevention strategies by chickens being vaccinated..
- Question 5: Discusses bacterial infections, identifying specific pathogens and their mechanisms of entry into plants.
- Question 6: Involves designing an experiment about heart rates in smokers and non-smokers, during exercise. The aim is to identify any noticeable differences.
- Question 7: Covers the composition of the circulatory system, focusing on the transport of substances in the blood plasma. Includes an explanation of why more red blood cells are advantageous for athletes. The content also includes blood vessel analysis, specifying those transporting deoxygenated blood.
- Question 8: Detailed investigation of a circulatory system with particular reference to blood vessel types and structure, and heart pacemaker locations.
- Question 9: Contains a scenario detailing a methods used by a scientist on an investigation about the effects of cleaning materials on the growth of Salmonella bacteria, requiring measurement of an area where bacteria are not growing.
- Question 10: Focuses on the design and methodology of an experiment on the effects of exercise on the heart rate of smokers versus non-smokers, demonstrating a clear understanding of investigative methods and experimental design.
- Question 11: Involves calculation of the time it takes for particular heart rates to return to the original, resting heart rate.
- Question 12: Contains an examination of the effect of chicken eggs being put in an acid. It involves calculating percentage change in mass, and explaining why the mass of the eggs increased, providing rationale for results.
- Question 13: Contains a detailed investigation on the effects of some materials on some bacterial components of milk, requiring a determination of the factors contributing to the differences in the outcome of two test samples.
