What is a risk factor for developing cardiovascular disease?
High blood pressure, smoking, lack of exercise, or a diet high in saturated fats.
How do white blood cells defend the body against pathogens?
White blood cells engulf pathogens (phagocytosis), produce antibodies to fight infections, and release antitoxins to neutralise toxins.
What is the difference between a bacterial infection and a viral infection?
Bacterial infections are caused by bacteria and can often be treated with antibiotics, whereas viral infections are caused by viruses and usually require vaccines or antiviral drugs.
Why do antibiotics not work on viruses?
Viruses reproduce inside host cells, so antibiotics cannot target them without damaging the body’s own cells.
What are monoclonal antibodies and how are they used in medicine?
Monoclonal antibodies are artificially produced antibodies that target specific cells, used in treatments like cancer therapy and pregnancy tests.
Describe two ways in which new drugs are tested before they are approved for use.
Preclinical testing: Tested on cells, tissues, and animals to assess safety and effectiveness.
Clinical trials: Tested on healthy volunteers and patients to check for side effects and effectiveness.
How can plant diseases be detected?
By observing symptoms (e.g., discoloured leaves, lesions), using testing kits, or analysing DNA for specific pathogens.
What is herd immunity and how does it help prevent disease outbreaks?
Herd immunity occurs when a large percentage of the population is vaccinated, reducing the spread of a disease and protecting those who cannot be vaccinated.
Why is it important to complete a full course of antibiotics?
To ensure all bacteria are killed and prevent antibiotic resistance from developing.
How do plants defend themselves against pathogens?
Physical barriers (e.g., waxy cuticles, cell walls) and chemical defences (e.g., antimicrobial chemicals, poisons to deter herbivores).
