The 20 questions
-
What biological characteristic allows bacteria to evolve very rapidly?
- lack of mutations
- slow cell division
- fast reproduction rate
- complex nervous systems
-
What is produced by random mutations in bacterial pathogens?
- new tissues
- new organs
- new species
- new strains
-
What does a resistant strain do when an antibiotic is used?
- dies and disappears
- changes into a virus
- survives and reproduces
- becomes dormant forever
-
What type of pathogen is MRSA known to be?
- a protozoan parasite
- a fungal spore
- a harmless virus
- antibiotic resistant bacteria
-
Why do antibiotic-resistant bacterial strains spread so easily through a population?
- effective treatments
- high patient vaccination
- strong patient immunity
- lack of immunity
-
Which practice should doctors avoid to help prevent antibiotic resistance?
- prescribing for viruses
- isolating infected patients
- completing patient courses
- using targeted treatments
-
Why must patients complete their full course of prescribed antibiotics?
- Speed digestion
- Stop viral growth
- Prevent resistance
- Increase immunity
-
Which industry's use of antibiotics should be restricted to slow resistance?
- pharmaceutical production
- renewable energy
- software engineering
- agriculture
-
Why is discovering new antibiotics not a permanent solution to bacterial resistance?
- medicines become toxic
- bacteria stop mutating
- pathogens lose cell walls
- it is too slow
-
Why should antibiotics never be prescribed to treat the common cold?
- colds are bacterial
- colds are viral
- antibiotics cure colds
- colds are fungal
-
What risk arises when a patient stops taking antibiotics early?
- resistant strains
- viral mutations
- immune failure
- weaker pathogens
-
Why does a bacterial population resistant to a drug rise over time?
- immune cells weaken
- bacteria stop dividing
- antibiotics cure all
- survive and reproduce
-
What process produces new strains of bacterial pathogens?
- mitosis
- osmosis
- respiration
- mutation
-
Why is MRSA a major concern in medicine?
- it lacks DNA
- it stops reproduction
- it only affects plants
- no effective treatment
-
What is the concern regarding agricultural use of antibiotics?
- stops animal digestion
- kills all livestock
- increases resistant strains
- improves crop yield
-
Why is developing new antibiotics slower than bacteria evolving resistance?
- antibiotics are illegal
- bacteria lack genes
- fast reproduction rate
- drugs mutate faster
-
What is the primary benefit of reducing inappropriate antibiotic prescribing?
- increases mutation
- stops viral infections
- kills human cells
- slows resistance
-
Which initial event starts the spread of antibiotic resistance?
- phagocytosis
- mutation
- pasteurisation
- vaccination
-
Why do resistant bacterial strains spread easily through a population?
- no effective treatment
- people are immune
- they are viruses
- antibiotics cure them
-
Which biological principle explains the rise of antibiotic-resistant bacteria?
- active transport
- genetic engineering
- natural selection
- fermentation
