What does immunity refer to in the human body?
  • Natural ability to fight diseases
  • Ability to digest complex foods
  • Capacity to grow muscles quickly
  • Skill to control body temperature
How do vaccines help the immune system protect against disease?
  • They train recognition and attack of pathogens
  • They increase blood pressure and pulse rate
  • They stop hormones from acting in tissues
  • They replace all white blood cells instantly
Which statement correctly describes acquired immunity from vaccination?
  • Defense present from birth without any exposure
  • Immunity that only lasts for one single day
  • Protection developed after exposure to a pathogen
  • Resistance created by drinking extra water
Which example shows how an inactivated component vaccine works?
  • Tetanus shot with inactivated bacterial toxin
  • Antibiotics that kill active bacteria directly
  • Vitamin tablets improving general metabolism
  • Painkillers reducing swelling after sprains
What key observation led Edward Jenner toward the first vaccine?
  • Children with measles always developed mumps
  • People with flu recovered faster in winter
  • Farmers exposed to pollen were never sick
  • Milkmaids with cowpox did not get smallpox
Which sequence matches Jenner’s scientific method steps?
  • Observation, hypothesis, experimentation, results
  • Experimentation, results, observation, hypothesis
  • Results, observation, experimentation, hypothesis
  • Hypothesis, results, observation, experimentation
Why did mass vaccination campaigns in the 1960s–1970s matter for smallpox?
  • They made cowpox infections more common
  • They slightly increased annual case counts
  • They led to global eradication by 1979
  • They shifted smallpox only to cold regions
Which statement best describes what antibiotics do in the body?
  • They kill bacteria causing infections
  • They boost immunity against all germs
  • They neutralize toxins from protozoa
  • They cure viral diseases like flu
Which infection type should NOT be treated with antibiotics?
  • Skin boil caused by bacteria
  • Common cold caused by viruses
  • Typhoid caused by bacteria
  • Strep throat caused by bacteria
What is antibiotic resistance?
  • Protozoa change into bacterial forms
  • Viruses stop entering human cells
  • Humans become immune to all antibiotics
  • Bacteria survive and multiply despite an antibiotic
In the community diagram, which pathway spreads resistant bacteria from farms to people?
  • Through direct contact with protozoa
  • Through wind carrying viral droplets
  • Through solar light on crop leaves
  • Through animal food products like meat or butter
According to the infographic, what hospital-related factor can spread resistant bacteria?
  • Lack of protozoa in hospitals
  • Use of antiviral vaccines only
  • Excess oxygen in patient rooms
  • Dirty surfaces or healthcare workers
Why can taking antibiotics when they are not required be harmful?
  • It reduces immunity against all microbes
  • It turns antibiotics into vaccines over time
  • It instantly cures viral fevers more quickly
  • It helps resistant bacteria grow and take over
Which precaution helps reduce antibiotic resistance, as shown in the panels?
  • Stop treatment after first relief
  • Give routine shots to cattle
  • Share leftover pills with family
  • Use only with a doctor’s prescription
What happens when antibiotics kill harmful bacteria along with good bacteria?
  • Protozoa replace all gut microbes
  • Human cells become resistant to drugs
  • Viruses immediately mutate into bacteria
  • A few microbes develop resistance
Which sequence best explains one route of resistant bacteria spreading shown in the community diagram?
  • Animals develop resistance, products expose people, community spread
  • Vaccines kill viruses, hospitals clean surfaces, no spread
  • Plants release antivirals, wind stops microbes, fewer cases
  • People take vitamins, protozoa vanish, infection ends
Which statement best defines health for overall well-being?
  • Having strong muscles and stamina only
  • Complete physical, mental, social well-being
