Sec 4 Combined Science (Biology) WA1 practice paper

WA1 is usually the first weighted assessment of the Sec 4 Combined Science (Biology) half, held early in the year. It checks infectious diseases — pathogens, influenza and pneumococcal disease, vaccines, antibiotics and resistance — and the flowering-plant pair of chapters: leaf structure, xylem and phloem, photosynthesis and its rate factors, transpiration and translocation.

What’s tested

Commonly Chapter 1 (infectious diseases in humans) and Chapter 2 (nutrition and transport in flowering plants). Some schools begin Chapter 3. Check your school’s assessment outline for the exact scope.

Section A: Multiple choice[10 marks]

Answer all questions. For each question, write the letter (A, B, C or D) of the correct answer.

  1. 1

    Influenza is caused by

    1. Aa bacterium
    2. Ba virus
    3. Ca toxin
    4. Dinsulin resistance
    ( )
  2. 2

    Which disease is NOT infectious?

    1. Ainfluenza
    2. Bpneumococcal pneumonia
    3. Ctype 2 diabetes
    4. Dthe common cold
    ( )
  3. 3

    Antibiotics are ineffective against influenza because

    1. Athe dose is too small
    2. Binfluenza is viral and antibiotics attack bacterial structures
    3. Cviruses are stronger than bacteria
    4. Dantibiotics only work in hospitals
    ( )
  4. 4

    A vaccine protects by

    1. Akilling pathogens directly
    2. Bstimulating white blood cells to produce antibodies quickly on real infection
    3. Ccoating the airways
    4. Draising body temperature permanently
    ( )

Revision checklist

  • Sort diseases confidently: infectious (influenza, pneumococcal) versus non-infectious (type 2 diabetes).
  • Rehearse the vaccine sequence and the antibiotics-versus-viruses argument, including resistance by selection.
  • Draw the dicot leaf section from memory: layers, stomata, vascular bundles.
  • Keep the pipelines straight: xylem water upward, phloem sucrose both ways.
  • Practise pondweed data: rate falls with the square of lamp distance.
  • Sit the Chapter 1 and Chapter 2 quizzes first, then this paper in one 55-minute block.

Exam tips

  • Vaccine answers need the full sequence — look-alike agent, white blood cells, fast antibodies.
  • Antibiotic questions must name the target: bacterial structures, which viruses lack.
  • Rate questions: quote the data figures before explaining the trend.
  • Define transpiration exactly — water vapour, through the stomata.

Questions about the WA1

What is tested in Sec 4 Combined Science (Biology) WA1?

Most schools test Chapter 1 (infectious diseases: pathogens, influenza and pneumococcal disease, vaccines, antibiotics and resistance) and Chapter 2 (leaf structure, photosynthesis, transpiration, translocation). Your school’s assessment outline gives the exact scope.

How long is the WA1 paper?

Formats vary by school. This practice paper has 40 marks and takes 55 minutes, mixing ten multiple-choice questions with structured questions.

Is this paper based on a real school paper?

No. QuizQuip papers are written from scratch against the Combined Science 5088 Biology component. QuizQuip is not affiliated with MOE or SEAB and does not host school or past examination papers.
