Term 1G2 / G3
Sec 4 Biology WA1 practice paper
WA1 is usually the first weighted assessment of the Sec 4 Biology year, held around the end of Term 1. It tests the regulation block — homeostasis, negative feedback, hormones, the nervous system and the eye — together with the pathogens-and-immunity chapter that pairs with it in the common scheme.

The first questions of Section A, as they appear on the paper.
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( )
Homeostasis is the maintenance of
- Aa constant external environment
- Bbody temperature at 25 °C
- Ca constant internal environment within narrow limits
- Dunchanged blood glucose at all costs
- 2( )
In negative feedback, the corrective mechanism acts
- Ain the opposite direction, cancelling the change
- Bbefore the change is detected
- Cin the same direction as the change
- Donly on the brain
- 3( )
On a cold day, blood flow through the skin capillaries decreases because
- Athe arterioles dilate
- Bsweating increases
- Cshivering stops
- Dthe arterioles constrict
- 4( )
Insulin lowers blood glucose by making the liver
- Abreak down glycogen into glucose
- Bconvert glucose into glycogen
- Crelease glucose into urine
- Dsecrete more insulin
Revision checklist
- Run the negative-feedback loop for three systems aloud: temperature, blood glucose, water (ADH).
- Write the reflex arc and the accommodation rules from memory — receptor to effector, fat lens for near.
- Tabulate the pathogens: bacterial versus viral structure, influenza versus pneumococcal disease.
- Explain vaccination in sequence: resembling agent, antibodies, memory cells, secondary response.
- Sit the Chapter 1–2 quizzes first, then this paper in one 55-minute block.
Exam tips
- Feedback questions: name the stimulus, receptor, control centre and correction — all four, in order.
- Eye questions pair structure with function: ciliary muscles, lens shape and the light’s origin near or far.
- Disease questions: name the pathogen first, then transmission, then route-matched reduction measures.
- Hormone questions: gland, target organ and direction of effect — never swap insulin and glucagon.
Questions about the WA1
What is tested in Sec 4 Biology WA1?
Most schools test Chapters 1–2: homeostasis and negative feedback, temperature regulation, insulin and glucagon, ADH, reflexes and the eye, plus pathogens, vaccination and antibiotic resistance. Your school’s Term 1 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, in the style most schools use for a Biology WA.
