Year 11 SACE Biology practice questions
This public preview page identifies the planned Year 11 SACE Biology demo route and links it to curriculum coverage while the reviewed sample question set is being completed.
Sample-question focus
The planned public sample is for Year 11 SACE Biology practice and will open after the demo questions are reviewed.
Skills covered
Practice cells, living systems, ecosystems, genetics, evolution, biodiversity, disease, biotechnology, and scientific inquiry.
Exercise and test mode
The route is public now; the exercise and test preview will become available after the curated question set is ready.
Curriculum link
Compare this demo with the SACE Year 11-12 Biology curriculum page to scan related topics, subtopics, and pathway coverage.
These sample questions are visible on the page before login. Use them to check the style of the answers and worked explanations, then open the no-login demo for a longer practice set.
practiceSACE Year 11 Biology practice questionsCells and microorganismshardcell transport diagram
1. A membrane diagram shows glucose entering a cell through a transport protein from high to low concentration. Which process is most likely?
Choices
Facilitated diffusion
Binary fission
Translation
Meiosis
Explanation:
Facilitated diffusion uses a membrane protein but still moves down the concentration gradient without direct energy input.
practiceSACE Year 11 Biology practice questionsEnzymeshardenzyme graph
2. An enzyme graph shows rate increasing with substrate concentration before it levels off. Why does the graph level off?
Choices
Active sites become saturated.
The enzyme becomes DNA.
Substrate turns into light.
Products stop existing.
Explanation:
Once most enzyme active sites are occupied, adding more substrate has little effect on reaction rate.

3. An energy pyramid shows 12000 kJ in producers. Using a 10% transfer, how much energy is available at the next trophic level?
Choices
1200 kJ
120 kJ
10800 kJ
12000 kJ
Explanation:
Ten percent of 12000 kJ is 1200 kJ.

4. A cell-cycle diagram shows a checkpoint before DNA synthesis. Why are checkpoints important?
Choices
They help regulate cell division.
They stop all metabolism.
They make enzymes unusable.
They remove all chromosomes.
Explanation:
Checkpoints help ensure cells divide only when conditions and DNA status are suitable.
practiceSACE Year 11 Biology practice questionsPopulation ecologyhardpopulation graph
5. A population graph rises from 20 to 85 before stabilising. What does the stable section most likely indicate?
Choices
Limiting factors are balancing growth.
The population has no organisms.
DNA replication has stopped in every cell.
Food is unlimited forever.
Explanation:
A stable population near carrying capacity suggests resources, predation, or other limits are balancing births and deaths.

6. A graph shows pesticide-resistant insects increasing after repeated pesticide use. Which explanation is best supported?
Choices
Resistant insects had higher survival.
All insects became plants.
The pesticide removed all variation.
Resistance could not be inherited.
Explanation:
Pesticide use selected for insects with resistance, increasing the trait frequency.
For parents checking senior maths readiness
Year 10 practice can help identify whether a student is comfortable with algebra, geometry, trigonometry, statistics, and probability before choosing senior maths pathways. The demo is a quick way to sample those areas without creating an account.

In progress
Year 11 SACE Biology is available to purchase, and the public demo preview is still being prepared.
Students can use the purchased subject once subscribed; this anonymous preview will be opened after the curated public question set is ready.
Does this page include Year 11 SACE Biology practice questions?
Not yet. The Year 11 SACE Biology demo route is public, but the interactive sample questions will open after the reviewed public set is ready.
Can students try the demo without signing up?
No sign-up is required to view the preview status. The no-login interactive demo will be available after the sample set is completed.
How does this demo relate to curriculum coverage?
This demo is linked with the SACE Year 11-12 Biology curriculum coverage page, where parents can compare the broader topic and pathway structure used for Skill Align practice.
