Year 11 HSC Biology practice questions
This public preview page identifies the planned Year 11 HSC 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 HSC 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 HSC 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.
practiceHSC Year 11 Biology practice questionsCell transporthardcell transport diagram
1. The membrane diagram shows ions moving from low concentration to high concentration through a protein pump. Which process is shown?
Choices
Active transport
Simple diffusion
Osmosis only
Photosynthesis
Explanation:
Movement against a concentration gradient through a membrane protein requires energy, so it is active transport.
practiceHSC Year 11 Biology practice questionsEnzyme activityhardenzyme graph
2. An enzyme-rate graph peaks at 37 C and falls at 55 C. What is the best explanation for the lower rate at 55 C?
Choices
The enzyme is denatured.
The enzyme has become a product.
Substrate concentration must be zero.
The reaction has no activation energy.
Explanation:
High temperature can change the enzyme's active-site shape, reducing substrate binding and reaction rate.

3. The cell-cycle diagram shows one parent cell forming two daughter cells with the same chromosome number. Which division process is represented?
Choices
Mitosis
Meiosis
Fertilisation
Mutation
Explanation:
Mitosis produces genetically identical daughter cells for growth and repair.

4. A selection graph shows a bacterial population becoming mostly resistant after repeated antibiotic exposure. What is the best explanation?
Choices
Resistant bacteria survived and reproduced.
All bacteria tried harder to survive.
Antibiotics created every resistance gene on demand.
No variation existed before treatment.
Explanation:
Antibiotic exposure selects for existing resistant variants, increasing their frequency over generations.

5. A food-web pyramid shows 9000 kJ at producers and 900 kJ at herbivores. What percentage transfer is represented?
Choices
10%
1%
90%
100%
Explanation:
The transfer is 900 / 9000 x 100% = 10%.

6. A population graph rises and then levels near 80 individuals after resources become limiting. What does the level section represent?
Choices
Carrying capacity
Extinction
Mutation rate
A food chain
Explanation:
The level section shows the population stabilising near the environment's carrying capacity.
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 HSC 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 HSC Biology practice questions?
Not yet. The Year 11 HSC 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 HSC Year 11-12 Biology curriculum coverage page, where parents can compare the broader topic and pathway structure used for Skill Align practice.
