Year 11 ACT Biology practice questions
This public preview page identifies the planned Year 11 ACT 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 ACT 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 ACT 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.
practiceACT Year 11 Biology practice questionsCellshardcell transport diagram
1. A membrane diagram shows carbon dioxide moving out of a cell from high concentration to low concentration. Which process is shown?
Choices
Diffusion
Active transport
Protein synthesis
Meiosis
Explanation:
Carbon dioxide can move passively down its concentration gradient through the membrane.

2. An enzyme graph rises as temperature increases to 35 C, then falls at 60 C. Which temperature gives the highest rate?
Choices
35 C
5 C
60 C
All temperatures
Explanation:
The graph peak marks the highest rate for this enzyme.

3. A pyramid shows 8000 kJ in producers and 800 kJ at the next level. What does this show?
Choices
About 10% energy transfer
About 90% transfer
No energy loss
Consumers make sunlight
Explanation:
800 is 10% of 8000, so the diagram supports about 10% transfer.

4. A graph shows a yeast population rising quickly and then flattening as nutrients run low. What limits further growth?
Choices
Resource availability
Every cell stops having DNA
The population becomes abiotic
Mutation rate must be zero
Explanation:
Nutrients are a limiting factor that can stop exponential growth and produce a plateau.

5. A diagram shows one cell dividing to form two identical body cells. Which process is represented?
Choices
Mitosis
Meiosis
Fertilisation
Translation
Explanation:
Mitosis produces genetically identical body cells for growth and repair.

6. A graph shows a beak-depth trait becoming more common after several dry seasons with hard seeds. Which statement is best supported?
Choices
The trait improved survival with hard seeds.
All birds had identical beaks.
Seed type cannot affect selection.
The trait was not inherited.
Explanation:
The increase suggests birds with that trait had higher fitness under those conditions.
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 ACT 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 ACT Biology practice questions?
Not yet. The Year 11 ACT 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 ACT Year 11-12 Biology curriculum coverage page, where parents can compare the broader topic and pathway structure used for Skill Align practice.
