practiceVCE Year 11 Biology practice questionsCell membraneshardcell transport diagram
1. A red blood cell is placed in a hypotonic solution. The membrane model shows water moving through the cell membrane. What is the most likely immediate effect?
Choices
Water moves into the cell by osmosis.
Protein is made at the membrane.
Water moves out by active transport.
The membrane stops all water movement.
Explanation:
A hypotonic solution has a lower solute concentration outside the cell, so water moves into the cell by osmosis.

2. The enzyme-rate graph peaks at pH 7 and is lower at pH 4 and pH 10. Which condition gives the highest enzyme activity?
Choices
pH 7
pH 4
pH 10
All pH values are equal
Explanation:
The peak of the graph shows the optimum condition for this enzyme, so the highest activity is at pH 7.
practiceVCE Year 11 Biology practice questionsEcosystem energyhardecosystem pyramid
3. An energy pyramid shows 5000 kJ in producers and a 10% transfer to the next trophic level. How much energy is available to primary consumers?
Choices
500 kJ
50 kJ
4500 kJ
5000 kJ
Explanation:
About 10% of energy transfers to the next trophic level, so 10% of 5000 kJ is 500 kJ.
practiceVCE Year 11 Biology practice questionsPopulation modelshardpopulation graph
4. A population graph rises quickly and then levels off near 120 individuals. What does the plateau most likely represent?
Choices
The carrying capacity is about 120.
The population is extinct.
Birth rate is always zero.
Resources are unlimited.
Explanation:
A logistic population graph levels off near the carrying capacity when limiting factors balance population growth.

5. The cell-cycle diagram highlights the stage before mitosis. What must occur before one cell divides into two genetically identical cells?
Choices
DNA is replicated.
Chromosomes are destroyed.
Gametes are fertilised.
The membrane becomes a cell wall.
Explanation:
DNA must be copied before mitosis so each daughter cell can receive the same genetic information.

6. A graph shows the dark moth phenotype rising from 25% to 70% over several generations in a polluted habitat. Which explanation is best supported?
Choices
Dark moths had a survival advantage.
All light moths changed colour.
The habitat caused every mutation.
No selection occurred.
Explanation:
The increase in dark phenotype frequency suggests individuals with that phenotype survived and reproduced more successfully in that environment.
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.

A strong way to preview the full Skill Align practice flow
Want more than this sample set?
This public preview is intentionally small. Full access adds more practice sessions, broader topic coverage,
saved student history, and structured learning by year and subject.
Does this page include Year 11 VCE Biology practice questions?
Yes. This public demo includes reviewed Year 11 VCE Biology sample questions so families can preview the Skill Align practice style before regular use.
Can students try the demo without signing up?
Yes. The public demo can be opened without signing up, and the attempt stays in the page instead of being saved to a student record.
How does this demo relate to curriculum coverage?
This demo is linked with the VCE Year 11-12 Biology curriculum coverage page, where parents can compare the broader topic and pathway structure used for Skill Align practice.
