practiceQCE Year 11 Biology practice questionsCells as the basis of lifehardcell transport diagram
1. The diagram shows water leaving a plant cell in a concentrated salt solution. What process is responsible?
Choices
Osmosis
Protein synthesis
Mitosis
Gas exchange
Explanation:
Water moves across the partially permeable membrane from higher water concentration inside the cell to lower water concentration outside.
practiceQCE Year 11 Biology practice questionsEnzymeshardenzyme graph
2. An enzyme graph peaks at 40 C and drops sharply at 70 C. What has most likely happened at 70 C?
Choices
The enzyme has denatured.
The substrate has become DNA.
The enzyme has reproduced.
The reaction has become photosynthesis.
Explanation:
Very high temperature can alter the active site, causing enzyme activity to fall.

3. A cell-cycle model shows DNA copied before nuclear division. Why is this needed?
Choices
Each daughter cell receives a complete genome.
The cell loses all chromosomes.
Only one daughter cell survives.
Proteins stop being made forever.
Explanation:
DNA replication before division ensures each daughter cell receives the genetic information it needs.

4. An energy pyramid shows 3000 kJ in producers and 300 kJ in primary consumers. What energy transfer is represented?
Choices
10%
1%
30%
90%
Explanation:
300 divided by 3000 is 0.10, so the transfer is 10%.
practiceQCE Year 11 Biology practice questionsPopulation ecologyhardpopulation graph
5. A population graph levels off around 240 individuals after rapid early growth. Which term best describes this level?
Choices
Carrying capacity
Extinction point
Fertilisation rate
Allele frequency
Explanation:
The plateau occurs when environmental limits keep the population near carrying capacity.
practiceQCE Year 11 Biology practice questionsAdaptationhardselection graph
6. A graph shows drought-tolerant plants increasing from 18% to 62% after several dry seasons. What is the best interpretation?
Choices
Drought tolerance increased fitness in that environment.
All plants became genetically identical.
Dry weather removed all variation.
The graph shows no change.
Explanation:
The data supports selection for a trait that improved survival and reproduction during dry seasons.
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 QCE Biology practice questions?
Yes. This public demo includes reviewed Year 11 QCE 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 QCE Year 11-12 Biology curriculum coverage page, where parents can compare the broader topic and pathway structure used for Skill Align practice.
