Year 11 QCE Biology practice questions

This public preview page identifies the planned Year 11 QCE 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 QCE 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 QCE 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.

practice QCE Year 11 Biology practice questions Cells as the basis of life hard cell transport diagram

1. The diagram shows water leaving a plant cell in a concentrated salt solution. What process is responsible?

QCE 11 plant-cell osmosis model inside outside water out
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.

practice QCE Year 11 Biology practice questions Enzymes hard enzyme graph

2. An enzyme graph peaks at 40 C and drops sharply at 70 C. What has most likely happened at 70 C?

QCE 11 enzyme temperature graph 40 C 70 C rate
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.

practice QCE Year 11 Biology practice questions Multicellular systems hard cell-cycle diagram

3. A cell-cycle model shows DNA copied before nuclear division. Why is this needed?

QCE 11 cell-cycle DNA copy S phase mitosis DNA copy
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.

practice QCE Year 11 Biology practice questions Ecosystems hard ecosystem pyramid

4. An energy pyramid shows 3000 kJ in producers and 300 kJ in primary consumers. What energy transfer is represented?

QCE 11 ecosystem transfer model 3000 300 10%
Choices
  • 10%
  • 1%
  • 30%
  • 90%
Explanation:

300 divided by 3000 is 0.10, so the transfer is 10%.

practice QCE Year 11 Biology practice questions Population ecology hard population graph

5. A population graph levels off around 240 individuals after rapid early growth. Which term best describes this level?

QCE 11 population plateau time 240 K
Choices
  • Carrying capacity
  • Extinction point
  • Fertilisation rate
  • Allele frequency
Explanation:

The plateau occurs when environmental limits keep the population near carrying capacity.

practice QCE Year 11 Biology practice questions Adaptation hard selection graph

6. A graph shows drought-tolerant plants increasing from 18% to 62% after several dry seasons. What is the best interpretation?

QCE 11 drought tolerance graph Gen 1 Gen 5 tolerant %
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.

QCE Biology practice questions FAQ

Does this page include Year 11 QCE Biology practice questions?

Not yet. The Year 11 QCE 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 QCE Year 11-12 Biology curriculum coverage page, where parents can compare the broader topic and pathway structure used for Skill Align practice.
