Year 12 WACE Biology practice questions
This public preview page identifies the planned Year 12 WACE 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 12 WACE 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 WA 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.

1. The protein-synthesis model shows mRNA codon UUU. Which amino acid information carrier is read at the ribosome?
Choices
mRNA codon
Cell membrane lipid
Antibody only
Starch molecule
Explanation:
The ribosome reads mRNA codons during translation to assemble a polypeptide.

2. A Punnett square shows TT x tt. What genotype will all offspring have?
Choices
Tt
TT
tt
Tt and tt equally
Explanation:
Each offspring receives T from one parent and t from the other, so all are heterozygous Tt.

3. A transmission graph shows cases rising while each case infects more than one new person on average. Which value best describes this situation?
Choices
R is greater than 1.
R equals 0 only.
R is below 1.
R cannot affect cases.
Explanation:
If each infected person infects more than one new person on average, case numbers can increase.

4. An immune diagram shows antibodies binding to a specific antigen shape. Which statement best explains specificity?
Choices
Antibody binding sites match particular antigens.
Antibodies bind all molecules equally.
Antigens are always enzymes.
Red blood cells make antibodies.
Explanation:
The shape of an antibody binding site determines which antigen it binds most effectively.

5. A DNA gel shows a child band pattern that must include one matching band from each parent. Which lane best supports Parent B?
Choices
Lane B
Lane A only
The marker ladder
No lane
Explanation:
Inheritance evidence in a gel profile is supported when child bands can be accounted for by the parent lanes.

6. A selection graph shows allele B increasing from 0.30 to 0.55 over generations. Which statement is best supported?
Choices
Allele B became more common.
Allele B disappeared.
All alleles stayed equal.
The graph shows protein synthesis only.
Explanation:
The frequency increased from 0.30 to 0.55, so allele B became more common in the population.
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 12 WACE 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 12 WACE Biology practice questions?
Not yet. The Year 12 WACE 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 WA Year 11-12 Biology curriculum coverage page, where parents can compare the broader topic and pathway structure used for Skill Align practice.
