Year 12 TAS Biology practice questions
This public preview page identifies the planned Year 12 TAS 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 TAS 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 Tasmania 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.
practiceTASC Year 12 Biology practice questionsDNA and proteinshardprotein-synthesis diagram
1. The model shows DNA code being copied to mRNA. Which process occurs in the nucleus before translation?
Choices
Transcription
Diffusion
Osmosis
Predation
Explanation:
Transcription makes an mRNA copy from a DNA template before translation.

2. A Punnett square shows Ff x Ff. What proportion of offspring are expected to be FF?
Choices
25%
50%
75%
0%
Explanation:
One of the four equally likely boxes is FF.

3. The antibody graph shows a larger response after the second exposure to an antigen. Which immune feature explains this?
Choices
Memory cells
Cell walls
Starch grains
Abiotic factors
Explanation:
Memory cells formed after first exposure help produce a stronger secondary response.
practiceTASC Year 12 Biology practice questionsDiseaseharddisease-spread graph
4. A disease-spread graph shows cases rising more slowly after mask use reduces transmission probability. Which factor changed?
Choices
The rate of successful transmission
The DNA code of every host
The number of chromosomes in all cells
The food-web trophic level
Explanation:
Reducing transmission probability lowers the average number of new cases caused by each infection.

5. A DNA gel shows band B travelling further than band A from the wells. Which band represents the smaller fragment?
Choices
Band B
Band A
The well
Both bands are cells
Explanation:
Smaller DNA fragments travel further through the gel than larger fragments.

6. A feedback loop shows body temperature falling below normal. Which response helps restore temperature?
Choices
Shivering increases heat production.
Sweating increases only.
Insulin destroys heat.
Temperature is not controlled.
Explanation:
Shivering is a negative feedback response that generates heat and helps return body temperature toward normal.
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 TAS 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 TAS Biology practice questions?
Not yet. The Year 12 TAS 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 Tasmania Year 11-12 Biology curriculum coverage page, where parents can compare the broader topic and pathway structure used for Skill Align practice.
