practice WACE Year 11 Biology practice questions Cells hard cell transport diagram

1. The membrane model shows oxygen moving from high concentration outside a cell to lower concentration inside without energy input. Which process is shown?

Choices

Diffusion
Active transport
Mitosis
Translation

Explanation:

Diffusion is passive movement down a concentration gradient.

practice WACE Year 11 Biology practice questions Enzyme function hard enzyme graph

2. An enzyme graph shows low activity at pH 2 and a maximum near pH 8. Which pH is closest to the optimum?

Choices

pH 8
pH 2
pH 12
All pH values

Explanation:

The optimum is where the graph reaches its highest reaction rate.

practice WACE Year 11 Biology practice questions Ecosystem structure hard ecosystem pyramid

3. A biomass pyramid narrows from producers to top consumers. What does this usually show?

Choices

Less biomass is available at higher trophic levels.
Top consumers are producers.
Energy increases at every level.
Food webs have no feeding links.

Explanation:

Energy losses between trophic levels usually support less biomass at higher levels.

practice WACE Year 11 Biology practice questions Population change hard population graph

4. A population graph levels near 60 after food becomes limiting. What does the graph suggest?

Choices

The environment supports about 60 individuals.
The species has no births.
The population is always doubling.
Selection cannot occur.

Explanation:

The plateau suggests the population has reached carrying capacity under those conditions.

practice WACE Year 11 Biology practice questions Cell division hard cell-cycle diagram

5. A cell-cycle diagram shows chromosomes lining up and then separating to opposite poles. Which process is being completed?

Choices

Mitosis
Transcription
Digestion
Osmosis

Explanation:

Chromosome alignment and separation are key stages of mitosis.

practice WACE Year 11 Biology practice questions Adaptation hard selection graph

6. A graph shows a heat-tolerant phenotype increasing after several hotter summers. Which conclusion is best supported?

Choices

Heat tolerance improved reproductive success.
All individuals had equal survival.
Temperature cannot affect populations.
The trait disappeared.

Explanation:

The rising frequency supports selection favouring heat-tolerant individuals 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.
