Biology at Year 10: what the curriculum expects

Year 10 biology covers DNA, genes and inheritance, evolution by natural selection and the evidence for it.

This topic sits inside the Victorian Curriculum for Year 10 science; the questions stay at the easy and at-level tiers so the result is a fair check of the foundations.

Common biology misconceptions tutors see

The distractors in this quiz are built from real misconceptions rather than random wrong numbers, so a specific wrong answer usually points to a specific gap. The ones we see most at Year 10:

• Evolution is described as animals wanting to change.
• Dominant alleles are believed to be more common.
• Hormones and nerves are treated as the same system.

None of these is a sign of low ability. Each is a reasonable idea that worked in an earlier year and needs replacing, which is exactly what a good explanation, or a tutor, does.

Practising biology with a Year 10 student

The habits that move biology from shaky to secure at Year 10:

1. Practise Punnett squares.
2. Explain natural selection for a specific example.
3. Compare the nervous and endocrine systems in a table.

Secondary science relies on terminology and on explaining results with the right concept. Make summary notes, draw diagrams from memory and practise written explanations.

How the 10 questions are chosen

Every set on this page is a seeded selection of 10 from the 26 biology questions that pass our quality gate. A different seed gives a different set, and there are many more combinations than any one student will need. The correct answers never appear in the page source; the browser asks our server for them after you press Mark my answers.

A single-topic quiz is more precise than a mixed one: if the score here is low, the gap is in biology, not somewhere in Year 10 science generally. It is still short, though, and it cannot show how a student copes with the stretch and challenge questions that decide a top result. That is what the free Skills Check adds.

Question 1

Biology

Characteristics passed from parents to offspring are due to…

Genes Enzymes Vitamins Hormones only

Question 2

Biology

A researcher finds that a particular enzyme works fastest at 37 °C and pH 7. She then heats the enzyme to 80 °C for 10 minutes, cools it back to 37 °C, and tests its activity again. The enzyme shows almost no activity at 37 °C. Which explanation BEST accounts for this result?

Heating permanently changed the enzyme's three-dimensional shape, so substrate can no longer bind to the active site. The substrate was broken down during heating, so there is nothing left for the enzyme to act on. Cooling the enzyme back to 37 °C destroyed the active site by reforming incorrect bonds. Heating caused the enzyme to run out of ATP, so it can no longer catalyse the reaction.

Question 3

Biology

A student examines two species of Darwin's finches. Species A has a short, strong beak and eats hard seeds. Species B has a long, thin beak and eats insects in bark crevices. Both species live on the same island. A biologist says they evolved from a single ancestral finch species. Which combination of processes best explains how two species with such different beaks arose from one ancestor?

Genetic variation in the ancestral population, followed by natural selection favouring different beak shapes for different food sources, leading to reproductive isolation and speciation. The island's two food sources each produced chemicals that directly caused beak mutations suited to that food. Random mutation produced finches with different beaks, and all mutant forms survived equally regardless of their environment. The ancestral finches chose to change their beaks by repeatedly using them differently, and this change was inherited by offspring.

Question 4

Biology

What is the powerhouse of the cell (releases energy)?

Chloroplast Nucleus Mitochondria Ribosome

Question 5

Biology

In a stable forest ecosystem, the population of a herbivore stays roughly constant over many years, even though each female produces dozens of offspring per year. Which statement BEST explains why the population remains stable?

The herbivore evolves to produce fewer offspring each generation to balance the ecosystem. Most offspring die due to predation, disease, or lack of resources before they reproduce. The herbivore's reproductive rate slows automatically when the population reaches its maximum size. Photosynthesis in the forest decreases each year, limiting the number of herbivores that can exist.

Question 6

Biology

In a food web, energy is lost between trophic levels mainly as:

Additional sunlight Extra oxygen gas New DNA molecules Heat from respiration and life processes

Question 7

Biology

Photosynthesis mainly occurs in which part of the plant cell?

Nucleus Chloroplast Vacuole Mitochondrion

Question 8

Biology

Which kingdom do mushrooms belong to?

Fungi Bacteria Plants Animals

Question 9

Biology

A biologist compares the DNA sequences of a gene found in humans, chimpanzees, dogs, and fish. The results show humans and chimpanzees share 98% of the sequence, humans and dogs share 85%, and humans and fish share 60%. Which conclusion is best supported by this evidence ALONE?

A greater percentage of shared DNA means the species are identical in appearance. Humans and chimpanzees share a more recent common ancestor than humans and fish do. Dogs are more closely related to fish than to humans. Humans evolved directly from chimpanzees.

Question 10

Biology

Where is genetic information stored in a cell?

Ribosome only Cell wall Cytoplasm DNA

How to read a score out of 10

9 or 10 out of 10

The easy and at-level content is secure. The useful question now is how far above the year level the student can go, which a ten-item quiz cannot show. The free Skills Check adds stretch and challenge questions on every topic so you can see the ceiling as well as the floor.

7 or 8 out of 10

Solid, with one or two specific gaps. Look at which topic the incorrect answers came from (the results panel names the weakest topic) and spend a week on that topic before re-testing with a different seed.

5 or 6 out of 10

Some core ideas are shaky. The pattern matters more than the score: two misses in the same topic is a gap; misses scattered across topics usually means reading the question too fast. Either way, the Skills Check will tell you which.

4 or fewer out of 10

Foundations from an earlier year are probably missing, which is common and fixable. Try the quiz one year level down to confirm, then talk to a tutor about a short catch-up plan rather than more of the same practice.
