1In phototropism, how does the plant hormone auxin cause a seedling shoot to bend toward a unilateral light source?

A.Auxin migrates to the shaded side of the shoot, stimulating cell elongation on that side.

B.Auxin migrates to the illuminated side of the shoot, inhibiting cell division on that side.

C.Auxin is destroyed by light on the shaded side, causing the illuminated side to grow faster.

D.Auxin concentrates equally on both sides, causing equal swelling of epidermal cells.

Explanation: Unilateral light causes auxin to move laterally from the illuminated side to the shaded side of the shoot tip. High concentrations of auxin promote cell elongation on the shaded side, causing the stem to curve toward the light source.

2Which term describes a plant's directional growth response to physical contact with an object, such as a tendril twining around a support trellis?

A.Thigmonasty

B.Thigmotropism

C.Chemotaxis

D.Gravitropism

Explanation: Thigmotropism is a directional growth response of a plant organ to contact with a solid object. The contact causes differential cell growth, allowing structures like climbing tendrils to wrap around supports.

3A motile unicellular organism swims directly toward a higher concentration of dissolved glucose. How is this orientation behavior classified?

A.Negative chemotaxis

B.Positive chemotaxis

C.Klinokinesis

D.Positive chemotropism

Explanation: Positive chemotaxis is the directional movement of a whole motile organism toward a chemical stimulus, such as a nutrient source like glucose.

4How does orthokinesis differ from klinokinesis in animal orientation responses?

A.Orthokinesis involves a change in the speed of movement, whereas klinokinesis involves a change in the rate of turning.

B.Orthokinesis is a directional response, whereas klinokinesis is a non-directional response.

C.Orthokinesis is mediated by auxin, whereas klinokinesis is mediated by nerve impulses.

D.Orthokinesis involves turning toward light, whereas klinokinesis involves turning away from light.

Explanation: In kinesis, the response is non-directional. Orthokinesis refers to changes in the speed or velocity of movement depending on stimulus intensity, while klinokinesis refers to changes in the frequency or rate of turning.

5What is meant by the 'free-running period' of a circadian rhythm?

A.The duration of activity measured when an organism is exposed to natural 24-hour day-night cycles.

B.The length of the endogenous cycle when an organism is kept under constant environmental conditions without Zeitgebers.

C.The time required for an organism to reset its biological clock after a rapid time-zone transition.

D.The total period during which an animal exhibits seasonal migratory behavior.

Explanation: The free-running period is the intrinsic duration of an endogenous biological rhythm when environmental timing cues (Zeitgebers) such as light and temperature are completely removed. It is typically close to, but not exactly, 24 hours.

6In chronobiology, what is the precise function of a 'Zeitgeber'?

A.An internal gene product that generates the molecular oscillations of the clock.

B.An external environmental cue that entrains an endogenous biological clock to a 24-hour cycle.

C.A hormone released by the pituitary gland to initiate sleep in mammals.

D.A sensory organ in plants that detects the direction of gravitational pull.

Explanation: A Zeitgeber (German for 'time-giver') is an external environmental stimulus—most commonly dawn or dusk light—that synchronizes (entrains) an organism's endogenous biological rhythm to the 24-hour solar cycle.

7Which transition occurs when red light (660 nm) strikes the phytochrome pigment in plant leaves?

A.Pfr is rapidly converted into the inactive Pr form.

B.Pr is rapidly converted into the biologically active Pfr form.

C.Pr is irreversibly broken down by ubiquitin enzymes.

D.Pfr is converted directly into chlorophyll b.

Explanation: Phytochrome exists in two interconvertible forms. Inactive Pr absorbs red light (660 nm) and is rapidly converted into biologically active Pfr, which triggers physiological responses like flowering and seed germination.

8Under what condition will a short-day (long-night) plant initiate flowering?

A.When the duration of continuous darkness exceeds a species-specific critical night length.

B.When the daytime light duration exceeds a critical threshold of 14 hours.

C.When the level of Pfr in leaf cells exceeds the level of Pr at midnight.

D.When a brief pulse of red light interrupts the dark night period.

Explanation: Short-day plants are actually long-night plants. Flowering is triggered when they experience an uninterrupted dark period that exceeds their critical night length, allowing Pfr (which inhibits flowering in short-day plants) to decline below a critical threshold.

9How does the active phytochrome form (Pfr) affect flowering in long-day (short-night) plants?

A.Pfr acts as a promoter of flowering when night length is shorter than the critical night length.

B.Pfr acts as an inhibitor of flowering during short nights.

C.Pfr degrades chlorophyll, forcing the plant into dormancy.

D.Pfr has no effect on flowering in long-day plants, which rely solely on temperature.

Explanation: In long-day plants, Pfr acts as a promoter of flowering. Short nights leave high residual levels of Pfr at the end of the night (due to insufficient time for complete dark reversion to Pr), which stimulates flowering gene transcription.

10Which situation is an example of density-dependent intraspecific competition?

A.A severe winter frost killing 80% of insects regardless of population size.

B.Members of a red deer population competing for limited breeding territories as population density increases.

C.A introduced stoat preying on both kiwi chicks and native skinks.

D.Volcanic ash fallout destroying all vegetation across an island ecosystem.

Explanation: Intraspecific competition occurs between individuals of the same species. It is density-dependent because as population density increases, resource limitation (such as breeding territories or food) intensifies, reducing per capita growth rate.

About the New Zealand Scholarship Biology Exam

The New Zealand Scholarship Biology examination (Standard 93101) tests candidate capacity for high-level critical thinking, integration of complex biological knowledge, and synthesis of ecological, evolutionary, and hominin trends. This 100-question practice bank provides an exhaustive, multi-choice study tool covering topics from Level 8 of the New Zealand Curriculum.

Exam sponsor: NZQA. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

New Zealand Scholarship Biology: Suggested Study Strategy

1Master the phytochrome conversion kinetics (Pr to Pfr in light, Pfr to Pr in dark) and explain how Pfr acts as a promoter or inhibitor in short-day vs long-day plants.

2Understand the chromosomal mechanisms of allopolyploidy, specifically why initial interspecific hybrids are sterile due to lack of homologous chromosome pairing, and how non-disjunction restores fertility by creating homologous pairs.

3Detail the mechanical advantages of bipedal adaptations, linking the valgus angle, bowl-shaped pelvis, and S-shaped spine to energy conservation and bipedal efficiency.

4Compare hominin tool cultures in chronological order (Oldowan -> Acheulean -> Mousterian -> Upper Paleolithic), linking cognitive capacity and brain development to tool complexity.

5Evaluate genetic evidence (mtDNA, Y-DNA, nuclear DNA Neanderthal/Denisovan introgression) to compare the Out of Africa and Multiregional dispersal models.

Frequently Asked Questions
