,Section A - Number Sense AND Operations
Q1.
In a population of beetles, color is controlled by a single gene with two alleles: B (brown)
and b (green). In a large population, the frequency of the brown allele is 0.7. Assuming
Hardy-Weinberg equilibrium, what is the expected frequency of heterozygous individuals
after one generation of random mating?
A. 0.21 B. 0.42
C. 0.49 D. 0.70
Correct: B - 0.42
Rationale:Under Hardy-Weinberg, heterozygote frequency is 2pq = 2(0.7)(0.3) = 0.42. Option
A (0.21) is q^2, option C (0.49) is p^2, and option D (0.70) is the allele frequency p, not the
genotype frequency.
Q2.
A student places a sealed glass jar containing a small potted plant and a lit candle on a
balance. The candle burns for 10 seconds and then goes out. During the burning, the
balance reading remains constant. Which statement best explains the observation?
A. The mass of oxygen consumed equals B. The system is closed, so mass is
the mass of carbon dioxide produced, so no conserved regardless of chemical reactions.
net change.
C. The candle consumes oxygen but D. The plant absorbs carbon dioxide and
produces water vapor that condenses, releases oxygen, compensating for the
balancing the mass. candle's consumption.
Correct: B - The system is closed, so mass is conserved regardless of chemical reactions.
Rationale:In a closed system, mass is conserved because no matter enters or leaves. The
chemical reactions (combustion, photosynthesis) only rearrange atoms. Option A is false
because oxygen and carbon dioxide have different molar masses; option C is not generally
true; option D is irrelevant as the plant's net gas exchange is minimal over 10 seconds.
Q3.
A geologist finds a sequence of sedimentary rock layers with a basalt dike cutting across
all layers. A sample from the dike yields a radiometric age of 50 million years. What can be
concluded about the age of the sedimentary layers?
A. The sedimentary layers are all older than B. The sedimentary layers are all younger
50 million years. than 50 million years.

, Section A - Number Sense AND Operations
C. The sedimentary layers are exactly 50 D. The sedimentary layers cannot be dated
million years old. relative to the dike.
Correct: A - The sedimentary layers are all older than 50 million years.
Rationale:According to the principle of cross-cutting relationships, the dike must be younger
than the rocks it cuts. Therefore, all sedimentary layers are older than 50 million years.
Options B and C are incorrect; option D is false because relative dating is possible.
Q4.
A teacher asks students to design an experiment to test the effect of light intensity on the
rate of photosynthesis in Elodea. Which set of variables should be kept constant?
A. Temperature, carbon dioxide B. Light intensity, water temperature, and
concentration, and light wavelength. number of plants.
C. Oxygen production, time of day, and pH D. Light duration, plant size, and type of light
of water. bulb.
Correct: A - Temperature, carbon dioxide concentration, and light wavelength.
Rationale:To isolate the effect of light intensity, other factors affecting photosynthesis
(temperature, CO2 concentration, light wavelength) must be controlled. Option A lists
appropriate constants. Light intensity (B) is the independent variable, not constant. Oxygen
production (C) is the dependent variable. Light duration (D) should also be constant, but the
set is incomplete.
Q5.
A ball is thrown vertically upward from the ground with an initial speed of 20 m/s.
Neglecting air resistance, what is the total time the ball spends in the air? (Use g = 10
m/s²)
A. 2 s B. 4 s
C. 8 s D. 10 s
Correct: B - 4 s
Rationale:Time to reach maximum height: v = u - gt => 0 = 20 - 10t => t = 2 s. Total time = 2
* 2 = 4 s. Option A is only one-way time; options C and D are miscalculations.
Q6.
Which of the following best describes the primary role of the Calvin cycle in
photosynthesis?
A. Splitting water molecules to release B. Generating ATP and NADPH using light
oxygen. energy.
