1. A population of rabbits is introduced to an island with abundant food and no natural
predators. Which growth pattern would most likely occur initially?
A) Logistic growth
B) Exponential growth
C) No growth
D) Negative growth
Correct Answer: B
With abundant resources and no limiting factors, populations exhibit exponential growth (J-
shaped curve) until resources become limited or other factors intervene.
2. A student measures the mass of an object three times and obtains readings of 2.45 g, 2.47
g, and 2.46 g. The actual mass is 2.50 g. Which statement best describes these
measurements?
, Page 2 of 174
A) They are both accurate and precise
B) They are accurate but not precise
C) They are precise but not accurate
D) They are neither accurate nor precise
Correct Answer: C
The readings are consistent with each other (precise) but consistently lower than the actual
value (not accurate). Precision refers to reproducibility; accuracy refers to closeness to the true
value.
3. Which of the following represents the balanced chemical equation for the combustion of
methane (CH₄) in oxygen?
A) CH₄ + O₂ → CO₂ + H₂O
B) CH₄ + 2O₂ → CO₂ + 2H₂O
C) CH₄ + O₂ → CO₂ + 2H₂O
D) 2CH₄ + 3O₂ → 2CO₂ + 4H₂O
, Page 3 of 174
Correct Answer: B
Balanced equation: CH₄ + 2O₂ → CO₂ + 2H₂O. There are 4 hydrogen atoms on each side and 4
oxygen atoms on each side.
4. A student solves the equation 2x + 5 = 13 and obtains x = 4. Which property of equality did
the student use to isolate the variable?
A) Addition Property of Equality
B) Subtraction Property of Equality
C) Multiplication Property of Equality
D) Division Property of Equality
Correct Answer: B
To solve 2x + 5 = 13, the student subtracts 5 from both sides: 2x = 8. This uses the Subtraction
Property of Equality.
5. Which of the following is the best example of a physical change?
, Page 4 of 174
A) Iron rusting
B) Wood burning
C) Ice melting
D) Milk souring
Correct Answer: C
Ice melting is a physical change—the substance changes state from solid to liquid but its
chemical composition (H₂O) remains unchanged.
6. In a food web, which organisms are classified as primary consumers?
A) Producers (plants)
B) Herbivores
C) Carnivores
D) Decomposers
Correct Answer: B
Primary consumers are herbivores that eat producers (plants). They occupy the second trophic
level in a food chain or web.
