1. When it gets warm in the spring, _______ and _______ like to go fishing at Cobbs Creek. Which of the following word pairs should be used in the blanks above?

• A. me, him
• B. he, I
• C. him, I
• D. he, me

Correct answer: C

Rationale: The correct word pair to use in this context is 'him, I.' This is because 'him' and 'I' are the correct pronouns to refer to two individuals in the third person (him) and first person (I). The sentence should indicate that when it gets warm in the spring, 'him' and 'I' like to go fishing at Cobbs Creek. Choice A, 'me, him,' is incorrect as 'me' should be replaced with 'I' to maintain proper subject-object agreement. Choice B, 'he, I,' is incorrect as 'he' should be replaced with 'him' to properly refer to the other person involved. Choice D, 'he, me,' is incorrect as 'me' should be replaced with 'I' to maintain the correct pronoun usage.

2. What type of sentence is the following example an illustration of?

• A. Compound
• B. Simple
• C. Complex
• D. Compound-Complex

Correct answer: D

Rationale: The sentence provided is classified as compound-complex. It contains two independent clauses ('Although I wished it were summer' and 'I accepted the change of seasons') and one dependent clause ('and I started to appreciate the fall'). A compound sentence joins two independent clauses with a coordinating conjunction, a complex sentence consists of an independent clause and at least one dependent clause, while a compound-complex sentence combines elements of both by having multiple independent clauses and at least one dependent clause. Therefore, choices A, B, and C are incorrect as they do not accurately describe the structure of the sentence.

3. Which of the following quantities do catalysts alter to control the rate of a chemical reaction?

• A. Substrate energy
• B. Activation energy
• C. Inhibitor energy
• D. Promoter energy

Correct answer: B

Rationale: The correct answer is B: Activation energy. Catalysts function by reducing the activation energy needed for a chemical reaction to proceed. By lowering the activation energy, catalysts facilitate the reaction without being consumed themselves. Substrate energy, inhibitors, and promoters are not directly altered by catalysts in the same way activation energy is. Substrate energy refers to the energy of the reactants, which is not altered by catalysts. Inhibitors increase the activation energy required for a reaction, while promoters enhance the effectiveness of a catalyst but do not represent a quantity altered by catalysts.

4. Which of the following represents the three main parts of a neuron?

• A. effector, cell body, axon
• B. dendrites, axon, cell body
• C. dendrites, axon, receptor
• D. synapse, axon, cell body

Correct answer: B

Rationale: A neuron consists of three main parts: dendrites, axon, and cell body. Dendrites receive signals from other neurons or sensory receptors. The cell body (soma) contains the nucleus and organelles essential for neuron function. The axon transmits electrical impulses away from the cell body to other neurons, muscles, or glands. Choice A is incorrect because an effector is not a part of a neuron. Choice C is incorrect because a receptor is not a component of a neuron but rather interacts with neurons. Choice D is incorrect because the synapse is a junction between neurons for signal transmission, not a structural part of a neuron.

5. Scientists compare the DNA of different organisms to understand evolutionary relationships. What is this type of evidence called?

• A. Morphological evidence (comparing body structures)
• B. Biochemical evidence (comparing molecules like proteins)
• C. Geographic distribution evidence (where organisms live)
• D. Genetic evidence (comparing DNA sequences)

Correct answer: D

Rationale: A) Morphological evidence involves comparing body structures of organisms, which can provide information about evolutionary relationships based on physical similarities and differences. However, DNA comparison is a more direct and accurate method for understanding evolutionary relationships. B) Biochemical evidence involves comparing molecules like proteins, which can also provide insights into evolutionary relationships. However, DNA comparison is considered more reliable due to the direct relationship between DNA sequences and genetic information. C) Geographic distribution evidence refers to where organisms live and how their distribution may provide clues about evolutionary history. While this can be informative, it is not as direct or specific as comparing DNA sequences. D) Genetic evidence involves comparing DNA sequences of different organisms to understand their evolutionary relationships. DNA comparison is a powerful tool in evolutionary biology because it provides direct information about genetic similarities and differences, offering precise insights into evolutionary relationships.
