1. Which sentence uses the semicolon correctly?

• A. The play was long; however, it was very entertaining.
• B. The guests arrived; Sarah greeted them at the door.
• C. John likes apples; Mary prefers oranges.
• D. He was tired; he went to bed early.

Correct answer: B

Rationale: Option B correctly uses a semicolon to join two independent clauses related to the same event. In this sentence, 'The guests arrived' and 'Sarah greeted them at the door' are both independent clauses that are appropriately connected using a semicolon. Choice A incorrectly uses a semicolon before 'however,' which is a conjunction that should be preceded by a comma. Choice C incorrectly uses a semicolon to connect two independent clauses that are not closely related. Choice D incorrectly uses a semicolon to connect two independent clauses without a clear relationship or cohesion.

2. Which element shares the same group (family) on the periodic table with helium (He)?

• A. Neon (Ne)
• B. Boron (B)
• C. Carbon (C)
• D. Oxygen (O)

Correct answer: A

Rationale: Neon (Ne) shares the same group (family) on the periodic table with helium (He). Both helium and neon belong to Group 18 (Noble Gases) due to their complete and stable outer electron shells, making them chemically inert. Boron (B), Carbon (C), and Oxygen (O) are not in the same group as helium. Boron is in Group 13, Carbon is in Group 14, and Oxygen is in Group 16 on the periodic table.

3. Are red hair and a height of six feet part of an individual's genotype or phenotype?

• A. Red hair is part of the phenotype; height is part of the genotype.
• B. Red hair is part of the genotype; height is part of the phenotype.
• C. Both characteristics describe his genotype.
• D. Both characteristics describe his phenotype.

Correct answer: D

Rationale: In the context of genetics, genotype refers to an individual's genetic makeup, while phenotype refers to the observable characteristics resulting from the interaction of the genotype with the environment. Red hair and a height of six feet are observable characteristics, making them part of the individual's phenotype. Therefore, both red hair and height are aspects of the individual's phenotype. Choices A and B are incorrect as they incorrectly assign one characteristic to the genotype and the other to the phenotype, which is not accurate. Choice C is incorrect as it states that both characteristics describe the genotype, which is inaccurate as they are observable traits. The correct answer is D, as both red hair and height are observable traits or characteristics, falling under the definition of phenotype in genetics.

4. Which word is spelled correctly?

• A. Accommodate
• B. Acquiesce
• C. Perceive
• D. Dilemma

Correct answer: B

Rationale: The correct spelling for the word 'to submit or agree without protest' is 'acquiesce,' making option B the correct choice. Choice A, 'Accommodate,' refers to providing lodging or fitting in with someone's needs. Choice C, 'Perceive,' means to become aware or conscious of something. Choice D, 'Dilemma,' is a situation requiring a choice between equally undesirable alternatives. Therefore, options A, C, and D are spelled correctly but are not the correct answer based on the definition provided in the question.

5. Convert 0.025 mg to micrograms.

• A. 25 mcg
• B. 250 mcg
• C. 2.5 mcg
• D. 0.25 mcg

Correct answer: A

Rationale: To convert milligrams to micrograms, you multiply by 1000, not 10000. Therefore, 0.025 mg equals 25 mcg. Choice B (250 mcg) is incorrect as it incorrectly multiplies by 10000. Choice C (2.5 mcg) is incorrect as it incorrectly divides by 10. Choice D (0.25 mcg) is incorrect as it incorrectly multiplies by 10.
