1. Which of the following sentences is the most correct in terms of style, clarity, and punctuation?

• A. The possible side effects of the medication that the doctor had prescribed for her were a concern for Lucinda, and she continued to take the medication.
• B. The medication that the doctor prescribed had side effects concerning Lucinda, who continued to take it.
• C. Lucinda was concerned about side effects from the medication that her doctor had prescribed, so she continued to take it.
• D. Although Lucinda was concerned about the possible side effects, she continued to take the medication that her doctor had prescribed for her.

Correct answer: D

Rationale: Choice D is the most appropriate sentence in terms of style, clarity, and punctuation. It maintains parallel structure in the sentence by using 'Although Lucinda was concerned about the possible side effects, she continued to take the medication that her doctor had prescribed for her.' This choice effectively conveys the cause and effect relationship between Lucinda's concern about side effects and her decision to continue taking the medication. Choices A, B, and C have issues with subject-verb agreement, awkward phrasing, or lack of clarity in expressing the relationship between Lucinda's concern and her action, making them less correct compared to Choice D.

2. What is the primary function of lymph nodes, small, bean-shaped structures found along lymphatic vessels?

• A. To store excess lymph fluid
• B. To produce red blood cells
• C. To filter lymph and fight infection
• D. To transport lymph to the heart

Correct answer: C

Rationale: Lymph nodes primarily function to filter lymph and fight infection. They contain immune cells that help to remove pathogens and foreign particles from the lymph fluid as it passes through the nodes. This process helps to activate the immune response and defend the body against infections. Choice A is incorrect as lymph nodes do not store excess lymph fluid; they filter lymph. Choice B is incorrect as the production of red blood cells primarily occurs in the bone marrow, not in lymph nodes. Choice D is incorrect as lymph nodes do not transport lymph to the heart; they filter and process lymph to remove impurities and activate the immune response.

3. How many electrons are typically found in each shell of a neutral aluminum atom with 13 electrons in its electron cloud?

• A. 6 in the first shell, 7 in the second shell
• B. 2 in the first shell, 11 in the second shell
• C. 2 in the first shell, 8 in the second shell, 3 in the third shell
• D. 3 in the first shell, 5 in the second shell, 5 in the third shell

Correct answer: C

Rationale: In a neutral aluminum atom with 13 electrons, the electron distribution typically follows the electron shell filling order based on the Aufbau principle. The first shell can hold a maximum of 2 electrons, the second shell can hold up to 8 electrons, and the third shell can hold up to 8 electrons as well. Therefore, the distribution would be 2 electrons in the first shell, 8 electrons in the second shell, and 3 electrons in the third shell, totaling 13 electrons. Choice A is incorrect as it exceeds the maximum number of electrons the shells can hold. Choice B is incorrect as it does not distribute the electrons correctly among the shells. Choice D is incorrect as it also does not distribute the electrons correctly among the shells.

4. Which term describes the allele for green eyes?

• A. Dominant
• B. Recessive
• C. Homozygous
• D. Heterozygous

Correct answer: B

Rationale: The correct answer is 'B: Recessive.' In genetics, eye color is determined by multiple genes, with green eyes often being associated with a recessive allele. When an individual carries two copies of the recessive allele for green eyes, they will express this eye color. Dominant alleles are expressed over recessive alleles. Homozygous refers to having two identical alleles for a particular gene, and heterozygous refers to having two different alleles. In this context, the allele for green eyes is recessive, meaning it is expressed only when an individual carries two copies of this specific allele. Therefore, 'Recessive' is the most appropriate term to describe the allele for green eyes, making it the correct answer.

5. Which of the following spellings is correct?

• A. Dependant
• B. Dependent
• C. Dependunt
• D. Dependent

Correct answer: D

Rationale: The correct spelling is 'dependent,' meaning someone who relies on another for support. Choice A, 'Dependant,' is a common misspelling. Choice B, 'Dependint,' is incorrect. Choice C, 'Dependunt,' is also incorrect. Therefore, the correct answer is 'Dependent.'
