1. What is the term for an organism with two different alleles for a gene?

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

Correct answer: B

Rationale: Homozygous refers to an organism with two identical alleles for a gene, either both dominant or both recessive. Heterozygous, the correct answer, refers to an organism with two different alleles for a gene, one dominant and one recessive. Dominant and recessive describe the relationship between alleles, where dominant alleles are expressed over recessive alleles in heterozygous individuals. Therefore, the term for an organism with two different alleles for a gene is 'heterozygous.'

2. Which of the following describes the term allele?

• A. A specific form of a gene that can exist at a particular locus
• B. An inheritable variation of a gene
• C. A grouping of various genes
• D. Variations of complementary base pairs

Correct answer: B

Rationale: The correct answer is B. Alleles are different forms of a gene that can exist at a specific locus. They represent variations of a gene and are inheritable. Choice A is incorrect as it does not fully capture the concept of an allele, which is a specific form of a gene rather than a substitution. Choice C is incorrect as alleles are not a grouping of various genes but rather different forms of a single gene at a specific locus. Choice D is also incorrect as it does not accurately describe alleles; alleles are variations of genes, not base pairs.

3. Select the pronoun that could be used in the following sentence: Mrs. Sato, _______ lives down the street, is 99 years old.

• A. she
• B. who
• C. which
• D. whom

Correct answer: B

Rationale: The correct answer is 'B' - 'who.' 'Who' is the correct relative pronoun to introduce the clause 'who lives down the street,' providing more information about Mrs. Sato. The other choices, 'she,' 'which,' and 'whom,' are not appropriate relative pronouns for referring to a person in this context.

4. Choose the sentence with correct punctuation and formatting:

• A. Throughout the song, he says “Remember the better days” and he gives examples.
• B. Throughout the song, he says, “Remember the better days,” and he gives examples.
• C. Throughout the song, he says Remember the better days, and he gives examples.
• D. Throughout the song, he says Remember the better days and he gives examples.

Correct answer: B

Rationale: The correct answer is B because it uses proper punctuation and formatting with the quotation marks around the phrase 'Remember the better days' and a comma after it to indicate the continuation of the sentence. This follows standard grammar rules for punctuating quotes within a sentence. Choice A lacks a comma after the quoted phrase, which is needed before the conjunction 'and.' Choices C and D have missing or misplaced commas and lack proper quotation marks around the quoted phrase, making them incorrect in terms of punctuation and formatting.

5. Which of the following sentences regarding thesis statements in the writing process is correct?

• A. Thesis statement wording should be as specific as possible.
• B. The written work should disprove the thesis statement.
• C. The thesis statement should appear only at the end of a paper.
• D. Supporting evidence is not needed when the thesis statement is an opinion.

Correct answer: A

Rationale: The correct answer is A. A thesis statement should be specific to provide clear direction for the paper and focus the argument. This helps guide the writing process and ensures that the paper stays on track. Choice B is incorrect because the written work should support and prove the thesis statement, not disprove it. Choice C is incorrect because the thesis statement typically appears at the beginning of a paper to introduce the main argument. Choice D is incorrect because supporting evidence is crucial in any thesis statement, regardless of whether it expresses an opinion or not.
