1. A.J. wrote an essay about the Civil War, making sure to include the vital information of who, what, where, when, and why. His teacher commended him on his thorough research.

• A. Emphasis paragraph
• B. Supporting details
• C. Topic sentence
• D. Transitions

Correct answer: B

Rationale: The correct answer is B: Supporting details. Supporting details are specific information that backs up the main points in an essay, such as the who, what, where, when, and why in A.J.'s essay about the Civil War. In this case, A.J. included crucial facts and explanations to support his main arguments. Choice A, 'Emphasis paragraph,' does not directly relate to providing specific information like supporting details do. Choice C, 'Topic sentence,' introduces the main idea of a paragraph, not the specific supporting information. Choice D, 'Transitions,' are used to connect ideas and paragraphs smoothly, but they do not provide the specific information needed to support the main points in an essay.

2. Blood type is a trait determined by multiple alleles, with IA and IB being co-dominant: IA codes for A blood and IB codes for B blood, while i codes for O blood and is recessive to both. If an A heterozygote individual and an O individual have a child, what is the probability that the child will have A blood?

• A. 25%
• B. 50%
• C. 75%
• D. 100%

Correct answer: B

Rationale: If an A heterozygote (IAi) and an O individual (ii) have a child, there is a 50% chance the child will inherit the IA allele and have A blood. The A heterozygote can pass on either the IA or i allele, while the O individual can only pass on the i allele. Therefore, the possible genotypes for the child are IAi (A blood) or ii (O blood), resulting in a 50% chance of the child having A blood. Choice A (25%) is incorrect as it does not take into account the possibility of inheriting the IA allele. Choice C (75%) and Choice D (100%) are incorrect as they overestimate the probability of the child having A blood.

3. How many ounces is equal to 1 gram?

• A. 0.015 ounces
• B. 0.035 ounces
• C. 0.045 ounces
• D. 0.055 ounces

Correct answer: B

Rationale: To convert grams to ounces, you need to multiply the weight in grams by 0.035 to get the equivalent weight in ounces. Therefore, 1 gram is equal to 0.035 ounces. Choices A, C, and D are incorrect conversions and do not accurately represent the conversion factor from grams to ounces.

4. During which phase of meiosis do chiasmata structures form?

• A. Prophase I
• B. Prophase II
• C. Metaphase I
• D. Metaphase II

Correct answer: A

Rationale: Chiasmata structures, where crossing over occurs, form during Prophase I of meiosis. This phase is characterized by homologous chromosomes pairing up and crossing over, leading to the exchange of genetic material between non-sister chromatids. Chiasmata are visible points of contact where genetic material has been exchanged, and they play a critical role in genetic diversity. Prophase II is the phase where chromosomes condense again in the second meiotic division, but chiasmata formation occurs in Prophase I. Metaphase I is the phase where homologous chromosomes align at the metaphase plate, not where chiasmata form. Metaphase II is the phase where replicated chromosomes align at the metaphase plate in the second meiotic division, but chiasmata formation occurs earlier in Prophase I.

5. What is the main argument presented in the passage?

• A. The custom of tipping should be abolished in favor of paying servers a living wage
• B. Tipping enhances service quality in restaurants
• C. Servers' pay should be determined by their performance
• D. Customers derive pleasure from the custom of tipping

Correct answer: A

Rationale: The correct answer is A: 'The custom of tipping should be abolished in favor of paying servers a living wage.' The rationale is that the passage argues for eliminating tipping and ensuring servers receive a fair wage. This is supported by the idea that servers should be paid adequately rather than relying on tips. Choice B is incorrect because the passage does not support the idea that tipping enhances service quality; it argues for a living wage instead. Choice C is incorrect as there is no mention of paying servers based on performance in the passage. Choice D is incorrect as the passage does not focus on customers' enjoyment of tipping but rather on the need to abolish the practice for fairer wages.
