1. What is the name of the microscopic finger-like projections that increase the surface area for absorption in the small intestine?

• A. Goblet cells
• B. Paneth cells
• C. Villi
• D. Crypts of Lieberkühn

Correct answer: C

Rationale: A) Goblet cells: Goblet cells are specialized cells that secrete mucus to protect the lining of the digestive tract. While important for maintaining the health of the intestines, goblet cells do not increase the surface area for absorption in the small intestine. B) Paneth cells: Paneth cells are specialized cells found in the small intestine that secrete antimicrobial peptides. They play a role in protecting the intestinal stem cells and maintaining the gut microbiota balance, but they do not increase the surface area for absorption. C) Villi: Villi are microscopic finger-like projections found in the small intestine that increase the surface area available for absorption of nutrients. Each villus contains blood vessels and lacteals (lymphatic vessels) that help absorb nutrients from digested food. D) Crypts of Lieberkühn: Crypts of Lieberkühn are small pits located between the villi

2. With which of the following statements would the author of the passage most likely agree?

• A. Malory and Tennyson shaped their approach to the Arthurian legends based on the defining qualities of their respective eras.
• B. Because Le Morte d'Arthur is more of a translation than a literary creation, Idylls of the King is a superior work.
• C. By undermining the moral qualities that Malory highlighted, Tennyson failed to appreciate the larger purpose of the stories in a medieval context.
• D. Ultimately, Malory's influence on Tennyson was minimal because Tennyson took a different approach and infused his poems with the mood of his day.

Correct answer: A

Rationale: The author of the passage would most likely agree with the statement that Malory and Tennyson shaped their approach to the Arthurian legends based on the defining qualities of their respective eras. The passage discusses how Malory emphasized the moral elements in Medieval literature, while Tennyson, as a Victorian poet, focused more on romantic qualities and nature in his works. This difference in emphasis reflects the characteristics of their eras. Therefore, choice A aligns with the author's likely agreement. Choice B is incorrect because it incorrectly compares the two works based on translation and creation, which is not the main point of comparison discussed in the passage. Choice C is incorrect because Tennyson's different approach does not necessarily mean he failed to appreciate the stories' purpose, but rather highlights a shift in emphasis. Choice D is incorrect because the passage indicates that Tennyson was indeed heavily influenced by Malory, albeit with a different approach, making Malory's influence significant rather than minimal.

3. How many chromosomes must a normal human sperm cell contain?

• A. An X chromosome.
• B. A Y chromosome.
• C. 23 chromosomes.
• D. Both an X and Y chromosome.

Correct answer: C

Rationale: A normal human sperm cell contains a total of 23 chromosomes, half the number found in a typical human cell which has 46 chromosomes. This includes 22 autosomes and one sex chromosome, which can be either an X or a Y chromosome. Therefore, the correct answer is that a normal human sperm cell must contain 23 chromosomes. Choices A and B are incorrect because a single sex chromosome alone does not represent the total number of chromosomes in a sperm cell. Choice D is incorrect because a sperm cell carries only one sex chromosome, either X or Y, not both.

4. Which of the following types of language is acceptable in a research paper?

• A. Colloquialisms
• B. Contractions
• C. Relative pronouns
• D. Second-person point of view

Correct answer: C

Rationale: Relative pronouns are acceptable in a research paper for connecting clauses. Colloquialisms (choice A) are informal expressions that are not suitable for academic writing. Contractions (choice B) are considered too casual for a research paper. The second-person point of view (choice D) should be avoided in research papers as it can make the writing less objective and scholarly.

5. Based on Gemma's preferences and limited time, which of the following travel guides will be best for her?

• A. Exploring the Hawaiian Islands: The Best Waterfalls on the Big Island and Maui
• B. Na Pali: The Two-Day Hike That Changes Everything
• C. Pineapples, Taro, and Roasted Pigs: A Dining Guide to Hawaii
• D. The Top Ten: Beaches, Restaurants, and Sightseeing in Honolulu and on Oahu

Correct answer: A

Rationale: Given Gemma's goal of seeing as much as possible in a short time while enjoying outdoor activities and nature, the best travel guide for her would be 'Exploring the Hawaiian Islands: The Best Waterfalls on the Big Island and Maui.' This guide aligns with her interest in outdoor activities and waterfalls, making it the ideal choice to enhance her trip experience. Choice B, 'Na Pali: The Two-Day Hike That Changes Everything,' focuses on a specific hike and may not cover a broad range of attractions Gemma wants to explore. Choice C, 'Pineapples, Taro, and Roasted Pigs: A Dining Guide to Hawaii,' is more food-oriented and doesn't cater to Gemma's interest in outdoor activities. Choice D, 'The Top Ten: Beaches, Restaurants, and Sightseeing in Honolulu and on Oahu,' while offering a variety of attractions, doesn't specifically target Gemma's interest in exploring waterfalls and the natural beauty of Hawaii as she desires.
