1. What is the purpose of the italics used for several of the works identified in the sentence above?
- A. to indicate a full-length published book
- B. to indicate a work of classic literature
- C. to indicate recommended summer reading
- D. to indicate books that Angela completed
Correct answer: A
Rationale: The purpose of the italics used for several of the works identified in the sentence above is to indicate a full-length published book. In the provided extract, titles of books such as 'The Great Gatsby,' 'Brave New World,' 'A Passage to India,' and 'The Cask of Amontillado' are italicized to emphasize them as standalone works. This formatting convention is commonly used to highlight titles of books, magazines, movies, and other individual works in written text. Choices B, C, and D are incorrect as the italics are not specifically indicating classic literature, recommended summer reading, or completion by Angela, but rather serving the general purpose of emphasizing standalone works.
2. What is the term for a group of organisms with the same genetic makeup?
- A. Population
- B. Clone
- C. Genotype
- D. Species
Correct answer: B
Rationale: In this context, a clone (option B) is a group of organisms that are genetically identical because they are derived from a single ancestor. A population (option A) refers to a group of individuals of the same species living in the same area. Genotype (option C) refers to the genetic makeup of an individual organism. Species (option D) refers to a group of organisms that can interbreed and produce fertile offspring. Therefore, the most appropriate choice for the question is 'Clone,' as it specifically refers to organisms with the same genetic makeup.
3. What is the body's primary defense against pathogens?
- A. Phagocytes
- B. Antibodies
- C. Memory B cells
- D. T lymphocytes
Correct answer: A
Rationale: The correct answer is A: Phagocytes. Phagocytes are the body's first line of defense against pathogens. They are innate immune cells that engulf and digest foreign particles like bacteria and viruses, preventing infections. Phagocytes act as the initial barrier to invading pathogens and are part of the innate immune response. Choice B, Antibodies, are produced by B cells in the adaptive immune response. Choice C, Memory B cells, are also part of the adaptive immune response and provide a faster and stronger response upon re-exposure to pathogens. Choice D, T lymphocytes, are part of the adaptive immune response, particularly involved in cell-mediated immunity.
4. The pancreas releases a number of digestive enzymes into the small intestine. Which of the following enzymes is NOT produced by the pancreas?
- A. Trypsin (protein digestion)
- B. Amylase (carbohydrate digestion)
- C. Lipase (fat digestion)
- D. Lactase (sugar digestion)
Correct answer: D
Rationale: Lactase is an enzyme responsible for breaking down lactose, a sugar found in dairy products, and it is produced by the small intestine, not the pancreas. The pancreas produces enzymes like trypsin for protein digestion, amylase for carbohydrate digestion, and lipase for fat digestion. Therefore, the correct answer is D. Choices A, B, and C are incorrect because trypsin, amylase, and lipase are indeed enzymes produced by the pancreas for the digestion of proteins, carbohydrates, and fats, respectively.
5. Most catalysts found in biological systems are which of the following?
- A. Special lipids called cofactors.
- B. Special proteins called enzymes.
- C. Special lipids called enzymes.
- D. Special proteins called cofactors.
Correct answer: B
Rationale: Enzymes are special proteins that act as catalysts in biological systems. They accelerate chemical reactions by lowering the activation energy required for the reaction to occur. Enzymes play a critical role in the regulation of metabolic pathways and are essential for various biological processes. While some enzymes may require cofactors for activity, the enzymes themselves are the catalysts in biological systems. Therefore, choice B, special proteins called enzymes, is the most suitable answer. Choices A, C, and D are incorrect because enzymes, not lipids, are the primary catalysts in biological systems.
