1. What is the structure and function of elastic arteries?

• A. They are the smallest arteries and constrict and dilate frequently.
• B. They are medium-sized arteries that distribute blood to various organs.
• C. They are the largest arteries and stretch and recoil to accommodate blood pressure changes.
• D. They are thin-walled arteries that supply blood to the capillaries.

Correct answer: C

Rationale: The corrected answer is C. Elastic arteries, like the aorta, are the largest arteries in the body. They possess elastic fibers in their walls, allowing them to stretch and recoil in response to the pulsatile nature of blood flow from the heart. This elasticity helps to maintain blood pressure by absorbing the pressure waves generated by the heart's contractions and ensuring continuous blood flow to the organs. Choices A, B, and D are incorrect because elastic arteries are not the smallest arteries, do not constrict and dilate frequently, are not medium-sized arteries for distributing blood to various organs, and are not thin-walled arteries supplying blood to capillaries. Elastic arteries have a specific structure and function related to their ability to accommodate blood pressure changes due to their elastic properties, which is essential for the cardiovascular system's proper functioning.

2. While researching Chomsky's many theories and arguments, Teddy became interested in post-World War II anarchism. Which section of the library is the most likely to contain the relevant books?

• A. 000
• B. 200
• C. 300
• D. 900

Correct answer: C

Rationale: Since anarchism is a social science theory, it falls under the classification of social sciences in the Dewey Decimal System. Section 300 covers social sciences, making it the most suitable section for finding books related to post-World War II anarchism. Choice A (000 - Computer science), Choice B (200 - Religion), and Choice D (900 - History) are incorrect because they do not directly relate to social sciences where anarchism would be classified.

3. Which of the following sentences contains a colloquialism?

• A. The Centers for Disease Control and Prevention is pretty sure that the Zika virus is spread through mosquito bites.
• B. Travelers who are pregnant or considering pregnancy should consult a doctor.
• C. Some theories on the Zika virus are difficult to understand.
• D. In response, the U.S. has taken steps to prevent the spread of the Zika virus.

Correct answer: A

Rationale: The correct answer is A because the phrase 'pretty sure' is a colloquialism, making the sentence less formal. Choice B is incorrect as it is a formal recommendation. Choice C is incorrect as it contains no colloquial expressions. Choice D is incorrect as it is a straightforward statement without colloquial language.

4. Which organelle is responsible for controlling the activities of the cell?

• A. Golgi apparatus
• B. Mitochondria
• C. Nucleus
• D. Ribosomes

Correct answer: C

Rationale: The nucleus is the organelle responsible for controlling the activities of the cell. It contains the cell's genetic material (DNA) and serves as the command center of the cell, regulating gene expression and directing cellular activities. The nucleus plays a crucial role in cell growth, metabolism, and reproduction. While the Golgi apparatus is involved in processing and packaging proteins, the mitochondria are responsible for producing energy in the form of ATP, and ribosomes are involved in protein synthesis, none of these organelles have the primary function of controlling the activities of the cell like the nucleus does. Therefore, the correct answer is the nucleus.

5. Which of the following statements about prions is TRUE?

• A. They are composed of proteins only
• B. They are easily destroyed by common disinfectants
• C. hey are a type of antibiotic
• D. They are a live organism

Correct answer: A

Rationale: A) This statement is true. Prions are infectious agents composed entirely of protein, lacking nucleic acids such as DNA or RNA. They are known for causing neurodegenerative diseases in animals and humans. B) This statement is false. Prions are not easily destroyed by common disinfectants due to their unique structure and resistance to conventional sterilization methods. C) This statement is false. Prions are not a type of antibiotic. They are a distinct class of infectious agents. D) This statement is false. Prions are not live organisms but rather misfolded proteins that can induce abnormal folding in normal proteins, leading to disease.
