1. Which of the following organelles is responsible for food and water storage in the cell?

• A. Centriole
• B. Lysosome
• C. Ribosome
• D. Vacuole

Correct answer: D

Rationale: The correct answer is D, Vacuole. Vacuoles are membrane-bound organelles responsible for the storage of various substances such as food, water, and waste in a cell. They help maintain the cell's turgidity and regulate the movement of substances within the cell. Choice A, Centriole, is involved in cell division and organization of microtubules but not food and water storage. Choice B, Lysosome, contains digestive enzymes for breaking down cellular waste material and foreign invaders. Choice C, Ribosome, is involved in protein synthesis rather than storage of food and water.

2. A student wants to rewrite the following sentence: Entrepreneurs use their ideas to make money. He wants to use the word money as a verb, but he isn’t sure which word ending to use. What is the appropriate suffix to add to money to complete the following sentence? Entrepreneurs __________ their ideas.

• A. –ize
• B. –ical
• C. –en
• D. –ful

Correct answer: A

Rationale: The correct answer is A: '-ize'. When '–ize' is added to 'money', it forms the word 'monetize'. 'Monetize' means to turn something into money or profit. Therefore, the sentence should read: 'Entrepreneurs monetize their ideas,' which accurately conveys the intended meaning of using ideas to generate profit. Choice B, '–ical', is incorrect as it does not create a verb from 'money'. Choices C and D, '–en' and '–ful', are also incorrect as they do not form a verb related to 'money' in the context of the sentence.

3. Which word choices will correctly complete the sentence? Increasing the price of bus fares has had a greater effect on ridership than expected.

• A. affect; then
• B. affect; than
• C. effect; then
• D. effect; than

Correct answer: D

Rationale: In this sentence, 'effect' is the correct word as it refers to the result of increasing bus fares. Additionally, 'than' is used for making comparisons, which is appropriate in this context. 'Affect' is incorrect as it is a verb, not a noun, and 'then' is incorrect as it should be 'than' to show the comparison between the actual outcome and the expected outcome.

4. What macromolecules are formed from amino acids, and what are their roles?

• A. Lipids; store energy
• B. Carbohydrates; provide energy
• C. Proteins; perform various functions like catalysis, transport, and structural support
• D. Nucleic acids; store genetic information

Correct answer: C

Rationale: The correct answer is C. Proteins are macromolecules formed from amino acids and have diverse roles, such as serving as enzymes, transport molecules, and providing structural support. They are essential for catalysis, cellular communication, immune response, and many other functions in living organisms. Choices A, B, and D are incorrect. Lipids are not formed from amino acids but from fatty acids and glycerol, mainly serving as energy storage molecules. Carbohydrates are composed of sugars and provide energy to the body. Nucleic acids, like DNA and RNA, are made up of nucleotides and store genetic information in cells.

5. To which section of the library should Jorgen go to find out more about the current applications of the sieve of Eratosthenes?

• A. 000
• B. 100
• C. 400
• D. 500

Correct answer: D

Rationale: Jorgen should go to the 500 section of the library, which covers science and mathematics, to find out more about the current applications of the sieve of Eratosthenes. The sieve of Eratosthenes is a mathematical tool used to determine prime numbers, making the science and mathematics section the most appropriate choice. Philosophy and psychology (100), languages (400), and computer science (000) are not the primary areas where one would typically find information on the applications of this mathematical tool.
