1. In a study where fish are fed different amounts of food daily for four weeks in separate tanks, with fish weight measured weekly, what is the dependent variable?

• A. Weight of the fish
• B. Type of food used
• C. Number of fish tanks
• D. Frequency of feedings

Correct answer: A

Rationale: The weight of the fish is the dependent variable in this study because it is the outcome being measured in response to the varying feeding amounts. The weight of the fish changes based on the feeding regimen, making it the dependent variable. The type of food used (choice B), number of fish tanks (choice C), and frequency of feedings (choice D) are not the dependent variables in this study. These factors may be independent variables that are manipulated or controlled in the experiment to observe their impact on the dependent variable, which is the weight of the fish.

2. Which hormone is responsible for lowering blood sugar levels?

• A. Glucagon
• B. Insulin
• C. Adrenaline
• D. Cortisol

Correct answer: B

Rationale: Insulin is the hormone responsible for lowering blood sugar levels. It is produced by the pancreas and facilitates the entry of glucose into cells, thereby reducing blood sugar levels. Glucagon, adrenaline, and cortisol have roles in increasing blood sugar levels through various mechanisms. Glucagon raises blood sugar levels by stimulating the liver to release stored glucose, adrenaline increases blood sugar in fight-or-flight responses, and cortisol raises blood sugar levels as part of the stress response. Therefore, in the context of lowering blood sugar levels, insulin is the correct answer.

3. Caret, carrot, and to, two, and too share something in common. They:

• A. Are nouns
• B. Are monosyllabic
• C. Are homophones
• D. Represent things in nature

Correct answer: C

Rationale: The correct answer is C. Caret, carrot, and to, two, and too are all examples of homophones. Homophones are words that sound alike but have different meanings and spellings. In this case, while these words are spelled differently and have different meanings, they are pronounced the same way. Choices A, B, and D are incorrect because these words being discussed do not all fall under the same grammatical category as nouns, monosyllabic words, or representations of things in nature. The commonality among these words lies in being homophones, not in being nouns, monosyllabic, or representations of nature.

4. Which type of reaction builds larger and more complex molecules from smaller ones, requiring energy?

• A. Catabolic reaction
• B. Anabolic reaction
• C. Exothermic reaction
• D. Hydrolytic reaction

Correct answer: B

Rationale: The correct answer is 'Anabolic reaction.' Anabolic reactions involve the synthesis of larger and more complex molecules from smaller ones, requiring an input of energy, often in the form of ATP. These reactions are essential for processes like growth, repair, and the building of cellular structures. Catabolic reactions, on the other hand, break down larger molecules into smaller ones, releasing energy. Exothermic reactions release heat, while hydrolytic reactions involve the breakdown of molecules with the addition of water. Therefore, choices A, C, and D are incorrect as they do not describe the process of building larger and more complex molecules from smaller ones with the requirement of energy.

5. Which of the following statements represents an EXAGGERATED claim in support of the argument presented in the passage?

• A. In the United States, the foreign language requirement for high school graduation is decided at the state level.
• B. Studying a foreign language has become increasingly important for the global economy.
• C. High school graduates with foreign language credits have been shown to have an increased college acceptance rate.
• D. Students who did not study a foreign language often find themselves unable to obtain a job at all.

Correct answer: D

Rationale: While it is true that studying a foreign language can enhance one's job prospects and competitiveness in the job market, claiming that students who did not study a foreign language often find themselves unable to obtain a job at all is an exaggerated statement. Many factors contribute to employability, and while language skills can be advantageous, they are not the sole determining factor in securing employment.
