1. Which type of reaction typically undergoes condensation reactions?

• A. Catabolism
• B. Anabolism
• C. Exothermic
• D. Endothermic

Correct answer: B

Rationale: The correct answer is 'B: Anabolism.' Anabolic reactions typically involve condensation reactions, where smaller molecules are joined together to form larger molecules by releasing water as a byproduct. This process is fundamental in the synthesis of complex molecules such as proteins and nucleic acids. Choice A, 'Catabolism,' involves decomposition reactions where larger molecules are broken down into smaller ones, which is the opposite of condensation reactions. Choices C and D, 'Exothermic' and 'Endothermic,' refer to the heat exchange during a reaction and are not directly related to the process of condensation reactions.

2. Hampton's greatest achievement as the leader of the BPP may be his fight against street gang violence in Chicago. Which of these, if any, is misspelled?

• A. None of these is misspelled.
• B. greatest
• C. achievement
• D. leader

Correct answer: A

Rationale: All the words in the sentence are spelled correctly, including 'achievement.' There is no misspelling present. 'Greatest,' 'achievement,' and 'leader' are all spelled correctly. Option A is correct as there is no misspelled word in the sentence. Choices B, C, and D are wrong because they are correctly spelled words in the context of the sentence.

3. The SI prefixes micro and milli represent, respectively:

• A. 10^-6 and 10^-3
• B. 10^-9 and 10^-6
• C. 10^-12 and 10^-9
• D. 10^-15 and 10^-12

Correct answer: A

Rationale: The prefixes 'micro-' and 'milli-' represent 10^-6 and 10^-3, respectively. 'Micro-' denotes one-millionth (10^-6), while 'milli-' denotes one-thousandth (10^-3). Choice B is incorrect because it confuses the order of magnitudes for micro and milli. Choice C and D are also incorrect as they provide the wrong values for the prefixes micro and milli.

4. Identify the main clause in the sentence: 'Although she was tired, she finished her work on time.'

• A. Although she was tired
• B. She was tired
• C. She finished her work on time
• D. Finished her work on time

Correct answer: C

Rationale: The main clause is the independent clause that can stand alone as a complete sentence. In this sentence, 'She finished her work on time' is the main clause because it expresses a complete thought independently. Choices A and B are subordinate clauses as they cannot stand alone as complete sentences. Choice D lacks the subject 'she,' making it incomplete and not a main clause.

5. Which of the following is NOT an example of a homeostatic mechanism?

• A. Shivering when the body temperature falls.
• B. Increasing heart rate when blood pressure is low.
• C. Weight gain when consuming excess calories.
• D. Secreting insulin to decrease blood sugar concentration.

Correct answer: C

Rationale: Weight gain when consuming excess calories is not an example of a homeostatic mechanism. Homeostasis refers to the body's ability to maintain a stable internal environment despite external changes. The other options listed (A, B, and D) involve physiological responses aimed at restoring balance or stability within the body (e.g., regulating body temperature, blood pressure, and blood sugar levels). Shivering, increasing heart rate, and secreting insulin are mechanisms to counteract specific imbalances and maintain internal equilibrium. In contrast, weight gain due to excess calorie intake does not represent a specific regulatory mechanism but rather an outcome of energy imbalance. The body stores excess energy as fat rather than actively regulating a physiological parameter to restore balance.
