1. How many chromosomes do sperm and egg produce in meiosis?

• A. 46
• B. 23
• C. 45
• D. 24

Correct answer: B

Rationale: Sperm and egg cells undergo meiosis to form gametes with half the number of chromosomes found in somatic cells. Each sperm and egg cell produces 23 chromosomes through meiosis. Choice A is incorrect because 46 chromosomes represent the diploid number found in somatic cells. Choice C is incorrect as it is an uncommon number for chromosome production in human gametes. Choice D is incorrect as the total number of chromosomes in sperm or egg cells is 23, not 24.

2. Write the date 2007 in Roman numerals.

• A. MMVII
• B. MDVII
• C. MMDII
• D. MMXD

Correct answer: A

Rationale: In Roman numerals, the date 2007 is correctly represented as MMVII. The Roman numeral M stands for 1000, and when repeated twice (MM), it represents 2000. The Roman numeral V represents 5, and when followed by II (two ones), it correctly represents 2007. Choice B (MDVII) is incorrect because D represents 500, and 2007 is greater than that. Choice C (MMDII) is incorrect because D represents 500, and there are two of them, making it 1000, not 2000. Choice D (MMXD) is incorrect as XD is an invalid Roman numeral combination.

3. Which hormone is involved in the regulation of water balance in the body?

• A. ADH
• B. Insulin
• C. Cortisol
• D. Thyroxine

Correct answer: A

Rationale: The correct answer is ADH (antidiuretic hormone), also known as vasopressin. ADH helps regulate water balance in the body by controlling the amount of water reabsorbed by the kidneys. When there is a need to conserve water, ADH levels increase, leading to more water reabsorption and concentration of urine. Insulin is involved in regulating blood sugar levels, not water balance. Cortisol is a stress hormone that helps regulate metabolism and immune response, not water balance. Thyroxine is a thyroid hormone that regulates metabolism, growth, and development, not water balance.

4. Select the word that makes the following sentence grammatically correct. It is important that one is able to self-motivate and work by ___________.

• A. oneself
• B. oneselves
• C. hisself
• D. themselves

Correct answer: A

Rationale: The word 'oneself' is a reflexive pronoun that refers back to the subject of the sentence, allowing the sentence to be grammatically correct. Options B and C, 'oneselves' and 'hisself,' are not standard English words. Option D, 'themselves,' is a plural pronoun and does not agree with the singular noun 'one' in the sentence.

5. The new manager was easy to get along with. How would you describe the new manager based on this sentence?

• A. Affable (friendly)
• B. Tortuous
• C. Apathetic
• D. Sacrosanct

Correct answer: A

Rationale: The correct choice is A - Affable (friendly). Affable means friendly and easy to get along with, which aligns with the description of the new manager in the sentence. Choice B, Tortuous, means twisting or complicated, which does not describe the manager's demeanor. Choice C, Apathetic, means showing no interest or enthusiasm, which is the opposite of the manager being easy to get along with. Choice D, Sacrosanct, means holy or sacred, which is not relevant to the context of the sentence.
