1. How many chromosomes must a normal human sperm cell contain?

• A. An X chromosome.
• B. A Y chromosome.
• C. 23 chromosomes.
• D. Both an X and Y chromosome.

Correct answer: C

Rationale: A normal human sperm cell contains a total of 23 chromosomes, half the number found in a typical human cell which has 46 chromosomes. This includes 22 autosomes and one sex chromosome, which can be either an X or a Y chromosome. Therefore, the correct answer is that a normal human sperm cell must contain 23 chromosomes. Choices A and B are incorrect because a single sex chromosome alone does not represent the total number of chromosomes in a sperm cell. Choice D is incorrect because a sperm cell carries only one sex chromosome, either X or Y, not both.

2. Which of the following choices contains an error in verb tense?

• A. She said that she would finish the report yesterday.
• B. We went to the store last week.
• C. They had seen the movie before it was released.
• D. The dogs will play outside when we arrive.

Correct answer: A

Rationale: The correct answer is choice A, 'She said that she would finish the report yesterday.' This sentence contains a verb tense error. The reported speech 'She said' requires the verb 'would' to maintain the past tense. Choices B and D are correct as they use the appropriate verb tenses 'went' and 'will play.' Choice C is also correct as it uses 'was released' to match the past perfect tense 'had seen.'

3. Which word completes the sentence: 'Despite the storm, the concert ____ went on.'

• A. nevertheless
• B. however
• C. therefore
• D. nonetheless

Correct answer: D

Rationale: 'Nonetheless' is the correct word to complete the sentence as it emphasizes the continuation of the concert despite the contrary circumstance. 'Nevertheless' and 'however' are synonyms and indicate contrast rather than continuity. 'Therefore' implies a conclusion or result, which is not fitting in this context.

4. How many liters are in 3,000 milliliters?

• A. 0.3 liters
• B. 30 liters
• C. 3 liters
• D. 0.03 liters

Correct answer: C

Rationale: To convert milliliters to liters, you need to divide by 1,000 since there are 1,000 milliliters in a liter. Therefore, 3,000 milliliters / 1,000 = 3 liters. Choice A '0.3 liters' is incorrect as it represents 300 milliliters, not 3,000. Choice B '30 liters' is incorrect as it is the result of multiplying by 10 instead of dividing by 1,000. Choice D '0.03 liters' is incorrect as it represents 30 milliliters, not 3,000.

5. Which of the following organs functions as both an endocrine and exocrine gland?

• A. The kidney
• B. The spleen
• C. The pancreas
• D. The stomach

Correct answer: C

Rationale: The pancreas is the correct answer as it functions as both an endocrine and exocrine gland. The endocrine function involves secreting insulin and glucagon into the bloodstream to regulate blood sugar levels, while the exocrine function involves releasing digestive enzymes into the small intestine to aid in digestion. The kidney (Choice A) primarily functions in the excretory system by filtering blood and producing urine. The spleen (Choice B) is involved in the immune system and blood storage but does not have endocrine or exocrine functions. The stomach (Choice D) is mainly an organ of the digestive system, secreting gastric juices to aid in digestion, but it does not have a dual endocrine and exocrine function like the pancreas.
