1. Which sentence uses the pronoun 'they' correctly?

• A. They is going to the park later today.
• B. Sarah and John said they would come to the party.
• C. The teacher said they needs to finish the report.
• D. They enjoys reading books in their free time.

Correct answer: B

Rationale: A. "They" should be used with "are," not "is." B. Correct use of "they" for multiple people (Sarah and John). C. "They" should not be paired with "needs." D. "They" should be used with "enjoy," not "enjoys."

2. Which hormones are responsible for stimulating the development of sex organs and secondary sex characteristics during puberty?

• A. Growth hormone
• B. Testosterone (in males) and Estrogen (in females)
• C. Insulin
• D. Thyroid hormone

Correct answer: B

Rationale: Testosterone and estrogen are the primary sex hormones responsible for the development of male and female sex organs, respectively, and the emergence of secondary sex characteristics during puberty. Growth hormone, insulin, and thyroid hormone do not directly influence the development of sex organs and secondary sex characteristics during puberty. Growth hormone primarily regulates growth and metabolism, insulin regulates blood sugar levels, and thyroid hormone controls metabolism and energy levels. Therefore, choices A, C, and D are incorrect for this question.

3. Which of the following is the most likely setting of the scenario below? Walking along the Thames, Julianna saw a sign advertising a fish and chips shop. Since she felt a bit peckish, she made her way over to the queue.

• A. Chicago, United States
• B. Vienna, Austria
• C. Tokyo, Japan
• D. London, England

Correct answer: D

Rationale: The mention of the Thames, fish and chips, and queue strongly indicates a British setting. Fish and chips are a traditional British dish, and the Thames is a famous river in London, England. Additionally, forming a queue is a common practice in England. Therefore, based on these cultural clues, London, England, is the most likely setting of the scenario. Choices A, B, and C are incorrect as they do not align with the specific cultural references mentioned in the scenario.

4. What is the first event to occur in a primary immune response?

• A. Macrophages phagocytose pathogens and present their antigens.
• B. Neutrophils aggregate and act as cytotoxic, nonspecific killers of pathogens.
• C. B lymphocytes make pathogen-specific antibodies.
• D. Helper T cells secrete interleukins to activate pathogen-fighting cells.

Correct answer: A

Rationale: The correct answer is A. The initial event in a primary immune response is the phagocytosis of pathogens by macrophages and the subsequent presentation of their antigens, which is crucial for initiating the adaptive immune response. Neutrophils (Choice B) are also involved in the innate immune response, but they typically respond after macrophages. B lymphocytes (Choice C) produce antibodies later in the adaptive immune response, and Helper T cells (Choice D) help in coordinating the immune response but are not the first cells to act in a primary immune response.

5. What is the cellular function of cilia and flagella?

• A. Cilia and flagella are responsible for cell movement.
• B. Cilia and flagella synthesize proteins.
• C. Cilia and flagella help protect the cell from its environment.
• D. Cilia and flagella have enzymes that help with digestion.

Correct answer: A

Rationale: The correct answer is A: Cilia and flagella are responsible for cell movement. Cilia and flagella are specialized structures found on the surface of many types of cells. They are involved in the movement of the cell itself or in moving substances around the cell. This movement helps in various functions such as propulsion, moving fluids, and sensing the environment. Choices B, C, and D are incorrect. Cilia and flagella are not involved in synthesizing proteins, protecting the cell from its environment, or aiding in digestion. Their primary function is related to cell movement and cellular transport.
