1. What is the function of the stomach in the digestive system?

• A. To absorb nutrients
• B. To break down food
• C. To produce bile
• D. To store waste

Correct answer: B

Rationale: The correct answer is B: 'To break down food.' The stomach plays a crucial role in the digestive system by breaking down food using gastric acid and digestive enzymes. This process transforms the food into a semi-liquid mixture known as chyme, which is further digested in the small intestine. Choices A, C, and D are incorrect because the stomach does not primarily absorb nutrients, produce bile, or store waste. These functions are carried out by other organs in the digestive system such as the small intestine, liver, and large intestine, respectively.

2. What is the most visible part of the ear?

• A. Ear canal
• B. Cochlea
• C. Organ of Corti
• D. Pinna

Correct answer: D

Rationale: The pinna, also known as the auricle, is the most visible part of the ear. Its external shape and location make it easily noticeable on the side of the head. The pinna helps in capturing sound waves and directing them into the ear canal, where the sound transmission process begins. The other structures listed, the Organ of Corti, Cochlea, and Ear canal, are essential parts of the ear involved in hearing and sound processing, but they are not as visibly prominent as the pinna. Therefore, the correct answer is the pinna because of its external visibility and role in capturing sound waves.

3. What organelle is responsible for packaging, processing, and shipping?

• A. Nucleus
• B. Golgi Apparatus
• C. Endoplasmic Reticulum
• D. Ribosomes

Correct answer: B

Rationale: The Golgi Apparatus is the correct answer. It is responsible for packaging, processing, and shipping proteins and lipids within the cell. The nucleus houses genetic material, the endoplasmic reticulum is involved in protein synthesis and lipid metabolism, and ribosomes are responsible for protein synthesis. Therefore, choices A, C, and D are not the correct answers for the functions of packaging, processing, and shipping.

4. Which detail is not given as a side effect of NSAIDs?

• A. Nausea
• B. Headache
• C. Weight loss
• D. Dizziness

Correct answer: C

Rationale: The passage lists several side effects of NSAIDs, including nausea, headache, and dizziness. However, weight loss is not mentioned as a side effect, making option C the correct choice since it does not align with the details provided in the text.

5. Which is true of gametes?

• A. They are diploid cells
• B. They are haploid cells
• C. They are somatic
• D. A & C are true

Correct answer: B

Rationale: Gametes are sex cells (sperm and eggs) that are involved in sexual reproduction. They are haploid cells, meaning they have half the number of chromosomes (n) compared to diploid cells. This is necessary for the formation of a diploid zygote when two gametes unite during fertilization. Somatic cells are non-reproductive cells in the body, so they are not gametes. Choice A is incorrect because gametes are not diploid but haploid. Choice C is incorrect because gametes are not somatic cells.
