1. Which sentence avoids a dangling modifier?

• A. Walking down the street, a bird swooped down from a tree.
• B. Having finished the report, it was time for lunch.
• C. Reading the book, I learned a lot about ancient history.
• D. Exhausted from the hike, the tent was a welcome sight.

Correct answer: C

Rationale: Option C places the participle phrase "Reading the book" in front of the subject "I," eliminating the dangling modifier.

2. Which hormone is crucial for stimulating sperm production in males?

• A. Estrogen
• B. Progesterone
• C. Testosterone
• D. Insulin

Correct answer: C

Rationale: The correct answer is C: Testosterone. Testosterone is the primary male sex hormone and is crucial for stimulating sperm production in males through the process of spermatogenesis. It is produced in the testes and plays a key role in the development and maintenance of male reproductive tissues, including the testes and prostate. Estrogen and progesterone are primarily female sex hormones, while insulin regulates blood sugar levels and metabolism. Therefore, testosterone is the hormone specifically responsible for stimulating sperm production in males.

3. Deficiency of which hormone can lead to stunted growth and developmental delays in children?

• A. Estrogen
• B. Testosterone
• C. Growth hormone
• D. Insulin

Correct answer: C

Rationale: The correct answer is C: Growth hormone. Growth hormone plays a crucial role in stimulating growth, cell reproduction, and regeneration in humans. Deficiency of growth hormone can lead to stunted growth and developmental delays in children. Estrogen and testosterone are sex hormones responsible for sexual development and characteristics, but they do not directly impact growth. Insulin is a hormone that regulates blood sugar levels and is not associated with stunted growth or developmental delays.

4. A medication dosage is listed as 1/4 gram. What is the equivalent dosage in milligrams (1 gram = 1000 milligrams)?

• A. 125mg
• B. 250mg
• C. 375mg
• D. 500mg

Correct answer: D

Rationale: Multiply the gram dosage (1/4) by the conversion factor (1000mg/gram) to get 250 milligrams.

5. Which statement BEST summarizes the author's perspective on bioremediation for plastic pollution?

• A. It is the only viable solution to the problem and should be prioritized.
• B. It is a promising approach but requires further research and development.
• C. It is less effective than traditional methods and poses environmental risks.
• D. It is irrelevant to the problem and will not make a significant impact.

Correct answer: B

Rationale: The passage acknowledges the potential of bioremediation while highlighting the need for further research, indicating a balanced perspective.

6. What is the Golgi apparatus?

• A. A network of tubules that transport proteins and lipids throughout the cell
• B. A sac-like structure that stores water and nutrients
• C. The site of protein synthesis
• D. The site of protein modification and packaging

Correct answer: D

Rationale: Rationale: The Golgi apparatus is an organelle in the cell responsible for modifying, sorting, and packaging proteins and lipids for transport to their final destinations. It consists of a series of flattened sacs called cisternae and plays a crucial role in processing proteins synthesized in the endoplasmic reticulum. Option A is incorrect because the network of tubules that transport proteins and lipids throughout the cell is typically associated with the endoplasmic reticulum. Option B is incorrect as the structure described is more characteristic of a vacuole, which stores water and nutrients. Option C is incorrect as protein synthesis primarily occurs in the ribosomes, not the Golgi apparatus.
