2. During which stage of meiosis II are sister chromatids separated, resulting in four genetically unique daughter cells?

• A. Prophase I
• B. Prophase II
• C. Anaphase I
• D. Anaphase II

Correct answer: D

Rationale: Rationale: - Prophase I occurs in meiosis I, not meiosis II. During Prophase I, homologous chromosomes pair up and exchange genetic material in a process called crossing over. - Prophase II is the stage where the nuclear envelope breaks down, and spindle fibers start to reappear, preparing the cell for division. Sister chromatids are still attached during Prophase II. - Anaphase I is the stage in meiosis I where homologous chromosomes are separated and pulled to opposite poles of the cell. - Anaphase II is the stage in meiosis II where sister chromatids are separated and pulled to opposite poles of the cell, resulting in four genetically unique daughter cells. This is the stage where the final separation of genetic material occurs, leading to the formation of haploid daughter cells.

3. The hormone responsible for milk production in the breasts after childbirth is:

• A. Estrogen
• B. Prolactin
• C. Oxytocin
• D. Relaxin

Correct answer: B

Rationale: The correct answer is B: Prolactin. Prolactin is the hormone responsible for milk production in the breasts after childbirth. It is produced by the pituitary gland and stimulates the alveoli in the breasts to produce milk. Estrogen plays a role in breast development during pregnancy but is not responsible for milk production. Oxytocin is responsible for the ejection of milk from the breasts during breastfeeding. Relaxin is a hormone that helps prepare the body for childbirth by relaxing the ligaments in the pelvis. Therefore, the hormone directly responsible for milk production after childbirth is prolactin.

4. What type of figurative language is used in the statement "Her laughter was music to my ears"?

• A. Metaphor
• B. Simile

5. What is the main idea of the passage?

• A. Petra is a modern city built for tourism.
• B. Petra's historical significance lies in its architectural achievements.
• C. Petra's prosperity was linked to its strategic location on trade routes.
• D. Petra's obscurity remains a mystery despite its rediscovery.

Correct answer: C

Rationale: B mentions Petra's architecture, but not its connection to trade. A and D are factually incorrect and not supported by the passage. Choice C accurately identifies Petra's rise and fall as tied to its position on the Silk Road, making it the main idea.

6. The doctor carefully examined the patient. Which word is the comparative form of the adjective "careful"?
