1. What figure of speech is used in the statement "His words were a dagger to my heart"?

• A. Metonymy
• B. Simile
• C. Metaphor (Correct)
• D. Hyperbole

Correct answer: C

Rationale: The statement compares the pain of his words to a physical object, forming a metaphor.

2. Which phenomenon describes the separation of light into its component colors when passing through a prism?

• A. Refraction
• B. Diffraction
• C. Dispersion
• D. Reflection

Correct answer: c

Rationale: Dispersion occurs when light passes through a prism, causing different wavelengths (colors) to separate due to their varying speeds through the medium.

3. After exposure to a pathogen, the immune system develops memory. What type of immune cell is responsible for this immunological memory?

• A. B cells
• B. T cells (specifically memory T cells)
• C. Phagocytes
• D. Natural killer cells

Correct answer: B

Rationale: The correct answer is A: "B cells." B cells are responsible for generating immunological memory after exposure to a pathogen. When B cells encounter a pathogen, they differentiate into memory B cells, which can quickly recognize and respond to the pathogen upon subsequent exposure. These memory B cells are crucial for mounting a faster and more effective immune response, leading to a quicker clearance of the pathogen. T cells, phagocytes, and natural killer cells play important roles in the immune response, but specifically, memory B cells are responsible for immunological memory.

4. Which element is used in fluorescent lamps and emits ultraviolet light when excited?

• A. Mercury
• B. Neon
• C. Argon
• D. Krypton

Correct answer: A

Rationale: Mercury vapor in fluorescent lamps generates UV light that excites phosphors on the lamp's inner surface, producing visible light.

5. What is the involuntary muscle tissue found in the walls of blood vessels and organs like the stomach and intestines?

• A. Skeletal muscle
• B. Cardiac muscle
• C. Smooth muscle
• D. Striated muscle

Correct answer: C

Rationale: The correct answer is C: Smooth muscle. Smooth muscle is the involuntary muscle tissue that is found in the walls of blood vessels and organs like the stomach and intestines. Unlike skeletal muscle, which is voluntary and under conscious control, smooth muscle functions involuntarily, allowing organs to contract and relax without conscious effort. Cardiac muscle, while also involuntary, is specifically found in the heart. Striated muscle refers to both skeletal and cardiac muscle, which exhibit a striped appearance under a microscope due to the arrangement of their filaments. Therefore, smooth muscle is the most appropriate answer for this question.

6. Which sexually transmitted infection (STI) can potentially cause infertility in both men and women if left untreated?

• A. Human papillomavirus (HPV)
• B. Chlamydia
• C. Gonorrhea
• D. Syphilis

Correct answer: D

Rationale: The correct answer is D: Syphilis. Syphilis is a sexually transmitted infection that can potentially cause infertility in both men and women if left untreated. In men, untreated syphilis can lead to damage to the testicles and epididymis, affecting sperm production. In women, syphilis can result in pelvic inflammatory disease (PID) which can lead to scarring and blockages in the fallopian tubes, causing infertility. While other STIs like chlamydia and gonorrhea can also lead to infertility if left untreated, syphilis is particularly known for its severe impact on reproductive health in both genders.
