**1.** Read the passage and answer the question.
*The skin is the largest organ of the human body. It serves multiple functions, including protection
against pathogens, regulation of body temperature, and synthesis of vitamin D. The outermost layer, the
epidermis, contains melanocytes that produce melanin, the pigment responsible for skin color. The
dermis, beneath the epidermis, contains blood vessels, nerve endings, and hair follicles.*
Which layer of the skin contains melanocytes?
A) Dermis
B) Subcutaneous tissue
C) Epidermis
D) Hypodermis
**Answer:** C
**Rationale:** The passage explicitly states: "The outermost layer, the epidermis, contains melanocytes
that produce melanin." Therefore, melanocytes are located in the epidermis, not the dermis or deeper
layers.
**2.** Based on the passage above, which of the following is a function of the skin?
A) Producing red blood cells
B) Storing calcium
C) Regulating body temperature
D) Digesting food
, **Answer:** C
**Rationale:** The passage lists three functions: protection, temperature regulation, and vitamin D
synthesis. Regulating body temperature is clearly stated. Red blood cell production occurs in bone
marrow, calcium storage in bones, and digestion in the digestive system.
**3.** The word "synthesis" in the passage most nearly means:
A) Breakdown
B) Absorption
C) Production
D) Elimination
**Answer:** C
**Rationale:** In context, "synthesis of vitamin D" refers to the skin producing or making vitamin D
when exposed to sunlight. Synthesis means the combination of components to form a new substance.
