Subcutaneous tissue

• A. Forms the middle layer of the skin
• B. Forms the outermost layer of the skin
• C. Keeps the temperature of the body normal range
• D. Provides extra fuel for the body

Answer: (D)

Subcutaneous tissue stores fat that serves as an energy reserve, providing extra fuel for the body when needed. This adipose-rich layer lies beneath the dermis and cushions and insulates the body, but its defining role is energy storage. The other statements describe the wrong skin layer (the middle layer is the dermis; the outer layer is the epidermis) or a broad, systemic function not specific to this tissue.
