Final answer:
The incorrect pair is C. keratin—innermost layer, containing fatty tissue, as keratin is found in the epidermis. The correct reference for the innermost layer containing fatty tissue is the subcutaneous tissue or hypodermis.
Step-by-step explanation:
The pair that is NOT correctly matched is C. keratin—innermost layer, containing fatty tissue. Keratin is actually a type of protein found in the epidermis, which is the outermost layer of the skin, not the innermost layer. Option C should refer to the subcutaneous tissue or hypodermis, which contains the fatty tissue. The hypodermis is the layer beneath the dermis that is involved in the storage of fat.
- A. epidermis—correctly identified as the thin outer membrane layer.
- B. dermis—correctly identified as the fibrous, connective tissue layer that contains various structures such as blood vessels, sweat glands, and hair follicles.
- D. melanin—correctly identified as giving skin its color, found in the epidermis.
