Question

multiple choice question
the layer of triglycerides beneath the skin serves to

insulate the body.

emulsify lipids during digestion.

synthesize hormones, such as estrogen and testosterone.

transport fat - soluble vitamins through the blood.

Explanation:

• The subcutaneous triglyceride (fat) layer acts as a thermal barrier, reducing heat loss from the body.
• Emulsifying lipids is the role of bile salts in the digestive tract, not subcutaneous fat.
• Hormone synthesis like estrogen/testosterone from lipids occurs in endocrine glands, not the skin's fat layer.
• Transporting fat-soluble vitamins is done by lipoproteins in the bloodstream, not subcutaneous triglycerides.

Answer:

insulate the body.
