Triglycerides' Additional Functions

Steps:

• Identify triglycerides as lipids used for energy storage, insulation, and cushioning.
• Evaluate statement 1: triglycerides provide thermal insulation in animals.
• Evaluate statement 2: triglycerides do not act as hormones; that's steroids.
• Evaluate statement 3: triglycerides cushion organs against mechanical shock.
• Select option matching correct statements 1 and 3.

Why C is correct:

• Triglycerides function in insulation (adipose tissue) and protection (padding organs), per lipid biology definitions.

Why the others are wrong:

• A includes incorrect statement 2 on hormonal function.
• B omits correct statement 3 on cushioning.
• D omits correct statement 1 on insulation.

Not enough information on exact statements, but based on standard biology.

Final answer: C
