Solution
The correct option is D Content
of unsaturated fatty acids
Fats contain twice as much energy as carbohydrates. Layers of fat also surround the vital organs of animals to cushion them, and layers of fat under the skin of animals provide insulation. Many organisms (fish are one example) are capable of adapting to cold environments by changing the proportion of unsaturated fatty acids in their membranes in response to the lowering of the temperature.
