Final answer:
Triglycerides are the monomers that allow for the hibernation process in animals as they serve as long-term energy storage, which is vital during the periods when animals are not actively feeding.
Step-by-step explanation:
Many animals hibernate during the winter. The building blocks that allow for this process to happen are triglycerides. This is because triglycerides serve as a long-term energy storage in animals and can be broken down to provide energy during periods when the animal is not actively feeding, like hibernation. While amino acids are the monomers of proteins, nucleotides are the monomers of nucleic acids, and monosaccharides are the basic units of carbohydrates, triglycerides, which are lipids, are the most relevant monomers for this process. Lipids provide the densest energy storage, and animals rely on the metabolic conversion of stored fats to survive long durations without food.
Other monomers mentioned serve different functions in the body. Amino acids are used mainly for protein synthesis and repair and, though they can be metabolized for energy, are not the primary energy reserve. Similarly, monosaccharides are a quick source of energy but are not generally stored in significant amounts for processes like hibernation. Nucleotides, on the other hand, are not used for energy storage at all but are the building blocks for the synthesis of nucleic acids that store and transmit genetic information.
