Final answer:
Biological macromolecules, or the building blocks of life, include proteins, carbohydrates, nucleic acids, and lipids.
Step-by-step explanation:
Understanding the Building Blocks of Life
The building blocks of life, also known as biological macromolecules, are essential large molecules necessary for existence and comprise proteins, carbohydrates, nucleic acids, and lipids.
These macromolecules are constructed from smaller organic molecules through a process called dehydration reactions, where water is removed as monomers join together.
In this context, proteins serve as the machinery of the cells, nucleic acids (like DNA and RNA) contain genetic information, carbohydrates provide energy and structural support, while lipids primarily make up the cell membrane and serve as energy storage.
To answer the question, the building blocks of life are: A) Proteins, B) Carbohydrates, C) Nucleic acids and lipids. However, since the given options do not include lipids, the most comprehensive answer we can select from them is D) All of the above.
