• Abyssal plain- The flattest part of the ocean. 50 % of the earth’s surface is being covered by this plain
• Carbohydrates They serve as a primary source of energy for living organisms and play structural roles in cells.
• Lipids Organic compounds that are insoluble in water but soluble in nonpolar solvents.
• Proteins Large, complex molecules composed of amino acid chains. Proteins serve numerous functions in organisms, including structural support, enzymatic activity, immune response, and cell signaling.
• Nucleic Acids Biomolecules that store and transmit genetic information. The two main types are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA carries the genetic instructions for the development, functioning, growth, and reproduction of organisms, while RNA plays roles in protein synthesis.
