What is the significance of the sequence of nucleotides in DNA?

• It determines the color of an organism's eyes.

• It dictates the genetic information and instructions for building proteins.

• It controls the speed of cellular processes.

• It influences the organism's lifespan.

What is the role of carbohydrates in plant structure?

• Cellulose, a carbohydrate, provides structural support in plant cell walls.

• Carbohydrates are primarily used for energy storage in plants.

• Carbohydrates are involved in photosynthesis as pigments.

• Carbohydrates help in the absorption of water in roots.

What is a disaccharide?

• A carbohydrate formed from two monosaccharides, such as sucrose.

• A type of protein made from two amino acids.

• A lipid composed of two fatty acids and a glycerol.

• A simple sugar that cannot be hydrolyzed into smaller carbohydrates.

What are the building blocks of lipids?

• Amino acids

• Glycerol and fatty acids

• Nucleotides

• Monosaccharides

What is a monosaccharide?

• A complex carbohydrate made of multiple sugar molecules.

• The simplest form of carbohydrates, consisting of a single sugar molecule, such as glucose.

• A type of lipid that stores energy in the body.

• A protein that helps in the digestion of carbohydrates.

What is the primary function of carbohydrates?

• To provide quick energy to organisms.

• To store genetic information.
