What are the monomers of carbohydrates?

Back

Monosaccharides are the monomers of carbohydrates, serving as the simplest form of sugars.

Front

What are lipids and their primary function?

Back

Lipids are organic molecules that include fats and oils, primarily serving as long-term energy storage and structural components of cell membranes.

Front

What is the significance of genetic variation in a population?

Back

Genetic variation is crucial for the survival of a species, as it allows populations to adapt to changing environments and resist diseases.

Front

What is the process of cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.
