Front

What determines the function of a protein molecule?

Back

The function of a protein molecule depends on its structure and how it interacts with other protein molecules.

Front

What is the term for differences in traits between individual organisms?

Back

Variation.

Front

True or False: The color of molecules determines how they function at a molecular scale, which determines the properties of the object they make up.

Back

False.

Front

What is the role of proteins in living organisms?

Back

Proteins perform a variety of functions including structural support, transport, and catalyzing biochemical reactions.

Front

What is the relationship between protein structure and function?

Back

The specific structure of a protein determines its function; changes in structure can affect its ability to perform its role.

Front

What is an example of a trait that can vary among individuals in a species?

Back

Examples include eye color, height, and leaf shape.

Front

What is the significance of variations in traits for evolution?

Back

Variations in traits can lead to natural selection, where advantageous traits become more common in a population over time.
