• Cells, tissues, organs, organ systems

• Tissues, organs, cells, organ systems

• Organ systems, cells, tissues, organs

Evolution is best described as:

• the adjustment of organisms to their environment.

• the increase in size or mass of an organism.

• a process of biological change over time.

• dthe ability of organisms to respond to stimuli.

Which of the following is CORRECT about homeostasis?

• It is a self-regulating process maintaining external stability.

• It is a process of adaptation to different environments.

• It is a process of acquiring energy from external sources.

• It is a self-regulating process maintaining internal stability.

What is the purpose of adaptation in living organisms?

• To maintain internal stability

• To increase size and mass

• To adjust to changing external conditions

• To acquire and use energy

How do living organisms acquire energy for essential functions?

• Through the process of adaptation

• From internal sources

• From external sources, such as food or sunlight

• Through the process of homeostasis

What does growth in living organisms refer to?

• Increase in size or mass

• Adjustment to the environment

• Evolutionary changes

• Reproduction of offspring

Which unifying theme in Biology emphasizes the relationship between the structure and function of an organism?

• Evolution

• Structure and Function

• Information Flow

• Energy and Matter Transformation

The Information Flow as a unifying theme in Biology involves the transfer of genetic information from:

• one organism to another.

• one generation to the next.

• the sun to producers.

• producers to consumers.

What does the theme "Energy and Matter Transformation" examine?

• How energy flows through ecosystems

• Structure and function relationships

• Evolutionary changes over time

• Interactions among living organisms

Which unifying theme in Biology encompasses ecological interactions and cellular interactions?

• Interactions

• Diversity and Unity
