The unifying themes in biology include the cellular basis of life, heredity and evolution, and the relationship between structure and function.

What is the role of biologists in using the scientific method?

Like other scientists, biologists use the scientific method to make observations, pose questions, and test hypotheses.

How does energy processing relate to the importance of life?

Energy processing is important to life as it allows organisms to move, grow, and reproduce.

What are the levels of organization at which biologists can study life?

<p>Biologists can study life at multiple levels of organization, from the molecular biology of a cell to the anatomy and physiology of plants and animals, and evolution of populations.</p> Signup and view all the answers

Explain the significance of the unity and diversity of life in biology.
