Biology Basics

Biology as a Scientific Study

• Biology is the scientific study of life, encompassing a broad scope of topics.
• It is a natural science with unifying themes that tie it together as a single, coherent field.

Unifying Themes in Biology

• All organisms are composed of cells that process hereditary information encoded in genes, which can be transmitted to future generations.
• Evolution explains the unity and diversity of life.
• Energy processing is essential to life, enabling organisms to move, grow, and reproduce.
• Organisms are capable of regulating their own internal environments.

Levels of Organization in Biology

• Biologists study life at multiple levels, from the molecular biology of a cell to the anatomy and physiology of plants and animals.
• The evolution of populations is also a key area of study.

Subdisciplines in Biology

• Multiple subdisciplines exist within biology, each defined by the nature of their research questions and the tools they use.

The Scientific Method in Biology

• Biologists employ the scientific method to make observations, pose questions, and develop hypotheses.
