Study Notes
The Unifying Theme of Life
- The unifying theme that explains the unity and diversity of life is evolution, which suggests that all living organisms share a common ancestry.
The Fundamental Unit of Life
- The fundamental unit that all organisms are made up of is the cell, which is the basic structural and functional unit of life.
Characteristics of Life
- Organisms are able to move, grow, and reproduce due to the basic characteristics of life, which include organization, metabolism, homeostasis, response to stimuli, growth and development, reproduction, and evolution.
Levels of Organization
- Biologists study life at various levels of organization, including the molecular, cellular, tissue, organ, organ system, and organism levels.
The Scientific Process
- Biologists use observations, questions, and hypotheses to make discoveries and advance our understanding of life, and they use the scientific method to test their hypotheses and develop theories.
