Study Notes
The Unity and Diversity of Life
- The unifying theme that explains the unity and diversity of life is the concept of evolution, which suggests that all living organisms share a common ancestor.
Characteristics of Organisms
- All organisms are capable of reproducing, growing, responding to stimuli, maintaining homeostasis, and carrying out metabolism.
Biological Processes
- Organisms are able to move, grow, and reproduce due to the presence of cellular structures and biological molecules, such as DNA, proteins, and ATP, which facilitate these processes.
Levels of Organization in Biology
- Biologists can study life at various levels of organization, including molecules, cells, tissues, organs, organ systems, and entire organisms.
Scientific Inquiry in Biology
- Biologists use observations, questions, and the scientific method to make sense of the natural world and understand the complexities of life.
