Study Notes
Unifying Themes in Biology
- The primary unifying theme in the field of biology is the study of life and its processes
Characteristics of Organisms
- Organisms are able to move, grow, and reproduce due to the presence of cells and the ability to respond to stimuli, grow and develop, reproduce, respond to the environment, metabolize, and maintain homeostasis
Levels of Organization
- Biologists study life at multiple levels of organization, including molecules, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystems, and the biosphere
Scientific Tools and Methods
- The primary tool used by biologists to make observations and form conclusions is the scientific method, which involves making observations, forming hypotheses, and testing these hypotheses through experimentation and data analysis
Origin of Life on Earth
- Life on Earth is believed to have emerged around 3.5 billion years ago
