Study Notes
Unity and Diversity of Life
- The unifying theme in biology that explains the unity and diversity of life is evolution.
Genetic Information
- The component that processes hereditary information encoded in genes is DNA (deoxyribonucleic acid).
Scientific Method
- Biologists use the scientific method to make observations, pose questions, and form conclusions.
- The scientific method involves making observations, asking questions, forming hypotheses, and testing these hypotheses through experimentation and data analysis.
Characteristics of Life
- A defining characteristic of life on Earth is the ability to maintain homeostasis, which is the maintenance of a stable internal environment despite changes in the external environment.
- Other characteristics of life include organization, metabolism, homeostasis, growth and development, reproduction, response to stimuli, and evolution.
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.
- Each level of organization builds on the previous one, with smaller units combining to form more complex systems.
