Study Notes
Cells and Organisms
- Cells are the fundamental units that all organisms are made up of, highlighting the unity of life.
Unity and Diversity of Life
- The unifying theme in biology that explains the unity and diversity of life is evolution, which accounts for the common ancestry and diversity of species.
Cellular Processes
- Organisms are able to move, grow, and reproduce through the process of cellular respiration, which involves the conversion of energy and nutrients.
Scientific Method
- The scientific method used by biologists involves making observations, formulating hypotheses, and testing these hypotheses through experimentation and data analysis.
Evolution of Life on Earth
- According to scientific estimates, life on Earth is approximately 3.5-4.5 billion years old, with the earliest evidence of life dating back to at least 3.5 billion years ago.
