The document provides an overview of key concepts in biology including: - Biology is the scientific study of life through processes like observation, hypothesis formation, experimentation, and analysis of data. - The biosphere includes all living things and environments on Earth from land to oceans to the atmosphere. Biodiversity generally increases closer to the equator. - All organisms share characteristics like being made of cells, needing energy, responding to stimuli, reproducing, and adapting. Evolution explains both unity and diversity of life through natural selection of adaptations over time. - Understanding biology helps address issues like health, the environment, and new technologies like biotechnology which raises both promise and ethical questions. There are still many open questions left to
