  1. Biology is the study of all forms of life.

  2. biosphere = everywhere life exists Earth is home to an incredible diversity of life. The biosphere includes all living things and all the places they are found.

  3. Every part of the biosphere is connected with every other part. The biosphere includes many environments. • land environments

  4. Biodiversity is the variety of life. Biodiversity generally increases from the poles to the equator. Biodiversity is greater in areas with consistently warm temperatures. Biodiversity is greater closer to the equator.

  5. A species is one particular type of living thing. Members of a species can interbreed to reproduce. There are about 2 million different living species have been identified.

  6. All are made of one or more cells. An organism is any individual living thing.

  7. An organism is any individual living thing. • All are made of one or more cells. • All need energy for metabolism. • All respond to their environment. • All have DNA that they pass on to offspring.

  8. All levels of life have systems of related parts. A system is an organized group of interactingparts. A cell is a system of chemicals and processes. A body system includes organs that interact. An ecosystem includes living and nonliving things that interact.

  9. Structure and function are related in biology. Structure determines function. Proteinswith different structures perform different functions. Heart muscle cells have a different structure and function than stomach muscle cells. Different species have different anatomical structures with different functions.

  10. Organisms must maintain homeostasis to survive in diverse environments. Homeostasis is the maintenance of constant internal conditions.

  11. Homeostasis is the maintenance of constant internal conditions. Homeostasis is usually maintained through negative feedback. Negative feedback systems return a condition to its normal (set) point.

  12. Behaviors and adaptations can help maintain homeostasis.

  13. Evolution explains the unity and diversity of life. Evolution is the change in living things over time. The genetic makeup of a population of a species changes. Evolution can occur through natural selection of adaptations. Adaptationsare beneficial inherited traits that are passed to future generations.
