  1. KEY CONCEPTUnifying themes connect concepts from many fields of biology.

  2. All levels of life have systems of parts that interactA system is group of related parts that interact to form a whole

  3. Biologists study many different systems from the molecular to the biosphere level.

  4. All levels of life have systems of parts that interact. Cells have structures called organelles, each with their own job, which work together to keep the cell alive.

  5. All levels of life have systems of parts that interact. An Organ System is made up of individual organs that work to carry out specific jobs. Ex. Digestive

  6. All levels of life have systems of parts that interact. An Organ System is made up of individual organs that work to carry out specific jobs. Ex. Digestive The Human Organism has 11 different organ systems that Work together as one big system Can you name them all?

  7. All levels of life have systems of parts that interact. Ecosystems (ecological system) include living and nonliving things that interact to maintain Earth’s life.

  8. Structure determines function are related in biology. Protein molecules with different structures perform different functions.

  9. Structure and function are related in biology. • Cell structure determines the job it can do

  10. Structure and function are related in biology. • Cell structure determines the job it can do

  11. Structure and function are related in biology. • Structure determines function. Different species have different anatomical structures with different functions.

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

  13. 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.

  14. Behaviors and adaptations can help maintain homeostasis.

  15. 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. • Adaptations are beneficial inherited traits that are passed to future generations.

  16. Evolution accounts for both the diversity and the unity of life.

  17. Let’s Review the Unifying Themes of Biology
