Presentation Transcript

  1. The student is expected to:4B investigate and explain cellular processes, including homeostasis, energy conversions, transport of molecules, and synthesis of new molecules; 7E analyze and evaluate the relationship of natural selection to adaptation and to the development of diversity in and among species;

  2. (Continued)10A describe the interactions that occur among systems...; 10C analyze the levels of organization in biological systems and relate the levels to each other and to the whole system; 11A describe the role of internal feedback mechanisms in the maintenance of homeostasis

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

  4. All organisms share certain characteristics. • Biology is the scientific study of all forms of life.

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

  6. 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.

  7. All levels of life have systems of related parts. • A system is an organized group of interacting parts. • 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.

  8. Biologists study many different systems.

  9. Structure and function are related in biology. • Structure determines function. • Proteins with 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. • Adaptations are beneficial inherited traits that are passed to future generations.

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