3. Unifying Themes in the Study of Life Week 2

4. Give details on how these themes serve as the foundation in the study of Biology Value life by taking good care of all beings, human, plants and animals Historical development of the concept of life Most Essential Learning Competency Describe how unifying themes (e.g., structure and function, evolution, and ecosystems) in the study of life show the connections among living things and how they interact with each other and with their environment Name the unifying themes in the study of life Describe the unifying themes illustrated Explain the connection among living things and their interaction with the environment 4 Our objectives for the week:

5. Biology is the study of life… 5

6. 6 How do you know?

7. Concepts that connect the different subdisciplines of Biology Serve as the bases of the study of Life Science Emergent properties The cell Heritable information Structure and function Interaction with the environment Regulation Unity and diversity Evolution Scientific inquiry Science, Technology and Society 7 Unifying themes

8. All levels of life have systems of related parts.  A  system  is an organized group of related parts that interact to form a whole. 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 Emergent properties

9. The smallest structure capable of all the activities of life = The Cell 9 The cell

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

13. Structure and function are related in biology     Structure and function are related in living things and relate at the level of chemicals in cells. What something does in an organism is directly related to its shape or form. Different types of cells have different functions that depend on their specialized structures. Structure and function are also related on the level of the organism. 13 Structure and function

14. Evolution accounts for both the diversity and the unity (similarities) of life. Humans and bacterial genetics are based on DNA and RNA. They both rely upon the same sources of energy with similar cell structures. Genetic diversity is responsible for the diversity of life on Earth.  Adaptation to the environment, survival of the fittest 14 Unity and diversity through Evolution

15. Organisms must maintain homeostasis to survive in diverse environments. Homeostasis  is the maintenance of constant internal conditions in an organism. Cells function best when it is within a limited range of conditions, therefore, homeostasis is important.  15 regulation

16. All organisms reproduce. It is a necessary part of living Process of making more of one’s own kind The continuity of life depends on the inheritance of biological information in the form of DNA molecules. Genetic information is encoded in the nucleotide sequences of the DNA 16 Heritable information

17. 17 Genetics

19. Observation-based discovery and the testing of explanations Depends on repeatability of observation and experiments 19 Scientific inquiry

20. It is crucial to understand the goal-oriented applications of science. 20 Science, Technology and Society

21. Biology is the study of life. There are unifying themes in Biology that connect subdisciplines to each other. The smallest structure capable of life is the cell. Organisms interact with each other and the environment. 21 Key Points

22. What is the study of life? What term means the ability of the body to maintain constant internal conditions? The smallest structure capable of all activities of life? Give two unifying themes in the study of life. 22 Knowledge check
