Lecture Campbell biology: Concepts and connections (Seventh edition) - Chapter 1: Biology: Exploring life. In this chapter we will discuss: Themes in the study of biology, evolution: the core theme of biology, the process of science, biology and everyday life. | Chapter 1 Biology: Exploring Life 0 Figure Chapter 1: Big Ideas Themes in the Study of Biology The Process of Science Biology and Everyday Life Evolution, the Core Theme of Biology THEMES IN THE STUDY OF BIOLOGY © 2012 Pearson Education, Inc. All forms of life share common properties Biology is the scientific study of life. Properties of life include Order—the highly ordered structure that typifies life, Reproduction—the ability of organisms to reproduce their own kind, Growth and development—consistent growth and development controlled by inherited DNA, Energy processing—the use of chemical energy to power an organism’s activities and chemical reactions, © 2012 Pearson Education, Inc. All forms of life share common properties Response to the environment—an ability to respond to environmental stimuli, Regulation—an ability to control an organism’s internal environment within limits that sustain life, and Evolutionary adaptation—adaptations evolve over . | Chapter 1 Biology: Exploring Life 0 Figure Chapter 1: Big Ideas Themes in the Study of Biology The Process of Science Biology and Everyday Life Evolution, the Core Theme of Biology THEMES IN THE STUDY OF BIOLOGY © 2012 Pearson Education, Inc.
