CHAPTER 1: INTRODUCTION: THEMES IN THE STUDY OF LIFE 9 TH I. INTRODUCTION-INQUIRING ABOUT LIFE— a. evolution –the process of change that has transformed life on Earth Examples: the ghost plant is adapted to conserving water; this helps it to survive in the crevices of rock walls b. biology – the scientific study of life I. Questions biologists may ask How does a single cell develop into an organism? How does the human mind work? How do living things interact in communities? II. What is life? No simple definition c. Properties of Life : Order (how things are structured), Regulation (Homeostasis- regulation of body temperature), Energy Processing (how organisms use food as energy), Evolutionary adaptation (survival of the fittest, camouflage), Response to the environment (stimulus), Reproduction (living things), Growth and development (genes control pattern of growth) II. THE THEMES OF THIS BOOK MAKE CONECTIONS ACROSS DIFFERENT AREAS OF BIOLOGY - Biology consists of more than memorizing factual details; themes help to organize biological information a. THEME: New Properties Emerge at Each Level in the Biological Hierarchy- Life can be studied at different levels, from molecules to the entire living planet; the study of life can be divided into different levels of biological organization 1. Emergent properties result from the arrangement and interaction of parts as complexity increases within a system I. Examples: i. In organisms Photosynthesis cannot be replicated in a lab because there is a specific organization of chlorophyll and chloroplast molecules in a chloroplast. A hit in the head can cause the mind to not function correctly because the hit disrupted the complex functioning of the brain. ii. In Nonliving things a functioning bicycle emerges only when all of the necessary parts connect in the correct way pencil lead and diamonds are made out of pure carbon, but have different appearances and properties due to the structure of the carbon atoms 2. The power and limitations of reductionism I. Definition of reductionism : the approach of reducing complex systems to simpler components that are more manageable to study II. Benefits: Studying the molecular structure of DNA could serve as a chemical basis of inheritance III. Drawbacks: DNA was better understood when scientists were able to study the interactions of DNA with other molecules 3. Systems biology –an approach that attempts to model the dynamic behavior of whole biological systems based on a study of the interactions among the system’s part I. System - a combination of components that function together II. Goal-To answer large scale questions about how the parts of the cells, organisms, and higher levels of order work together III. Sample Questions- How does a drug for blood pressure affect other organs?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
