Chapter 1 Reading and Study Guide Why This Chapter Matters 1. We are living in the golden age of biology. Biological discoveries revolutionize medicine‚ change agriculture‚ and impact human culture. 2. Life is united not by a single trait‚ but by a common set of characteristics. Appreciating what it means to be living is as complex as life itself. 3. Life exists at many levels of biological organization. Understanding how these levels interrelate provides insight into the mechanisms of living systems

easy to observe a change in colour while titrating. The solution gradually decolorized after reaching the permanganate end point due to the reaction between MnO4- and Mn2+‚ so the end point is read as quickly as possible. 2 mL of H3PO4 solution reacts with Fe3+ to produce Fe (PHO4)2- ‚

A central organizing concept in biology is that life changes and develops through evolution‚ and that all life-forms known have a common origin. The theory of evolution postulates that all organisms on the Earth‚ both living and extinct‚ have descended from a common ancestor or an ancestral gene pool. This last universal common ancestor of all organisms is believed to have appeared about 3.5 billion years ago.[21] Biologists generally regard the universality and ubiquity of the genetic code as definitive

environment. It is a movement that restores the environment that humans have damaged. Scientists have addressed the idea‚ in "A life of its own" by Michael Specter‚ of using synthetic biology to mend environmental issues. Synthetic biology combines the "elements of engineering‚ chemistry‚ computer science‚ and molecular biology…to assemble the biological tools necessary to redesign the living world" (Specter 364). There are both positive and negative impacts of a synthetic world on the environment movement
