Jamillah Mitchell Professor. Jenny Harper Introductory to Biology W/Lab-Section 03G BIOL1011k Midterm StudyGuide Unit 1-Introduction to Biology: For this unit, there will be 10 randomized questions. That means that everyone can get completely different questions. However, the information you need to study is the same regardless of the question. Here are the main areas you should focus on: ●Definition of Life and the properties of Life ■All groups of living organisms share several key characteristics or functions: order, sensitivity or response to stimuli,reproduction, adaptation, growth and development, regulation, homeostasis, and energy processing. When viewed together, these eight characteristics serve to define life.●Hierarchy of Life - how is life organized (from molecular level up to biosphere) ■organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.
