  5. Control Group
  1. a independent variable, the component or factor being tested
  2. b Proteins organize the components within cells
  3. c the group that does not receive the experimental treatment.
  4. d entire set of genetic information that an organism carries in its DNA
  5. e 1. All modern forms of life display a common set of characteristics.
    2. Based on biological evolution.

5 Multiple choice questions

  1. Proteins facilitate the uptake and export of substances. Protein molecules that help to transport substances throughout the body and across cell membranes
  2. Experimentation that does not require a preconceived hypothesis. In some cases, the goal is to collect data to be able to formulate a hypothesis.
  3. 1. Diverse environments support diverse organisms.
  4. Matter
  5. 1. Genetic exchange between different species
    2. Relatively rare
    3. Ex: Genes that confer antibiotic resistance are sometimes transferred between different bacteria species

5 True/False questions

  1. Cell Theory1. Proposed explanation for a natural phenomenon
    2. Educated guess based on previous observations or experimental studies
    3. Hypothesis must make predictions that can shown to be correct or incorrect (must be falsifiable)
    4. Additional observations or experiments support or reject a hypothesis
    5. A hypothesis is never absolutely proven
    6. We may not have found the true explanation for a phenomenon.

          

  2. Extracellular Proteins (Proteomes)Proteins hold cells together in tissues.

          

  3. Seven Characteristics of Life1. Stores information in a stable form: The genome of every organism stores information that provides a blueprint to create its characteristics.

    2. Provides continuity from generation to generation: The genome is copied and transmitted from generation to generation.

    3. Acts as an instrument of evolutionary change: Every now and then, the genome undergoes a mutation that may alter the characteristics of an organism. In addition, a genome may acquire new genes by horizontal gene transfer. The accumulation of such changes from generation to generation produces the evolutionary changes that alter species and produce new species.

          

  4. Vertical Descent with Mutation1. Atoms
    2. Molecules and Macromolecules
    3. Cells
    4. Tissues
    5. Organs
    6. Organism
    7. Population
    8. Community
    9. Ecosystem
    10. Biosphere

          

  5. Cytoskeleton (Proteomes)Proteins are needed for cell signaling with other cells and with the environment. The molecular mechanisms by which cells detect and respond to external stimuli and send messages to other cells
