  1. a Cell communication involves processes resulting from evolution that are shared common features.
  2. b Organisms use negative feedback mechanisms to maintain their internal environments and respond to external environmental changes.
  3. c Timing and coordination of several events are necessary for the normal development of an organism, and these events require regulation by multiple mechanisms.
  4. d Variation in molecular units provides cells with a wider range of functions.
  5. e DNA, and in some cases RNA, is the primary source of heritable information.

5 Multiple choice questions

  1. Organisms exchange information with each other in response to internal changes and external cues, which may change behavior.
  2. Errors in normal signal transduction may alter cellular response.
  3. Eukaryotic cells maintain internal membranes that partition the cell into specialized regions.
  4. Changes in genotype can result in changes in phenotype.
  5. Positive feedback mechanisms amplify responses and processes in biological organisms.

5 True/False questions

  1. 4.A.4.Organisms exhibit complex properties due to interactions between their constituent parts.

          

  2. 4.C.2.Environmental factors influence the expression of the genotype in an organism.

          

  3. 4.A.2.Interactions of subcellular structures, including a repertory of eukaryotic organelles possessing specialized functions, provide essential cellular functions and activities.
