  1. a Organisms capture, use, and store energy in biological processes such as growth, reproduction and maintaining homeostatic processes.
  2. b Biological systems possess multiple mechanisms that increase genetic variation.
  3. c Interactions between external stimuli and gene expression result in specialization of cells, tissues, and organs.
  4. d DNA, and in some cases RNA, is the primary source of heritable information.
  5. e The subcomponents of a biological polymer and their sequence determine the properties of that polymer.

5 Multiple choice questions

  1. Organisms exchange information with each other in response to internal changes and external cues, which may change behavior.
  2. Growth and dynamic homeostasis is maintained by the constant movement of molecules across membranes.
  3. Cells communicate with each other through direct contact with other cells or from a distance via chemical signaling.
  4. Changes in genotype can result in changes in phenotype.
  5. Errors in normal signal transduction may alter cellular response.

5 True/False questions

  1. 3.A.3Mendelian genetics provides a basic understanding of the underlying causes of the pattern traits from parent to offspring.


  2. 3.D.3.Signal transduction pathways link signal reception with cellular response.


  3. 3.B.2A variety of intercellular and intracellular signal transmissions mediate gene expression.


  4. 3.D.1Cell communication involves processes resulting from evolution that are shared common features.


  5. 2.E.2.Organisms use negative feedback mechanisms to maintain their internal environments and respond to external environmental changes.
