  STANDARDS:
    maximum of 6 points for each section
  
  PHEROMONES - 6 points maximum
  DESCRIPTION/DEFINITION:
     general description/definition
     of a releaser
     of a primer                                  
                                             (max 3)
  DEMONSTRATES UNDERSTANDING BY CORRECT EXPLANATION OF AN EXAMPLE:
     explanation 
     example 
     releaser example/explanation (ants, urine) 
     primer example/explanation (locusts, mice, queen bee)       
                                             (max 4)
  SELECTIVE ADVANTAGE:
     courtship behavior
     sexual receptivity 
     reduce competition / "tidiness" among ants - death pheromone
     increase food gathering
                                             (max 4)
                                             Total = 11 (max 6)
  MIMICRY - 6 points maximum
  DESCRIPTION/DEFINITION:
     general description/definition
     of Batesian mimicry
     of Mullerian mimicry                              
                                             (max 3)
  DEMONSTRATES UNDERSTANDING BY CORRECT EXPLANATION OF AN EXAMPLE:
     explanation 
     example 
     Batesian example/explanation 
     Mullerian example/explanation                                                                            (max 4) 

  SELECTIVE ADVANTAGE:
     survival/escapes predation 
     pollination 
     protection
     selection pressure                           
                                             (max 4)
                                        Total = 11 (max 6)

  INSTINCT - 6 points maximum
  DESCRIPTION/DEFINITION:
     general description/definition 
     of releaser/sign stimuli
     of IRM 
                                             (max 3)
  DEMONSTRATES UNDERSTANDING BY CORRECT EXPLANATION OF AN EXAMPLE:
     explanation 
     example 
     releaser explanation/example (chaffinches - instinct & learning) 
     IRM explanation/example 
                                             (max 4)
  SELECTIVE ADVANTAGE:
    [Survival ability; e.g., species specificity, avoiding predator, genetically passed-on]
     Stickleback - mating
     escape predators/survival
     save energy/need not learn 
     find food 
     find shelter                                 
                                             (max 4)
