5 Points
(each error costs 0.25 point)

1.   Identify which part of the nervous system innervates each of these structures:
   Legs
   Antennae
   Ocelli
   Wings
   Cerci
   Mouthparts


2.   Identify which type of receptor is used to detect each of the following.  Use "M" for mechanoreceptor, "C" for chemoreceptor, or "P" for photoreceptor:
  Wind speed Pressure
  Balance Airborne sounds
  Humidity Polarization of light
  Colors Substrate vibration
  Taste Smell (odors)


3.   Put a check mark by each insect that has compound eyes:
Grasshopper nymph Beetle adult
Caterpillar larva Stonefly adult


4.   Put a check mark by each insect that has lateral ocelli (stemmata):
Grasshopper nymph Beetle adult
Caterpillar larva Stonefly adult


5.   A fixed action pattern is a stereotypic unit of    behavior that is programmed    and always performed in response to a key stimulus known as a(n)  .


6.   Put a check mark by each behavior that is likely to be learned:
Response to sex pheromone of potential mate

8.   Put a check mark by each tactic insects may use to communicate with each other:
Chemical odors Text messaging
Sound vibrations Physical movements
Flashes of light Color patterns


9.   Between individuals of a single species, a chemical signal is called a(n)   .   Between members of different species, however, it is known as a(n)     if it benefits the sender but a(n)     if it benefits the receiver.
