In the Hexapoda, the terms “entognathous” and “ectognathous” refer to the location of the ________________________.

The adults of some fish species live in the ocean, but move to fresh water to reproduce. In these species, larval development takes place in fresh water before individuals migrate to the ocean to live as adults. We would refer to this system as what?

Insects respire using a series of tubes known as _________________.  Some spiders use a similar structure, but many also have a structure unique to spiders called ____________________.   [BlankX] [BlankY]

Vertebrate gills originated in pharyngeal slits used for filter feeding.

Crustaceans are characterized by uniramous appendages.

The largest arthropod subphylum (in terms of species number) is Hexapoda. 

The pupa stage is seen in insects that undergo __________________ metamorphosis, while nymphs are seen in insects that undergo __________________ metamorphosis.     [blank1] [blank2]

In the Deuterostomia, the anus develops from the blastopore.

The calcareous segments that make up the endoskeleton of an echinoderm are called ____________________.

Design a counter that starts at 0 then counts to 7 then counts to 4 then counts to 3 then counts to 5 then counts to 2 then counts to 6. Once it reaches 6 the counter returns to 0 and continues counting in the same manner. Additionally, it must be implemented using S R-flipflops, and answer the following:  Draw the transition graph for the counter. Draw the proper truth table for the present state and next state (make sure the first row of the “present state” start at 000 the next row 001 and so on until the last row is 111 all rows must be written). Draw and fill the proper k-map(s) with all the labels for the next state. Show the proper grouping in your k-map(s) and find the optimal (minimal) SoPs for the next state. Draw the proper truth table for the logic to be connected to each flip flop (make sure the first row of the “present state” start at 000 the next row 001 and so on until the last row is 111 all rows must be written). Draw and fill the proper k-map(s) with all the labels for the logic to be connected to each flip flop. Show the proper grouping in your k-map(s) and find the optimal (minimal) SoPs for the logic to be connected to each flip flop. Draw the logic design of the counter and show the points where you would check the count. When does the counter go to the next value in the count?  Explain. What machine did you just implement?
