Explain the connection between competition and deadweight loss
by comparing a highly competitive market with a highly
uncompetitive market. Explain the roles of incentives and
consumer/producer surplus.
Cytokines are regulatory proteins that act as signals between
cells, creating a network for cell to cell signalling. Cytokines of
the immune system are:
Interleukins which signal among leukocytes. At least 37 human IL
have been identified.
Interferons (IFN) gamma IFN activated phagocytes and is secreted
by T helper cells. Review the fucntion of IFN type I in chapter
15.
Growth factors stimulate leukocyte stem cells to divide and help
with proliferation of certain cells of the immune system.

What is the difference between how B Cell and various T Cells
are produced and what is their associated function in the body’s
innate or adaptive immune system? Give examples.
Cytokinesis (the splitting of cells after mitosis) differs in
detail between different cell types. In simple terms, how does
cytokinesis occur in plant cells, animal cells and yeast cells? Why
would the process be different in these organisms?
Tight junctions:
a. allow communication between cells and an exchange of ions
b. cause cell membranes to tightly fuse together
c. extend around the cell like a belt
d. connect adjacent cells and their cytoskeleton
e. all of the above
Name the type
of cell junction(s) most likely found between cells of these
organs. Explain your logic.
