Describe the mechanism for reabsorption

Henle, permeability
of
the descending limb, impermeability
of

What role does
ADH
play in this?
Turn in your cladogram
of
all the phyla (the one I told you to compile from all the
cladogram sheets). Try to fold it up neatly. Make sure your name
is
on
it.
You may re-write it
if
you
wish to, but I suggest you simply turn it in
as
is
.. . I am
not
looking for neatness
exactly, more at the different synapomorphies and autapomorpies, how you showed the
branching, and how prepared you came to this exam.
If
you didn't do it, do it
now
but
you
have to do it from memory

this
is
a closed book exam. 35 points
