Question 1
What are the
advantages and disadvantages of a life style as an ectotherm? Consider
thermoregulation, metabolism, respiration, circulation, and any other
physiological adaptations. In which type of environment would it be best
to be an ectotherm? How have ectotherms in the arctic adapted to
survive?
Question 2
Your best friend at SBCC is from the
Andes mountains in Peru. She is 12th the generation Peruvian, and was
born and lived her first 18 years of life in Cusco, Peru at 11,000 feet.
You are 8 the generation Santa Barbarian and have lived here your whole
life. You two run the SBCC track together every Tuesday and Thursday
but you can never run as fast or as far. Compare your physiology to hers
and explain why. What happens physically and physiologically to you
when you go home with her for the summer?
Question 3
You
lost your pet dog At Joshua Tree National Park on Father’s Day weekend
(the desert with averagedaily temps of 120°F). What physiological
struggles will your pet have? What might they do to cope? Consider its
thermoregulation, metabolism, behavior, and other physiological effects.
Question 4
Honey,
I shrunk the kids! Apart from the obvious challenges of vacuum cleaners
and predatory house cats, consider the physiological changes that would
occur, or that would be necessary for normal body function, if these
children were miniaturized to about 1/100 original body size (in direct
1:1 proportion). Discuss in detail physiological changes or problems
related to metabolic rate, scaling of physiological processes,
temperature regulation, osmoregulation, energy intake, respiratory
physiology, and/or any other area of environmental adaptation discussed
this semester. You may assume that these children are in a comfortable
home (about 75°F) and encounter periods of strenuous exertion when
evading predators.
Question 5
Pretend we are friends at a
cocktail party and I ask you about your semester. You are so excited
about your animal physiology class and cannot wait to share three really
interesting things you learned. Go for it! Tell me what this exciting
new bit of knowledge is and explain it so your accounting major friend
can understand. Please provide enough detail so I can learn something
and understand.
Just instructions from my professor.
(You MUST answer in your
own words. Any bit of plagiarism will result in a zero for the entire
exam. Please be thorough and provide as much detail as you can without
adding ancillary facts that do not add to the answer. In other words, be
direct but detailed. These questions are intended to make you think and
start to put the different concepts together to come up with well
thought out, coherent answers.)
