You might want to actually write your answers in Word (so you can spell
check them) and then cut-and-paste into the boxes. That way, if the computer
misplaces your work you can just re-paste the answers.
Although you could in theory work from home, the simulation is only
available on the school's network. .

Answer the questions as best you can. The boxes will expand as you type if you need more space.
(Don't worry if it is a one word answer. The box size is standard.)
Since you will be working in groups, put all the names of the people in the
group in the box. The ideal group size is 2. As an exception I will allow groups
of 3. No groups of 4 or 5. If you work as a group of 3 I expect better answers.
Group sizes above 3 will be penalized in the grading.
To answer these questions you can
(1) do the simulated lab in APLab10 in "shortcut to shortcuts"
[You do better to start this from "shortcut to shortcuts" rather than from this a
(2) do the simulated lab at lab bench

Question 1: Explain why blood pressure and heart rate differ when
measured in a reclining position and a standing position.
Question 2: Why is high blood pressure a health concern?
Question 3: Explain why an athlete must exercise harder or longer to
achieve a maximum heart rate than a person who is not as physically fit.
(Include a discussion of how long you think it takes Dr. G to reach maximum
Question 4: Why do you think smoking causes a rise in blood pressure? (This
may require outside research. If you don't finish in class time, you can enter
the answer to this question on its own later).
Question 5: Describe the shape of a graph where temperature is the dependent
variable and heart rate is the independent variable for Daphia.
Question 6: Why does temperature affect heart rate in ectothermic organisms?
Question 7: What do you think would happen if you did the same type of
experiment on an endotherm (say a person)? Why?
Question 8: Discuss how an ectotherm might use behavior to regulate its
temperature. Include at least 4 different ways. (Think summer homework. Think
