1. What would happen to blood flow if pressure
increased? Decreased? What would happen to blood flow if
resistance increased? Decreased?
2. What kinds of things affect resistance in blood
vessels? Which one of these has the greatest effect? Explain
why in terms of laminar flow.
6. Nicotine is a vasoconstrictor. What would you expect to
happen to the blood pressure of a chronic cigarette smoker? Explain
your answer.
7. Does a person with a very high post-exercise heart rate have
a high or low oxygen debt?
Using the AD-AS model, graph and explain what would happen to
unemployment and inflation in the following situations.
a) Assume the economy begins at potential output. Consumer
confidence rises. What is the short run effect?
b) Starting with the previous question, consumer confidence
rises. What is the long run effect?
Using your understanding of plant cell structure, explain what
you are seeing in the difference between Elodea cells placed in
pond water compared with cells that have been submerged in 5%
NaCl.
2. Briefly explain how kinetic energy contributes to Brownian
motion (the visible or measurable physical movement of all
molecules and compounds), and how this helps explain diffusion and
osmosis.
Using Grossman model explain what would happen to the demand for
health stock.Assume that John was working as a construction worker
that is a very physically demanding job (meaning high depreciation
rate of health). He was able to find another job in an office that
would provide the same income but it is much safer and less
physically exhausting meaning that his health depreciation rate is
now lower. What would happen to John's demand for health stock?
Draw a figure...
You
have not eaten all day and your blood sugar is low. What needs to
happen to raise your blood glucose levels. You must include all
hormones and organs to get full credit.
Using Grossman model explain what would happen to the demand for
health stock as people get older and their preferences for health
change. Assume that older people value health more than younger
people. Draw a figure showing initial MEI, Marginal Costs and
initial level of health stock. Then demonstrate appropriate
changes/shifts in MEI, MC, and optimal level of health stock
relative to the initial. Upload your picture here.
Explain what the difference is between a process and a
program.
Explain what would happen if a parent process exits immediately
after calling the fork() system call.
