No one is posting. I'm sorry, I'm lazy.
If you still don't know who I am (waycider), I'm Marianne. Nico is incredible incarnation.

BIO (due Wednesday)
The Heartbeat
1) What is the importance of the delay of impulse transmission from the atria to the ventricles?
2) What will happen if I cut the left bundle? The right bundle? A Purkinje fiber?
3) Explain this phrase, "A person that is brain dead is a live, a person that has a dead heart is dead".
The electrocardiogram (ECG)
1) Why is there a difference in the amplitude between P wave and QRS complex? (hint: energy produced)
2) Relate this difference to the structure and function relationship of the structures involve.
The Law of Continuity
1) If a fluid tends to move faster in a smaller container, does the movement of blood within the capillaries violate this law?
2) Based on your answer in #1, relate the structure to function relationship in a capillary using the law of continuity.
3) What is the relationship of diffusion and rate of blood flow?
Transfer of substances in a capillary
1) How does the constriction and contraction of the arteriole and the pre-capillary sphincter increase blood pressure at the arterial end of the capillary?
2) How are wastes transported back to the blood from the surrounding metabolizing cells?
3) Why is there a need to prevent the blood proteins from moving out of the capillaries?
4) What are the ways to transport a substance from the capillaries to the surrounding cells?
PHYSICS
We have this one Physics handout (the 5-page one, due same time as prob set) and another sheet with directions for the prob set.
A. Reference: Physics by Giancolli, 3rd edition. Solve the following problems:
Prob. 8 (p.92); 4 (p.230); 22 (p.93)
39,43 (p.95); 50 (p.96)
1. Use sheets of intermediate paper for this problem set using this format:
Name Class No.
Yr/Section Date
Phy2 Q2_PS1 - Linear Dynamics
2. Write the problem. After the problem, follow the format in problem solving:
a) Illustration -> b) Given -> c) Find -> d) Derivation -> e) Substitution -> f) Final Answer
3. Follow rules of sig figs. Include units in solutions.
4. Deadline: 07 September 2011 (before LT1). Late submissions NOT ACCEPTED.
5. Demerits given for every direction/reminder not followed.
I would have copied the questions here, but I own the 5th edition... Anyone else?
ENGLISH
We got our new groupings and stories for reporting.
The req reading for this quarter is The Last Time I Saw Mother by Arlene Chai. [If anyone is still buying copies, could you get me one, too? I've been to four bookstores and I can't find anything.]
I think we need a representative for the rap contest? Blaaarg.
FILIPINO
See LJ's Di-Kum post below.
No, the rap contest is for the whole class. It's a house thing.
