I actually like it!! very interesting to know this stuff, for me anyways.. Wink Congratulations

1.    Hypertension means:

b.   High blood cholesterol levels
c.   High blood pressure levels
d.   None of the above

2.    A sphygmomanometer:
a.    Measures blood pressure
b.   When inflated cuts off blood flow to the brachial vein
c.   Should be used in conjunction with a stethoscope to obtain an accurate BP reading.
d.   A and C
e.   All of the above

3.    In measuring blood pressure:
a.    Diastolic pressure is measured as blood first reenters the artery
b.   Systolic pressure is measured when blood flow just returns to normal in the artery
c.   Blood pressure readings are noted as systolic over diastolic pressure
d.   All of the above

4.   Based on the laboratory activity, evidence shows that as a group:
a.    Males experience an increased systolic and diastolic pressure with age
b.   Males experience a decreased systolic and diastolic pressure with age
c.   Males experience an increased systolic and decreased diastolic pressure with age
d.   Males experience a decreased systolic and increased diastolic pressure with age
e.   Males have relatively constant blood pressure with age

5.    Based on the laboratory activity, evidence shows that as a group:
a.   Females experience a decreased systolic and diastolic pressure with age
b.   Females experience an increased systolic and diastolic pressure with age
c.   Females experience an increased systolic and decreased diastolic pressure with age
d.   Females experience a decreased systolic and increased diastolic pressure with age
e.   Females have relatively constant blood pressure with age

6.   On average for both sexes, normal blood pressure is typically defined as:
a.    140/60
b.   130/95
c.   120/80
d.   145/80

7.    Based on the results of this exercise, which of the following blood pressure readings are significantly above normal, indicating hypertension?
a.    122/78
b.   130/84
c.   129/81
d.   None of the above

8.    Which of the following information from the medical charts appears to play the least role in determining blood pressure?
a.    Sex
b.   Height
c.   Weight
d.   Age
e.   None of the above

9.   Which of the following appear to be lifestyle related risk factors for hypertension?
a.    Smoking
b.   Lack of exercise
c.   Salt intake
d.    A and B
e.   All of the above

10.    A patient comes in to have their blood pressure taken.  They are a non-smoker, they exercise daily and consume a healthy diet low in sodium.  Based upon this information:
a.    Their blood pressure will be normal
b.   Their blood pressure will indicate hypertension
c.   You cannot estimate their reading due to the effect of genetics on blood pressure


11.   What factors are known to cause increases in blood pressure?

12.   Use your knowledge about the heart and the circulatory system to make a hypothesis about how the average blood pressure for a group of people would be affected by manipulating the age and gender of the group members.

13.   What sorts of problems might a person develop who has chronic hypertension?

14.   Analyze the result of your experiment. Explain any patterns you observed.

15.   Did the result of your experiment support your hypothesis? Why or why not? Based on your experiment, what conclusion can you draw about the relationship of age and gender to group blood pressure averages?

16.   During the course of your experiment, did you obtain any blood pressure readings that were outside of the normal range for the group being tested? What did you notice on the medical charts for these individuals that might explain their high readings?

17.   List risk factors associated with the hypertension. Based on your observation, which risk factor do you think is most closely associated with hypertension?

18.   What effect might obesity have on blood pressure? Does obesity alone cause a person to be at risk for high blood pressure? What other factors, in combination with obesity, might increase a person's risk for high blood pressure?


thats just the blood pressure one... Wink

Please can someone help me with the lab 5 Alters and Alters.

Table 1:
*Results will vary depending on the samples chosen by the computer.

Day   P. caudatum alone, cells/mL
(from tt#1)   P. aurelia alone, cells/mL
(from tt#2)   P. caudatum mixed, cells/mL
(from tt#3)   P. aurelia mixed, cells/mL
(from tt#3)
0            
2            
4            
6            
8            
10            
12            
14            
16            


Lab Questions:

1.   Make a hypothesis about how you think the two species of paramecia will grow alone and how they will grow when they are grown together. (6)


2.   Explain how you tested your hypothesis. (6)


3.   On what day did the Paramecium caudatum population reach the carrying capacity of the environment when it was grown alone? How do you know? (6)


4.   On what day did the Paramecium aurelia population reach the carrying capacity of the environment? How do you know? (6)


5.   Explain the differences in the population growth patterns of the two paramecium species. What does this tell you about how Paramecium aurelia uses available resources? (6)


6.   Describe what happened when the paramecium populations were mixed in the same test tube. Do the results support the principle of competitive exclusion? (6)


7.   Explain how this experiment demonstrates that no two species can occupy the same niche. (6)


8.   Paramecia possess (2):
a.    Flagella
b.   A contractile vacuole
c.   All of the above

9.    The organisms used in this experiment belong to which domain of life? (2)
a.    Bacteria
b.   Archaea
c.   Eukarya

10.   What served as the food for the paramecia in this experiment? (2)
a.    Rice
b.   Oats
c.   Bacteria
d.   Nothing, they are photosynthetic

11.   Which of the following can influence the carrying capacity of a population? (2)
a.   Availability of food
b.   Availability of water
c.   Competition
d.   Build up of toxins
e.   All of the above

12.   Which type of competition would be observed between organisms within the P. caudatum culture? (2)
a.    Interspecific
b.   Intraspecific
c.   There would be no competition, they are of the same species

13.     Which culture reached its carrying capacity the fastest in this experiment? (2)
a.    P. caudatum, alone
b.   P. aurelia, alone
c.   P. aurelia, mixed

14.   You have counted 30 organisms in your culture on Day 4.  The concentration of organisms in this culture is (2):
a.    15 cells/mL
b.   30 cells/mL
c.   60 cells/mL
d.   90 cells/mL

15.    Based upon your data, which culture experienced the greatest rate of exponential growth? (2)
a.    P. caudatum, alone
b.   P. aurelia, alone
c.   P. caudatum, mixed
d.   P. aurelia, mixed

16.    Based upon the data, which organism appeared more efficient at using its resources? (2)
a.     P. caudatum
b.    P. aurelia

17.   In a repeat of this experiment, you found that on Days 10-16 the number of individuals in the P. caudatum, mixed culture began to gradually rise.  A possible explanation for this is (2):
a.    There was insufficient food in the culture
b.   The temperature warmed enough to allow for more growth
c.   A genetic variant of the original population began to experience growth due to its use of a different food (bacterium) source
d.   None of the above could lead to this scenario


Question Type   Point Value per Question   Total Possible   Your Score
