HELP!! physiolab 9.0 Exercise 9 RENAL SYSTEM

9.0 exercise 9: RENAL SYSTEM:  I need help completing this lab....Only about 10 questions i still need. I will even post what I already have to prove I have been working on it. I'll attach the work I already have completed and post on here what I still need.

Here are the questions I need help with.

Activity 1:

According to your lab manual, in humans the glomerular filtration rate (GFR) ranges from _____ to _____ ml/minute.

When the radii of both the afferent arteriole and efferent arteriole were set at 0.45mm, the GFR was approximately ______ ml/minute.
a.40
b.60          
c.80
d.120

Activity 2:

In this simulation, when the radius of the afferent arteriole was 50mm, the radius of the efferent arteriole was 0.45mm, and the beaker pressure was set to 100mmHg, the GFR was approximately _____ ml/min.

When the valve between the collecting duct and the urinary bladder was closed and when the beaker pressure was 100mmHg, the GFR was approximately _____ ml/min and the urine volume was approximately ______ ml.
a.100;  100
b.110;  50        
c.60;  0
d.110;  0

When the one-way valve between the collecting duct and the urinary bladder was closed, what happened to the filtrate pressure in Bowman’s capsule (was not directly measured) and the GFR?

How did increasing the systemic blood pressure alter the results when the valve was closed?

Activity 3:

In this simulation, when the radius of the afferent arteriole was 0.60mm, the radius of the efferent arteriole was 0.45mm, and the beaker pressure was 70mmHg, the GFR was approximately _______ mm/min.

When the radius of the afferent arteriole was 0.60mm, the radius of the efferent arteriole was 0.35mm, and the beaker pressure was 70mmHg, the urine volume changed to approximately ______ ml.
a.50
b.80          
c.200
d.240

Activity 5:

When there were 200 glucose carriers, the glucose concentration in the distal tubule and urinary bladder was approximately
a.0
b.2.5         
c.5
d.10

True or False:  Renal processing of glucose that is filtered in the glomeruli is primarily by secretion back into the blood stream.   

In this simulation, you varied the number of glucose carriers.  When the glucose concentration in the tubules and urinary bladder became zero, the total number of glucose carriers was ______.

Activity 6:

In this simulation, when both aldosterone and ADH were added, the concentration of potassium in the urine increased from approximately 6 to ______.
