I need some help with my lab (please see the attachment )

Could you write the questions out...

ACTIVITY 6:  The Skeletal Muscle Length-Tension Relationship
33.   In a force-length graph,
a.   the muscle length is the independent variable.   
b.   the amount of force generated is the dependent variable.
c.   both active and passive forces must be considered.
d.   All the above are correct.   
34.   According to your lab manual, the protein titin is the primary cause of _________ __________.   
35.   In this lab simulation, the muscle length of _______ mm was able to generate the largest active force.   
36.   The force that results from muscles being stretched is called
a.   active force.
b.   passive force.         
c.   maximal tetanic force.
d.   stretch force.   
37.   What happens to the amount of total force that the muscle generates during the stimulated twitch?   
38.   Based on the unique arrangement of myosin and actin in skeletal muscle sarcomeres, explain why active force varies with changes in the muscle’s resting length.   
39.   What range of skeletal muscle lengths generated passive force?     
40.   If you were curling a 7-kg dumbbell, when would your bicep muscles be contracting isometrically?   
ACTIVITY 7:  Isotonic Contractions and the Load-Velocity Relationship
41.   The fastest muscle contraction velocity measured in this part of the simulation occurred with the ______ weight.
a.   2.0 gm
b.   1.5 gm         
c.   1.0 gm
d.   0.5 gm   
42.   The fastest muscle contraction velocity in this simulation was approximately ________ mm/msec.   
43.   True or False:  A muscle that is contracting isometrically will fatigue much slower than one that is contracting isotonically.     
44.   If you were using your biceps muscles to curl a 7kg dumbbell, when would your muscles be contracting isotonically?   
45.   Explain why the latent period became longer as the load became heavier in the experiment.   
46.   Explain why the shortening velocity became slower as the load became heavier in this experiment.   
47.   Explain why it would take you longer to perform 10 repetitions lifting a 10kg weight than it would to perform the same number of repetitions with a 5kg weight.   
48.   Describe what would happen in the following experiment:  A 2.5g weight is attached to the end of the isolated whole skeletal muscle used in these experiments.  Simultaneously, the muscle is maximally stimulated by 8.5 volts and the platform supporting the weight is removed. 
a.   Will the muscle generate force?
b.   Will the muscle change length?
c.   What is the name for this type of contraction?   

The velocity possible in lifting a 20-pound weight is much less than that of lifting a 5-pound weight.


The lighter the weight, the greater the initial velocity of shortening; inverse relationship.
