Did the inspiratory reserve volume increase, decrease, or not change with exercise? decrease with exercise 5. Did the inspiratory capacity increase, decrease, or not change with exercise? increase with exercise 6. Did the functional residual capacity increase, decrease, or not change with exercise?
Why do you think the plot was not linear? (Hint: Look at the relationship of the variables in the equation.) How well did the results compare with your prediction? The increase in radius resulted in an increase flow rate, as predicted. ACTIVITY 2 Studying the Effect of Blood Viscosity on Blood Flow Rate 1.
Based on changes in amplitude and frequency of sEMG, did motor unit activation increase, decrease, or stay the same with increasing muscle load? The motor unit activation increased with muscle load based on the changes in amplitude and frequency of sEMG because the motor units which are activated are contracting at a greater frequency. 8. Do you think that the force of isometric contraction increased, decreased, or stayed the same as muscle load increased? The force of the isometric contraction increased as the muscle load increased.

Running Lady Experiment Aim: To investigate and observe the differences between constant velocity and increasing and decreasing velocity, by carrying out the Running Lady Experiment. Hypothesis: | Constant Velocity | Increasing Velocity | Decreasing Velocity | Displacement v Time | Displacement Time | Time Displacement | Time Displacement | Velocity v Time | Velocity Velocity Time | Time | Time Velocity | Graph 1: That a constant velocity will equate to a constant increase when graphed as Displacement v Time. That the slope of the graph will remain constant throughout, indicating a steady or constant velocity. Graph 2: That an increased velocity will show a slight curve on a positive slope as the displacement gets slightly increased whilst time is constant, demonstrating increasing velocity situations. Graph 3: That a decrease in velocity will show a slight downward slope toward the middle of the line as displacement decreases as time remains constant.
Was the rate of increase of sucrase activity higher at a pH of 8.5 or a pH of 5.5? 3. State the optimum temperature for sucrase activity, and describe how sucrase activity changes at lower and higher temperatures. The optimum temperature for sucrase activity is 40˚ C. Sucrase activity drops at lower and higher temperatures (it kind of levels out with minimal change at higher temperatures but is still dropping). See Table 3: Effect of Sucrose Concentration on Sucrase Activity See Graph: Effect of Sucrose Concentration on Sucrase Activity 4.
