the Pre-lab Quiz. 07/08/13 page 1 Experiment Results Predict Question: Predict Question: As the resting length of the muscle is changed‚ what will happen to the amount of total force the muscle generates during the stimulated twitch? Your answer : d. An increase in muscle length will decrease the total force. Stop & Think Questions: Note the dip in total force at a muscle length of 90 mm. Why does this occur? You correctly answered: d. At this muscle length‚ active force has decreased in

Premium Diffusion Osmosis Molecular diffusion
Describe two variables that affect the rate of diffusion. Your answer: The two variable that affect the rate of diffusion are as follows: -the composition of the lipid layer which can vary from tissue to tissue -the size of the molecule(the larger the size the slower the rate of diffusion) 2. Why do you think the urea was not able to diffuse through the 20 MWCO membrane? How well did the results compare with your prediction? Your answer: The urea was not able to diffuse through 20 MWCO membrane
