PhysioEX exercise 3 activity 6

Here is the whole activity.

thaankk you so much!!

Mark as solved if this is what you needed.

Fantastic, appreciate the chance to check my work

I have unfortunately come up with the same problem with Exercise 3 Activity 6. After completely the pre-lab Quiz, it goes into the experiment, fast forwards to step 2, tells me to click on "record data" and then refuses to let me do anything else. Very frustrating. Hopefully your attachment will help me. Thanks in advance!

I can't see to open it.

Thank you for this!!!

thanks for the help, i was finding this one difficult

Post-lab Quiz Results You scored 100% by answering 4 out of 4 questions correctly.
1.   If the interval between action potentials (the interspike interval) is 0.1 (1/10) seconds, what frequency of action potentials would be observed? You correctly answered: c. 10 Hz
2.   With a prolonged stimulus that is just above (more depolarized than) threshold, you would expect to get additional action potentials when the membrane has completed You correctly answered: b. the absolute and relative refractory periods.
3.   Which of the following changes occurs when you increase the stimulus intensity? You correctly answered: c. The frequency of action potentials increases.
4.   The absolute refractory period is about 3.75 msec. What intensity stimulus would produce action potentials with this interspike interval? You correctly answered: d. None of these stimuli would produce action potentials at this high frequency.

I have almost all of the pre and post quiz results posted.

Thank you so much. This was a very confusing activity!

Im also having trouble with this one 

I guess i am not the only one whose activity 6 wont work
this is cool though, didn't know this cite was available.
