yes but I don't know what it has to do with the stretch reflex

thank you :biggrin:

Can someone explain it to me? I know it goes from the brain to the spinal cord but what does it have to do with the stretch relex?? Thanks

ANOTHER QUESTION: I read that "because of the absolute refractory period of the Na+ voltage-gated channels, two action potentials cannot be fired one on top of the other. Therefore, action potentials will almost always have a fixed height or amplitude" Can't an action potential be fired...

1. How does an Action potential start in the nerve. Does it just receive a stimulus and suddenly the inside of the nerve depolarizes??:confused: How does the inside of the nerve become more positive?? 2. In people with Multiple Sclerosis the myelin on the nerve is broken down & the AP doesn't...

Does anyone know where I can find more information on Myopia (nearsightedness). I want to know why light rays focus in front of the retina and if this is genetic or not. This has to do with physics because of the light and how it moves. I need more detailed but simple information.

rate equation is: r= k[x]^n ...I don't get it for this lab its r = k[IO3]^2 right?

We did an experiment where we mixed Solution A with Solution B and found out the time. These are my results: Solution A (0.020 mol/L potassium iodate solution plus distilled water) 10 drops potassium iodate plus 0 drops distilled water 9 drops potassium iodate plus 1 drops distilled...

wow thanks Shawn. It explains a lot :biggrin:

it was a solution. I asked the teacher and got it thanks everyone

I need to calculate heat generated so I'm using this formula: q=mc(delta)t and i need c

i can't find it on there? :confused:

Thank you :biggrin: Gokul43201 - yes I do

Whats the heat capacity of NaOH I can't find it anywhere?

I keep getting confused on which formula to use where. q = mc(delta)t (delta)H = n(delta)Hx n(delta)H = mc(delta)t I don't know which ones to use, I keep using the wrong formula.. :cry: How do I know the difference?
