So its late and i'm running on fumes. i need help with the last few questions in the activity and then i'm done. please help if you can. it would be much appreciated.

#56: Describe what happened when you applied a very weak stimulus to the sensory receptor?

#57: Describe what happened when you applied a moderate stimulus to the sensory receptor?

#58: Identify the type of membrane potential (graded receptor potential or action potential) that occured at R1, R2, R3 and R4 when you applied a moderate stimulus. (compare/view the response to the stimulus)

#59: Describe what happened when you applied a stong stimulus to the sensory receptor?

I have a general idea, but the terms kill me. This is my first science class in a long while so I may have jumped in a bit over my head, but i'm somehow keep afloat. please help. Thanks

When you applied a moderate stimulus to the sensory receptor, a larger, depolarizing response occurred at R1, and an action potential was generated at R2 and at R4.

A graded stimulus was recorded at R1 and at R3; an AP was recorded at R2 and at R4.
