The "All or None" response means that:
A stimulus causes depolarization and repolarization regardless of the strength of
the stimulus
There is no threshold for an electrical stimulus signal to reach before
depolarization and repolarization
O Potassium channels open for depolarization and sodium channels open for
repolarization
A stimulus has to be strong enough for depolarization to occur followed by
repolarization
If the response to a stimulus is a change from a negative potential to a less negative potential, the change is called:
stimulus response
Repolarization
Depolarization
Stimulus recovery
In a negative feedback loop, the effector moves the system in the direction as the stimulus.

- List four factors that might influence the reaction time to a stimulus .Consider the ruler drop response time test you performed; do you believe it was valid and reliable? Why or why not ? Provide justifications for your answer. [Hints: Here are a few ideas. Will you conduct many tests on the same subjects (that means the people you are testing))? Is it necessary to use averages? Are there any precautions to take? [Are there any variables that must remain constant?]arrow_forwardIn negative feedback systems the receptor sends a negative signal the stimulus is increased or amplified the effector reduces or eliminates the stimulus the control center receives input from the effector the receptor increases or enhances the stimulusarrow_forwardImagine you are conducting a beta fish experiment.

- Four research teams measured the speed at which signals travel down a certain type of nerve fiber, and what each team wrote in its team notebook is shown in the table below. Suppose a later and more reliable measurement gives 111 m/s for the signal speed in the same type of nerve fiber. Decide which of the earlier measurements was the most accurate, and which was the most precise. what was written most accurate most precise team in the notebook ? measurement measurement A "101.m/s" В "91.m/s + 5.0m/s" C "131.m/s + 2.0%" D "between 106.0m/s and 126.0m/s"arrow_forwardDefine sensorsarrow_forwardA neurotransmitter binds to a receptor on a muscle cell and causes sodium channels to open.

O is weak and depending on the stimulus strength will maintain its strength as it travels. O is all-or-none, and maintains it strength as it travels. O is all-or-none but weakens as it travels.arrow_forward
