What is the term used to describe the minimum level of stimulus required to activate a neuron?
a. action potential
b. threshold
c. resting potential

The correct answer is -

b. Threshold.

Explanation:

Threshold can be described as minimum voltage of a memrane (of neuron or muscle cell) that is required to reach an excited state of cell during a depolarization) so as to produce an action potential.

Voltage-gated channels are activated at the threshold voltage, .

For example - Threshold level of neuron is - 55mV, which means it fires action potential at this level so that information is transferred to another neuron.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
