B.An action potential moves along the neuron.
a action potential forms.
Ions flow into the neuron.
When a neuron sense a stimulus, it will open ion canal and allow ion to flow into neuron causing a change in membrane potential. This will activate a cascade of reaction which needed to sent message to other neurons.
on the planet jupiter, the acceleration due to gravity is approximately 26 m s2 , roughly 2.7 times the acceleration due
