Help u can! place the events of a nerve impulse on a neuron in the order that they occur

Neurons receive stimulation causing local potentials until they reach the threshold

Sodium (Na) ions diffuse inward, changing the electric charge of the membrane, depolarizing it.

Sodium channels in the trigger zone of the axon open.

Potassium channels in the membrane open.

When the signal reaches the end of the axon, the synaptic knob releases a neurotransmitter (a chemical messenger) which takes the signal to the next neuron, muscle cell or gland.

The resulting action potential causes a wave of exchanging of ions down the membrane which causes an electric current to travel down the axon.

Potassium (K) ions diffuse outward, repolarizing the membrane.

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.
