How will the non functional sodium channels affect the signaling capabilities of a neuron?

Remember that sodium channels are necessary for action potentials to take place. When a neuron receives a signal from a presynaptic cell, the membrane on the postsynaptic cell depolarized slightly. When this occurs, if the membrane reaches a certain threshold, voltage-gated sodium channels will open, allowing sodium ions to rush into the neuron. If these channels were non-functional, the neuron would be unable to depolarize, therefore inhibiting its ability to produce an action potential. This would keep the neuron from communicating with other cells. I hope this helps you!

answer: grassland biomes are closer to the equator and receive more rain.

grasslands are biomes that are dominated by grasses rather shrubs and trees. savanna are biomes that exhibit grasses, shrubs and small tree as vegetation. grasslands are located near the equator of the earth. these are found in north america. savanna biomes are found in africa, south america, australia and india. grassland exhibit moderate climatic conditions, it receives   amount of rainfall higher than savanna.   therefore, savanna exhibit dry and hot climatic conditions.
