Answer:
In a postsynaptic cell/neuron where a depolarizing change in the membrane potential surpasses the threshold.
Explanation:
Generally, in an excitable cell, the neurotransmitter binding opens the ligand-gated channels at the synapse. Here only the entrance of the ions will not stimulate the action potential. They must exceed the threshold. Hence, an action potential will only get incited when in a postsynaptic cell/neuron, a depolarizing change in the membrane potential surpasses the threshold.
Answer:
Explanation:
The biome would be the arctic tundra - as it states the weather is cool
For hot summer, I would say forests because it inmcludes trees and crops
Water, air, food. and heat.
The first answer is correct.
