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:
They were not justified bc they were only tested on animals
Explanation:
Species is defined as a group of organisms that consist of similar individuals capable of interbreeding or exchanging genes among themselves.

Answer: A). 2.7 million people per year
Explanation:
From 2000 to 2010 is 10 years. Change in population in 10 years = population at the beginning of 2010 minus the population at the beginning of 2000. This is:
309 million -282 million = 27 million.
Therefore average change in population person year = 27 million/10 = 2.7 million per year
