Answer:
<h2>Excitatory postsynaptic potential (EPSP)
</h2><h2>a) it brings the postsynaptic membrane potential closer or nearer to threshold </h2><h2>b) it depolarizes the postsynaptic membrane ; and
</h2><h2>
c) it results from the movement of Na+ ions into postsynaptic cell .
.
</h2><h2>Inhibitory postsynaptic potential (IPSP): </h2><h2>a) it moves the postsynaptic membrane potential farther away from threshold .</h2><h2>
b) it hyper-polarizes the postsynaptic membrane ;
</h2><h2>
c) it results from the movement of K+ ions out of the postsynaptic cell
</h2><h2>
In both cases: it is a graded potential in both.
</h2>
Explanation:
Excitatory postsynaptic potentials are excitatory because they make the postsynaptic neuron to generate an action potential by depolarizing the membrane and bringing the membrane potential closer to threshold where new action can generate .It happens by opening ligand-gated Na+ channels in the postsynaptic membrane, which then allows Na+ ions to enter the cell.
Inhibitory postsynaptic potentials make it more difficult for the postsynaptic neuron to produce an action potential by hyper-polarizing the membrane and moving the membrane potential farther from threshold. This occurs by opening ligand-gated K+ channels, which allows K+ ions to move out of the cell.
Regardless of as they are excitatory or inhibitory, all postsynaptic potentials are graded. and by this , its magnitude decreases with distance from the synapse along with the cell body.

Explanation: Hope this helps:)
Arthropods. im not sure if that helps but, thats what they are called.
This is true. Not only are the ores extracted, but everything else is removed with them too, which hurts the soil and the environment with it.
