When the daughter cell splits or divides from the parent cell, it is called <span>cytokinesis.</span>
dont tell me why but, what does diatoms have to see with petroleum? well, i think is "e" cause it has almost no relationship according to my thoughts
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.
All arthropods are invertebrates with an exoskeleton, segmented body, and jointed appendages.
Answer:
D. G2 phase and M phase
Explanation:
<em>If we are looking for what takes up 25% of the graph, that would be the last option. If you look at G1, it takes up about 50%. So</em>, G1 phase and M phase <em>would take up more than that, and we want 25% not 50+. The </em><em>M phase and S phase</em><em> would take up about a third, so no. The </em><em>G2 phase and M phase </em><em>takes up roughly 25% or, it's the closest to this.</em>
