Why does the crystals start toform as the solvent cools?

Crystals begin to form as the solvent cools because the solubility of the solute decreases with temperature. As the solvent cools, it can no longer hold as much dissolved solute, leading to supersaturation. This excess solute starts to aggregate into a solid structure, forming crystals. Additionally, lower temperatures reduce the kinetic energy of the molecules, allowing them to arrange into an ordered crystalline pattern more easily.

When two action potentials arrive simultaneously at two different presynaptic terminals that synapse with the same postsynaptic neuron?

When two action potentials arrive simultaneously at different presynaptic terminals synapsing with the same postsynaptic neuron, the postsynaptic neuron may experience a phenomenon known as spatial summation. This occurs when the excitatory postsynaptic potentials (EPSPs) generated by each terminal combine, potentially reaching the threshold for triggering an action potential in the postsynaptic neuron. If the combined effects are sufficient, the postsynaptic neuron will fire an action potential; otherwise, it will remain at its resting potential. This process enhances the likelihood of neuronal activation in response to multiple inputs.
