It's the sodium ion.
When a neural impulse is fired in both neurons, it is always cause by an excited electron in one neuron moving to the other neuron to destabilize the balance of ions trying to keep them at equilibrium. This action either depolarizes or hyper-polarizes the membrane. If it does, then sodium ions--the key deficient ones--can flow into that region of low charge and maintain that state of low charge, keeping the cell membrane stable.
Dehydration synthesis :) it means that monomers (like glucose or lactose) when bonded together release water molecules
<span>These are viroids. They are some of the smallest types of matter that have been shown to take on the properties of living beings. They have the ability to replicate, while not having many of the mechanisms that are commonly found in DNA and required for them to replicate.</span>
B. they are both unicellular
