Georgio is jogging barefoot along the beach when he suddenly steps on the sharp edge of a broken shell. He instantly feels pain due to the message carried to his brain by<u> dendrites.</u> He then slowly walks home with an achy foot. The message of the ache is carried by <u>neurons.</u>

The nervous system has electrical cells that are trained to transmit and receive messages. Through the use of electricity, people can communicate by transmitting messages to one another. This voltage is produced in neurons by the movement of charged ions. salt atoms with positive or negative charges that pass through the cell membranes and cross the cell's outer membrane. The neuron has dendrites, which are branches (like a tree) that receive messages, and an axon, which is a longer, more straightforward projection (like a tree trunk), that sends information. Synapses. Axon ends include the neuron communication junction, where vesicle fusion releases chemical signals. Neurotransmitters are the chemical messages that the nerve cell releases.

Answer:
<em>condensation or dehydration synthesis</em>
Explanation:
A condensation reaction can be described as a reaction in which two molecules combine to form a larger molecule. A water molecule is usually dispersed during this reaction.
For example, two amino acids join to form a protein. The bond formed between them is known as dipeptide bond.
Dehydration synthesis is also a reaction in which molecules via covalent bonds to form larger molecules. As water molecule is released during this process, this reaction is termed as dehydration synthesis.
<u>Answer:</u> A. Pluripotent
Reasoning: Brain stem cells can only make different types of brain cell
