Answer:
Explanation:
Acetylcholine (ACh) is an organic chemical that functions in the brain and body of many types of animals (and humans) as a neurotransmitter.
Neurotransmitter is a chemical message released by nerve cells to send signals to other cells, such as neurons, muscle cells and gland cells.
After a neurotransmitter molecule has been recognized by a post-synaptic receptor, it is released back into the synaptic cleft. Once in the synapse, it must be quickly removed or chemically inactivated in order to prevent constant stimulation of the post-synaptic cell and an excessive firing of action potentials.
Some neurotransmitters are removed from the synaptic cleft by special transporter proteins on the pre-synaptic membrane. These transporter proteins carry the neurotransmitter back into the pre-synaptic cell, where it is either re-packaged into a vesicle and stored until it is once again needed to transmit a chemical message, or broken down by enzymes.
They will start to get very mushy, but they will stay at room temperature.
<span>The most primitive vertebrates whose reproductive pattern includes the amniotic eggs are the reptiles.
An amniotic egg is filled with amniote, which are these membranes that have fluid in them. They serve to protect the embryo and enable it to survive any harsh conditions that may harm it. These cells have protein shells as well as calcium that provide further protection.
