well it is not exactly essentioal but salmon need it
The arrival of a neural impulse at the axon terminal causes the release of neurotransmitter from the synapse.
<h3>What are neurotransmitters?</h3>
A neurotransmitter is indeed a signaling molecule that a neuron secretes to affect some other cell all over a synapse.
The cell that receives the signal, which could be any major body part or target cell, could be another neuron or a gland or muscle cell.
An action potential travels the length of an axon and causes neurotransmitter release at the synapse.
The neuron can interact with other neurons thanks to the action potential and subsequent transmitter release.
Thus, the correct answers are neurotransmitter and synapse respectively.

1. What is the relationship between chromosomes and DNA? The chromosome is a molecule formed by a chain of DNA associated with proteins. Together, they form a group of molecules directly responsible for heredity.
2. What is heredity? It is the biological process where the genes present in a DNA are transmitted by parents to their children, through the division of gametes. These genes carry the codes that form the genotypic and phenotypic characteristics, which allows a similarity between parents and children to occur.
3. What is the role of proteins associated with the DNA molecule that makes up the gene? Proteins are responsible for keeping the DNA line tightly compressed, maintaining the chromosome structure. In addition, they control the activities of the genes present in this DNA molecule, being essential in maintaining heredity.
4. How do chromosomes participate in gene transmission? As mentioned above, genes are part of DNA and DNA is the molecule that makes up chromosomes, in this case, chromosomes are molecules loaded with genes. In the human body, cells have 46 pairs of chromosomes, with the exception of gametes that have half that number. During the reproductive process, the gametes (reproductive cells) divide and produce a new being. The mother's gametes unite with the father's gametes to form a new being. Each gamete has 23 chromosomes, which contain the genes responsible for transmitting the characteristics.
OK so when a rock is weathered down this is a physical type of weathering.
If a chemistry student is given a molecular formula of a molecule, she or he can easily and readily identify if it is compound by checking the bond either a covalent bond or ionic bond. Check the items of each element since elements in a compound are in fixed ratio, she or he can easily identify.
