Neurotransmitters. With the regard to the process of the neural transmission, a refractory period refers to the time in interval in which. the Positively charged sodium ions are to pumped back to outside a neural membrane.
Neurotransmitters are the chemical messengers that your body can't function without it. Their job is to carry out chemical signals (“messages”) from one of the neuron (nerve cell) to the next target cell. The next target of the cell can be another nerve cell, a muscle cell or the gland.
Fortunately, the seven “small molecule” are neurotransmitters (acetylcholine, dopamine, the gamma-aminobutyric acid (GABA), or glutamate, histamine, norepinephrine, and the serotonin) do the majority of the work.

The biological species concept proposed by Mayr states that a biological species is a population whose members can interbreed and produce fertile offspring.
<h3>What is the biological species concept?</h3>
The biological species concept is a model used in biology sciences to delimit a species through mating fertile features of the individual that belong to such species.
This concept (biological species concept) was proposed by Ernst Mayr to understand how each species represent a functional unit.
In conclusion, the biological species concept was proposed by Mayr and states that a biological species is a population whose members can interbreed and produce fertile offspring.

<span>In grafting, the plant with desired root system is called the <u>rootstock</u>, and the portion of the plant with the buds is called the <u>scion</u>.
The grafting is a horticultural technique in which parts from two or more plants are joined together to grow as a one single plant.
Rootstock is the plant selected for its roots because it can provide different properties, such as fruit size, or because it is resistant to drought or diseases.
Scion is the plant selected for its leaves, flowers, fruits or stems.
