mid ocean ridges occur along divergent plate boundaries
Active transport is a process requiring energy in which a substance crosses the cell membrane. When the nerve cell is in its resting potential, there are the positively charged sodium ions and the negatively charged potassium ions. During depolarization, the neuron fires, wherein the active transport plays its role: the positive ions are forced in and the negative ions are forced out. When depolarization is done, these ions are again back to normal through active transport.<span>

The classification of the characteristics and examples based on the model of speciation that is being described are as follows:
- <u>Allopatric Speciation:</u> speciation that is based on geographic isolation.
- <u>Sympatric Speciation:</u> organisms are reproductively isolated by postzygotic mechanisms and evolve into different species.
- <u>Allopatric Speciation:</u> organisms in different locations are subject to different selective pressures and evolve into different species.
- <u>Sympatric Speciation:</u> speciation that does not require geographic isolation.
- <u>Sympatric Speciation:</u> bread wheat evolved from two species of wheat with different chromosome numbers.
<h3>What is speciation?</h3>
Speciation can be defined as an ecological and biological process through which new species of a living organism are formed, especially due to isolation of a part.
<h3>The types of speciation.</h3>
In Science, there are five (5) major types of speciation and these include the following:
- Allopatric Speciation
- Peripatric Speciation
- Parapatric Speciation
- Sympatric Speciation.
- Artificial Speciation.
