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.

Answer: Ascending colon, right colic flexure, transverse colon, left colic flexure, descending colon and sigmoid colon.
Explanation: The ascending colon is the second part of the large intestine and is located vertically; the transverse colon is the third part of the colon and is the most mobile and the longest, approximately 45 cm; the descending colon is the part of the large intestine that continues after the transverse colon down, it is the part of the large intestine in which stool accumulates and compacts; the sigmoid colon is the last portion of the large intestine and is characterized by the shape of the letter S. It measures approximately 40 centimeters and joins the descending colon with the rectum.
