Simple epithelium is a tissue that forms the outer protective layer of the skin of the animal body, it is composed of squamous epithelium cells.
<h3>What is simple epithelium? </h3>
The simple epithelium has only one layer of cells. In this type of tissue, every cell is in direct contact with the basement membrane that is under the cell.
Generally, this type of epithelium is found in the inside areas of the body. This is probably due to its fragile nature. It forms the lining of various body cavities. These are blood and lymph vessels, heart and respiratory system, etc
Because it's a thin layer, it has some physiological advantages as well. These are faster absorption and filtration. This is useful especially when it lines the digestive tract and exchanges surfaces of the lungs.
The simple columnar epithelium is a type of epithelium that has a protective function.
Therefore, it is a tissue that forms the outer protective layer of the skin of the animal body, it is composed of squamous epithelium.

The euglena uses photosynthesis to make its own food and the paramecium uses cilia to sweep food into its oral groove
An available niche after extinction can lead to speciation because it allows the emergence of genetic variation in other competing species.
<h3>What is speciation?</h3>
Speciation is a slow process associated with the emergence of reproductive isolation barriers in a population.
These barriers lead to the absence of gene flow and eventually to the emergence of new species.
In conclusion, an available niche can lead to speciation in other competing species.
