Answer: A many-layered epithelium with cuboidal basal cells and flat cells at its surface would be classified as stratified squamous epithelium.
Explanation:
Tissues composed of multiple squamous cell layers on a basement membrane are called epithelia. Layered in <em>uninterrupted sheets, </em>the cell layers are found throughout the body in exposed areas and internal organs.
The flat basal cells found on the basement membrane divide and differentiate, to <em>form cuboidal or columnar cells</em>; these are typically underneath the squamous cells layers and are layered related to their degree of <em>differentiation.</em>
Homeostasis is the ability of an organism to stabilise its internal body metabolism in response to changes in the external environment. The ability to carry out homeostasis provides an organism a lot of freedom from the dependence on the external environment. For example, reptiles are cold blooded animals. They require the heat of the sun for body metabolism. But in the absence of heat or in case of harsh winters, the reptiles will not be able to adjust to the temperature and as a result perish. Mammals are warm-blooded animals, being able to regulate their internal body temperature as and when necessary. Winters will affect the warm-blooded animals less because their body will increase in metabolism in response to cold temperatures to raise the internal body temperature. This is possible only through homeostasis.
Biotic factors include plants, animals, microbes, etc. The important abiotic factors include the amount of sunlight in the ecosystem, the amount of oxygen and nutrients that is dissolved in the water, temperature, etc. Sunlight is one of the most important abiotic factors for marine ecosystems.
