Stratified sampling is a probability sampling method and a form of random sampling in which the population is divided into two or more groups (strata) according to one or more common attributes. Stratified random sampling intends to guarantee that the sample represents specific sub-groups or strata. Accordingly, application of stratified sampling method involves dividing population into.

Multiple cell thickness Skin, has an outer layer of dead cells (rich is keratin) that provides a tough, waterproof barrier. connective tissue. Connects and supports other tissues Includes loose connective tissue (collagen and elastin), fibrous.
Types of Stratified Sampling Proportionate Stratified Random Sampling. The sample size of each stratum in this technique is proportionate to the population size of the stratum when viewed against the entire population. This means that the each stratum has the same sampling fraction. For example, you have 3 strata with 100, 200 and 300 population sizes respectively. And the researcher chose a.
Uterine cervix (x100) go to top layer for classification (bottom near basement mb shape does not matter) thus this tissue is stratified SQUAMOUS cells (not columnar like how the bottom cells look) no evidence of keratin being produced at all thus this is the non-keratinized version boundary pt Uterine cervix (x400) Skin (x320) stratified squamous keratinized epithelium aka skin KERATIN LAYER.
The epithelial membrane is composed of epithelium attached to a layer of connective tissue, for example, your skin.The mucous membrane is also a composite of connective and epithelial tissues.Sometimes called mucosae, these epithelial membranes line the body cavities and hollow passageways that open to the external environment, and include the digestive, respiratory, excretory, and.
The epidermis is composed of keratinized, stratified squamous epithelium. It is made of four or five layers of epithelial cells, depending on its location in the body. It does not have any blood vessels within it (i.e., it is avascular). Skin that has four layers of cells is referred to as “thin skin.” From deep to superficial, these layers are the stratum basale, stratum spinosum, stratum.
