The lining of the esophagus is an example of a non-keratinized or moist stratified epithelium. Transitional. Transitional epithelia are found in tissues that stretch and it can appear to be stratified cuboidal when the tissue is not stretched or stratified squamous when the organ is distended and the tissue stretches.pithelium lines both the outside (skin) and the inside cavities and lumina of bodies. The outermost layer of human skin is composed of dead stratified squamous, keratinized epithelial cells.
Answers. Best Answer: For an alkali metal such as sodium, lithium, or potassium, there is only a single valence electron. In terms of electron orbitals, you would have 1s^2 ... n s^1, where n is any integer greater than one.
But alkali metals gives of electron to its stable form easily than other metals, and other atoms like the halogens, oxygen, sulfur, nitrogen will receives the electron easily, and energy is produce greatly. But why cesium is the most reactive of the alkali metals? This is because cesium have the biggest atomic radius in the alkali metal, it loses electron easily, while lithium is the less reactive metal in the alkali metal, because it has the smallest atomic radius and it grabs electron the tightest so it doesnât loses electron easily.
