Best Answer: Transitional epithelium can be stretched; thus appearing different shape if stretched or relax. Unlike stratified squamous the surface isn't flat and is covered in a glycoprotein!! Transitional epithelium is found in the Urinary system!!
A phylogenetic tree or evolutionary tree is a branching diagram or  tree  showing the inferred evolutionary relationships among various biological species or other entitiesâtheir phylogeny âbased upon similarities and differences in their physical or genetic characteristics.his is normally done by including an outgroup in the input data so that the root is necessarily between the outgroup and the rest of the taxa in the tree, or by introducing additional assumptions about the relative rates of evolution on each branch, such as an application of the molecular clock hypothesis.
In a rooted phylogenetic tree, each node with descendants represents the inferred most recent common ancestor of the descendants, and the edge lengths in some trees may be interpreted as time estimates. Each node is called a taxonomic unit. A phylogram is a phylogenetic tree that has branch spans proportional to the amount of character change. 2  A chronogram is a phylogenetic tree that explicitly represents evolutionary time through its branch spans.
