You observe a tissue under a microscope. There appears to be a lumen on one side of the tissue. Lining this lumen, the cells see
m to have long, fingerlike projections. Beneath the projections, the cells seem to have the shape of shoeboxes and are packed tightly together. What type of tissue are you looking at?A. Simple Cuboidal EpitheliaB. Simple Columnar EpitheliaC. Stratified Squamous EpitheliaD. Transitional Epithelia
The correct answer is A: Simple cuboidal epithelium.
Explanation:
Simple Cuboidal Epithelium: These epithelia are formed by a single layer of cuboidal cells, that are <em>as </em>tall as they are wide. They have a rounded, central nucleus. Occasionally these cells present cilia, flagella or <em>microvillus</em> in their apical surface, lining the lumen. Microvillus are fingerlike projections. This epithelium can be found for example in the proximal convolutes renal tubule.
Viruses needs to inject the virus to an organism's body, or host cell and duplicate as many viruses, so it can be able to insert it's own clones and take over the body sooner :3
