Polyhedron in nature
WebA polyhedron is a 3D shape that has flat faces, straight edges, and sharp vertices (corners). The word "polyhedron" is derived from a Greek word, where 'poly' means "many" and hedron means "surface".Thus, when many flat surfaces are joined together they form a … WebBacteriophages (Greek. Phagos - eater; literally - bacteria eaters) - bacterial viruses destroy bacteria and other microorganisms. Particles consist of a hexagonal or rod-shaped head with a 45–140 nm diameter and a 10–40 thick and 100–200 nm long. The bacteriophage …
