Dung beetles are beetles that feed partly or only on the dung of mammals. They are a kind of scarab beetle. All these species belong to the superfamily Scarabaeoidea, and most of them to the family Scarabaeidae. The subfamily Scarabaeinae alone has more than 5,000 species.any dung beetles, known as rollers, roll dung into balls, which are used as a food source or brooding chambers. Other dung beetles, known as tunnelers, bury the dung wherever they find it. A third group, the dwellers, neither roll nor burrow: they simply live in dung.
Collagen is the main component of connective tissue, and is the most abundant protein in mammals, making up about 25% to 35% of the whole-body protein content. An atomic-force-microscopy image of collagen fibrils in a collagen fiber.t is mostly found in fibrous tissues such as tendon, ligament and skin, and is also abundant in cornea, bone, blood vessels, cartilage, intervertebral disc and the digestive tract. In muscle tissue, collagen serves as a major component of endomysium.
Collage (from the French: coller, to glue; French pronunciation: â[kÉ.laÊ]) is a technique of an art production, primarily used in the visual arts, where the artwork is made from an assemblage of different forms, thus creating a new whole.
