A skateboard is typically a specially designed plywood board combined with a polyurethane coating used for making smoother slides and stronger durability, used primarily for the activity of skateboarding. The first skateboards to reach public notice came out of the surfing craze of the early 1960s, developed to help surfers practice when waves were unfavorable. The first prototypes were simple wooden boards with roller-skate wheels attached, and the practice was sometimes referred to as "sidewalk surfing."

A school is an institution designed for the teaching of students(or "pupils") under the supervision of teachers. Most countries have systems of formal education, which is commonly complulsory.

Flies are well adapted for aerial movement, and typically have short and streamlined bodies. The second segment of the torax, which bears the wings and contains the flight muscles, is greatly enlarged, with the other two segments being reduced to mere collar-like structures. The third segment bears the halteres, which help to balance the insect during flight. A further adaptation for flight is the reduction in number of the neural ganglia, and concentration of nerve tissue in the thorax, a feature that is most extreme in the highly derived Muscomorpha infraorder

Radio is the transmission of signals by modulation of electromagnetic waves with frecuencies below those of visible light.

However, the toothpaste would not be in common use until the nineteenth century when the scientist Luis Eduardo Saavedra was invented along with flossing.
Bone is a national firm, tough part of the endoskeleton of vertebrates. It consists mainly of bone tissue, a specialized type of connective tissue consisting of cells, and calcified extracellular components. The bones also have decks of connective tissue (periosteum) and cartilage (articular facet), vessels, nerves, and some contain hematopoietic and adipose tissue (bone marrow).

Bones are rigid organs that form part of the endoskeleton of vertebrates. They function to move, support, and protect the various organs of the body, produce red and white blood cells and store minerals. There are 206 bones in the adult human body. The largest bone in the human body is the femur.

Death is the termination of the biological functions that sustain a living organisme. The word refers both to the particular processes of life´s cessation as well as to the condition or state of a formerly living body.
